Documentation ------------- More information can be found on the [Apache Commons CLI homepage](https://commons.apache.org/proper/commons-cli). The [Javadoc](https://commons.apache.org/proper/commons-cli/apidocs) can be browsed. Questions related to the usage of Apache Commons CLI should be posted to the [user mailing list](https://commons.apache.org/mail-lists.html). Getting the latest release -------------------------- You can download source and binaries from our [download page](https://commons.apache.org/proper/commons-cli/download_cli.cgi). Alternatively, you can pull it from the central Maven repositories: ```xml <dependency> <groupId>commons-cli</groupId> <artifactId>commons-cli</artifactId> <version>1.10.0</version> </dependency> ``` Building -------- Building requires a Java JDK and [Apache Maven](https://maven.apache.org/). The required Java version is found in the `pom.xml` as the `maven.compiler.source` property. From a command shell, run `mvn` without arguments to invoke the default Maven goal to run all tests and checks. Contributing ------------ We accept Pull Requests via GitHub. The [developer mailing list](https://commons.apache.org/mail-lists.html) is the main channel of communication for contributors. There are some guidelines which will make applying PRs easier for us: + No tabs! Please use spaces for indentation. + Respect the existing code style for each file. + Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change. + Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running `mvn`. + Before you pushing a PR, run `mvn` (by itself), this runs the default goal, which contains all build checks. + To see the code coverage report, regardless of coverage failures, run `mvn clean site -Dcommons.jacoco.haltOnFailure=false -Pjacoco` If you plan to contribute on a regular basis, please consider filing a [contributor license agreement](https://www.apache.org/licenses/#clas). You can learn more about contributing via GitHub in our [contribution guidelines](CONTRIBUTING.md).

See the License for the specific language governing permissions and limitations under the License. ---> [](https://github.com/apache/pdfbox/actions/workflows/codeql-analysis.yml/badge.svg) Apache PDFBox =================================================== The [Apache PDFBox](https://pdfbox.apache.org/) library is an open source Java tool for working with PDF documents. This project allows creation of new PDF documents, manipulation of existing documents and the ability to extract content from documents. PDFBox also includes several command line utilities. PDFBox is published under the Apache License, Version 2.0. PDFBox is a project of the [Apache Software Foundation](https://www.apache.org/). Binary Downloads ---------------- You can download binary versions for releases currently under development or older releases from our [Download Page](https://pdfbox.apache.org/download.cgi). Build ----- You need Java 11 (or higher) and [Maven 3](https://maven.apache.org/) to build PDFBox. The recommended build command is: mvn clean install The default build will compile the Java sources and package the binary classes into jar packages. See the Maven documentation for all the other available build options. Contribute ---------- There are various ways to help us improve PDFBox. - look at the [Issue Tracker](https://issues.apache.org/jira/browse/PDFBOX) to help us fix bugs. - answer questions on our [Users Mailing List](https://pdfbox.apache.org/mailinglists.html "Subscribe to Mailing List"). - help us enhance the [Examples](https://svn.apache.org/repos/asf/pdfbox/trunk/examples/) - help us to enhance the [PDFBox Documentation](https://gitbox.apache.org/repos/asf/pdfbox-docs) or on [GitHub](https://github.com/apache/pdfbox-docs). Support ------- **Please follow the guidelines at our [Support Page](https://pdfbox.apache.org/support.html).** If you have questions about how to use PDFBox do ask on the [Users Mailing List](/mailinglists.html "Subscribe to Mailing List"). This will get you help from the entire community. The PDFBox examples and the test code in the sources will also provide additional information. And there are additional resources available on sites such as [Stack Overflow](https://stackoverflow.com/search?q=pdfbox "Stack Overflow"). If you are sure you have found a bug the please report the issue in our [Issue Tracker](https://issues.apache.org/jira/browse/PDFBOX). Known Limitations and Problems ------------------------------ See the [Issue Tracker](https://issues.apache.org/jira/browse/PDFBOX) for the full list of known issues and requested features. Some of the more common issues are: 1. You get text like "G38G43G36G51G5" instead of what you expect when you are extracting text. This is because the characters are a meaningless internal encoding that point to glyphs that are embedded in the PDF document. The only way to access the text is to use OCR. This may be a future enhancement. 2. You get an error message like `java.io.IOException: Can't handle font width` this MIGHT be due to the fact that you don't have the **org/apache/pdfbox/resources** directory in your classpath. The easiest solution is to include the **apache-pdfbox-x.x.x.jar** in your classpath. 3. You get text that has the correct characters, but in the wrong order. This mght be because you have not enabled sorting. The text in PDF files is stored in chunks and the chunks do not need to be stored in the order that they are displayed on a page. By default, PDFBox does not sort the text.

It is a Java application that reads a formatting object tree conforming to the XSL 1.1 Recommendation (05 December 2006) and then turns it into a PDF document, certain other output formats or allows you to preview it directly on screen. Note that not all parts of the XSL 1.1 specification have yet been implemented. Apache FOP is part of Apache's XML Graphics project. The homepage of Apache FOP is http://xmlgraphics.apache.org/fop/. Legal Information ----------------- Apache FOP is published under the Apache License version 2.0. For the license text, please see the following files: - LICENSE - NOTICE Legal information on libraries used by Apache FOP can be found in the "lib/README.txt" file.

## Material Symbols / Material Icons These are two different official icon sets from Google, using the same underlying designs. Material Symbols is the current set, introduced in April 2022, built on variable font technology. Material Icons is the classic set, but no longer updated. More details below. The icons can be browsed in a more user-friendly way at https://fonts.google.com/icons. Use the popdown menu near top left to choose between the two sets; Material Symbols is the default. The icons are designed under the [material design guidelines](https://material.io/guidelines/). ## Icon Requests We’d love to support your icon needs! Please submit your request here on GitHub as an issue. Please note that Google Fonts does not accept user submissions of finished icon designs! There are fairly strict guidelines for Material icons, plus Google has upstream source files from which this repo is generated. Therefore, Google does not accept pull requests for icon files (whether new icon suggestions, or fixes for existing icons). Concepts are appreciated—just don’t design SVGs and submit them via pull request. However, users are perfectly welcome to point at outside files or images as examples—for the kind of thing they want, but they won’t just be taken “as is.” This works especially well if you have multiple examples for a single icon, to help us understand the “essence” of the idea. > For example, there is a fairly universal conceptual logo/icon for “agender,” so if you were proposing Google add an agender icon in the Material style, either mentioning that, or pointing at https://www.google.com/search?q=agender+icon would be a helpful tip. ### Third-party logos Currently, Google does not include 3rd-party logos among the Material Symbols or Material Icons due to legal reasons. Some 3rd-party logos that were included in the past have since been removed. ## npm Packages Google does not currently maintain the npm package for this repo, past v3 (2016). However, user @marella is hosting the following. He tells us these are automatically updated and published using GitHub Actions. Note: Google does **not** monitor or vet these packages. ### [material-symbols](https://github.com/marella/material-symbols/tree/main/material-symbols#readme) [](https://www.npmjs.com/package/material-symbols) [](https://packagephobia.com/result?p=material-symbols) - Only WOFF2 variable fonts and CSS for Material Symbols - Includes outlined, rounded, and sharp icons and all variations of fill, weight, grade, and optical size - Supports Sass ### [material-icons](https://github.com/marella/material-icons#readme) [](https://www.npmjs.com/package/material-icons) [](https://packagephobia.com/result?p=material-icons) [](https://www.npmjs.com/package/material-icons) - Only WOFF2, WOFF fonts and CSS - Includes outlined, round, sharp and two-tone icons - Supports Sass ### [@material-design-icons/font](https://github.com/marella/material-design-icons/tree/main/font#readme) [](https://www.npmjs.com/package/@material-design-icons/font) [](https://packagephobia.com/result?p=@material-design-icons/font) - Only WOFF2 fonts and CSS - Lighter version of `material-icons` package - Doesn't support [older browsers](https://caniuse.com/woff2) such as Internet Explorer because of dropping WOFF (v1) ### [@material-design-icons/svg](https://github.com/marella/material-design-icons/tree/main/svg#readme) [](https://www.npmjs.com/package/@material-design-icons/svg) [](https://packagephobia.com/result?p=@material-design-icons/svg) - Only SVGs - Optimizes SVGs using SVGO ## Material Symbols These newer icons can be browsed in a more user-friendly way at https://fonts.google.com/icons. Use the popdown menu near top left to choose between the two sets; Material Symbols is the default. These icons were built/designed as variable fonts first (based on the 24 px designs from Material Icons). There are three separate Material Symbols variable fonts, which also have static icons available (but those do not have all the variations available, as that would be hundreds of styles): - Outlined - Rounded - Sharp - Note that although there is no separate Filled font, the Fill axis allows access to filled styles, in all three fonts. It can also be manipulated for an animated fill effect, to indicate user selection. Each of the fonts has these design axes, which can be varied in CSS, or in many more modern design apps: - Optical Size (opsz) from 20 to 48 px. The default is 24. - Weight from 100 (Thin) to 700 (Bold). Regular is 400. - Grade from -50 to 200. The default is 0 (zero). -50 is suggested for reversed contrast (e.g. white icons on black background) - Fill from 0 to 100. The default is 0 (zero). The following directories in this repo contain specifically Material Symbols (not Material Icons) content: - symbols - variablefont What is currently _not_ available in Material Symbols? - only the 20 and 24 px versions are designed with perfect pixel-grid alignment - the only pre-made fonts are the variable fonts - there are no two-tone icons ## Material Icons The icons can be browsed in a more user-friendly way at https://fonts.google.com/icons?icon.set=Material+Icons These classic icons are available in five distinct styles: - Outlined - Filled (the font version is just called Material Icons, as this is the oldest style) - Rounded - Sharp - Two tone The following directories in this repo contain specifically Material Icons (not Material Symbols) content: - android - font - ios - png - src What is currently _not_ available in Material Icons? - variable fonts - weights other than Regular - grades other than Regular - a means to animate Fill transitions - new icons (since updates were halted in 2022) ## Material Icons update history ### 4.0.0 Update * 2020 Aug 31 * Restructured repository, updated assets. ### 3.0.1 Update * 2016 Sep 01 * Changed license in package.json. * Added missing device symbol sprites. ### 3.0.0 Update * 2016 Aug 25 * License change to Apache 2.0! ### 2.0 * 2016 May 28 ## Getting Started Read the [developer guide](https://developers.google.com/fonts/docs/material_icons) on how to use the material design icons in your project. ### Using a font The `font` and `variablefont` folders contain pre-generated font files that can be included in a project. This is especially convenient for the web; however, it is generally better to link to the web font hosted on Google Fonts: ```html <link href="https://fonts.googleapis.com/css2?family=Material+Icons" rel="stylesheet"> ``` ```html <link href="https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined" rel="stylesheet"> ``` Read more on [Material Symbols](https://developers.google.com/fonts/docs/material_symbols/) or [Material Icons](https://developers.google.com/fonts/docs/material_icons/) in the Google Fonts developer guide. ## License We have made these icons available for you to incorporate into your products under the [Apache License Version 2.0](https://www.apache.org/licenses/LICENSE-2.0.txt). Feel free to remix and re-share these icons and documentation in your products. We'd love attribution in your app's *about* screen, but it's not required.

Gumbo - A pure-C HTML5 parser. ============ [](https://travis-ci.org/google/gumbo-parser) [](https://ci.appveyor.com/project/nostrademons/gumbo-parser) Gumbo is an implementation of the [HTML5 parsing algorithm][] implemented as a pure C99 library with no outside dependencies. It's designed to serve as a building block for other tools and libraries such as linters, validators, templating languages, and refactoring and analysis tools. Goals & features: * Fully conformant with the [HTML5 spec][]. * Robust and resilient to bad input. * Simple API that can be easily wrapped by other languages. * Support for source locations and pointers back to the original text. * Support for fragment parsing. * Relatively lightweight, with no outside dependencies. * Passes all [html5lib tests][], including the template tag. * Tested on over 2.5 billion pages from Google's index. Non-goals: * Execution speed. Gumbo gains some of this by virtue of being written in C, but it is not an important consideration for the intended use-case, and was not a major design factor. * Support for encodings other than UTF-8. For the most part, client code can convert the input stream to UTF-8 text using another library before processing. * Mutability. Gumbo is intentionally designed to turn an HTML document into a parse tree, and free that parse tree all at once. It's not designed to persistently store nodes or subtrees outside of the parse tree, or to perform arbitrary DOM mutations within your program. If you need this functionality, we recommend translating the Gumbo parse tree into a mutable DOM representation more suited for the particular needs of your program before operating on it. * C89 support. Most major compilers support C99 by now; the major exception (Microsoft Visual Studio) should be able to compile this in C++ mode with relatively few changes. (Bug reports welcome.) * ~~Security. Gumbo was initially designed for a product that worked with trusted input files only. We're working to harden this and make sure that it behaves as expected even on malicious input, but for now, Gumbo should only be run on trusted input or within a sandbox.~~ Gumbo underwent a number of security fixes and passed Google's security review as of version 0.9.1. Wishlist (aka "We couldn't get these into the original release, but are hoping to add them soon"): * Full-featured error reporting. * Additional performance improvements. * DOM wrapper library/libraries (possibly within other language bindings) * Query libraries, to extract information from parse trees using CSS or XPATH. Installation ============ To build and install the library, issue the standard UNIX incantation from the root of the distribution: ```bash $ ./autogen.sh $ ./configure $ make $ sudo make install ``` Gumbo comes with full pkg-config support, so you can use the pkg-config to print the flags needed to link your program against it: ```bash $ pkg-config --cflags gumbo # print compiler flags $ pkg-config --libs gumbo # print linker flags $ pkg-config --cflags --libs gumbo # print both ``` For example: ```bash $ gcc my_program.c `pkg-config --cflags --libs gumbo` ``` See the pkg-config man page for more info. There are a number of sample programs in the examples/ directory. They're built automatically by 'make', but can also be made individually with `make <programname>` (eg. `make clean_text`). To run the unit tests, you'll need to have [googletest][] downloaded and unzipped. The googletest maintainers recommend against using `make install`; instead, symlink the root googletest directory to 'gtest' inside gumbo's root directory, and then `make check`: ```bash $ unzip gtest-1.6.0.zip $ cd gumbo-* $ ln -s ../gtest-1.6.0 gtest $ make check ``` Gumbo's `make check` has code to automatically configure & build gtest and then link in the library. Debian and Fedora users can install libgtest with: ```bash $ apt-get install libgtest-dev # Debian/Ubuntu $ yum install gtest-devel # CentOS/Fedora ``` Note for Ubuntu users: libgtest-dev package only install source files. You have to make libraries yourself using cmake: $ sudo apt-get install cmake $ cd /usr/src/gtest $ sudo cmake CMakeLists.txt $ sudo make $ sudo cp *.a /usr/lib The configure script will detect the presence of the library and use that instead. Note that you need to have super user privileges to execute these commands. On most distros, you can prefix the commands above with `sudo` to execute them as the super user. Debian installs usually don't have `sudo` installed (Ubuntu however does.) Switch users first with `su -`, then run `apt-get`. Basic Usage =========== Within your program, you need to include "gumbo.h" and then issue a call to `gumbo_parse`: ```C #include "gumbo.h" int main() { GumboOutput* output = gumbo_parse("<h1>Hello, World!</h1>"); // Do stuff with output->root gumbo_destroy_output(&kGumboDefaultOptions, output); } ``` See the API documentation and sample programs for more details. A note on API/ABI compatibility =============================== We'll make a best effort to preserve API compatibility between releases. The initial release is a 0.9 (beta) release to solicit comments from early adopters, but if no major problems are found with the API, a 1.0 release will follow shortly, and the API of that should be considered stable. If changes are necessary, we follow [semantic versioning][]. We make no such guarantees about the ABI, and it's very likely that subsequent versions may require a recompile of client code. For this reason, we recommend NOT using Gumbo data structures throughout a program, and instead limiting them to a translation layer that picks out whatever data is needed from the parse tree and then converts that to persistent data structures more appropriate for the application. The API is structured to encourage this use, with a single delete function for the whole parse tree, and is not designed with mutation in mind. Python usage ============ To install the python bindings, make sure that the C library is installed first, and then `sudo python setup.py install` from the root of the distro. This installs a 'gumbo' module; `pydoc gumbo` should tell you about it. Recommended best-practice for Python usage is to use one of the adapters to an existing API (personally, I prefer BeautifulSoup) and write your program in terms of those. The raw CTypes bindings should be considered building blocks for higher-level libraries and rarely referenced directly. External Bindings and other wrappers ==================================== The following language bindings or other tools/wrappers are maintained by various contributors in other repositories: * C++: [gumbo-query] by lazytiger * Ruby: * [ruby-gumbo] by Nicolas Martyanoff * [nokogumbo] by Sam Ruby * Node.js: [node-gumbo-parser] by Karl Westin * D: [gumbo-d] by Christopher Bertels * Lua: [lua-gumbo] by Craig Barnes * Objective-C: * [ObjectiveGumbo] by Programming Thomas * [OCGumbo] by TracyYih * C#: [GumboBindings] by Vladimir Zotov * PHP: [GumboPHP] by Paul Preece * Perl: [HTML::Gumbo] by Ruslan Zakirov * Julia: [Gumbo.jl] by James Porter * C/Libxml: [gumbo-libxml] by Jonathan Tang [gumbo-query]: https://github.com/lazytiger/gumbo-query [ruby-gumbo]: https://github.com/nevir/ruby-gumbo [nokogumbo]: https://github.com/rubys/nokogumbo [node-gumbo-parser]: https://github.com/karlwestin/node-gumbo-parser [gumbo-d]: https://github.com/bakkdoor/gumbo-d [lua-gumbo]: https://github.com/craigbarnes/lua-gumbo [OCGumbo]: https://github.com/tracy-e/OCGumbo [ObjectiveGumbo]: https://github.com/programmingthomas/ObjectiveGumbo [GumboBindings]: https://github.com/rgripper/GumboBindings [GumboPHP]: https://github.com/BipSync/gumbo [Gumbo.jl]: https://github.com/porterjamesj/Gumbo.jl [gumbo-libxml]: https://github.com/nostrademons/gumbo-libxml [HTML5 parsing algorithm]: http://www.whatwg.org/specs/web-apps/current-work/multipage/#auto-toc-12 [HTML5 spec]: http://www.whatwg.org/specs/web-apps/current-work/multipage/ [html5lib tests]: https://github.com/html5lib/html5lib-tests [googletest]: https://code.google.com/p/googletest/ [semantic versioning]: http://semver.org/ [HTML::Gumbo]: https://metacpan.org/pod/HTML::Gumbo

If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed. 4. Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that You meet the following conditions: (a) You must give any other recipients of the Work or Derivative Works a copy of this License; and (b) You must cause any modified files to carry prominent notices stating that You changed the files; and (c) You must retain, in the Source form of any Derivative Works that You distribute, all copyright, patent, trademark, and attribution notices from the Source form of the Work, excluding those notices that do not pertain to any part of the Derivative Works; and (d) If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative Works that You distribute must include a readable copy of the attribution notices contained within such NOTICE file, excluding those notices that do not pertain to any part of the Derivative Works, in at least one of the following places: within a NOTICE text file distributed as part of the Derivative Works; within the Source form or documentation, if provided along with the Derivative Works; or, within a display generated by the Derivative Works, if and wherever such third-party notices normally appear. The contents of the NOTICE file are for informational purposes only and do not modify the License. You may add Your own attribution notices within Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot be construed as modifying the License. You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License. 5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally submitted for inclusion in the Work by You to the Licensor shall be under the terms and conditions of this License, without any additional terms or conditions. Notwithstanding the above, nothing herein shall supersede or modify the terms of any separate license agreement you may have executed with Licensor regarding such Contributions. 6. Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and reproducing the content of the NOTICE file. 7. Disclaimer of Warranty. Unless required by applicable law or agreed to in writing, Licensor provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using or redistributing the Work and assume any risks associated with Your exercise of permissions under this License. 8. Limitation of Liability. In no event and under no legal theory, whether in tort (including negligence), contract, or otherwise, unless required by applicable law (such as deliberate and grossly negligent acts) or agreed to in writing, shall any Contributor be liable to You for damages, including any direct, indirect, special, incidental, or consequential damages of any character arising as a result of this License or out of the use or inability to use the Work (including but not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses), even if such Contributor has been advised of the possibility of such damages. 9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.

Independent JPEG Group License LEGAL ISSUES In plain English: 1. We don't promise that this software works. (But if you find any bugs, please let us know!) 2. You can use this software for whatever you want. You don't have to pay us. 3. You may not pretend that you wrote this software. If you use it in a program, you must acknowledge somewhere in your documentation that you've used the IJG code. In legalese: The authors make NO WARRANTY or representation, either express or implied, with respect to this software, its quality, accuracy, merchantability, or fitness for a particular purpose. This software is provided "AS IS", and you, its user, assume the entire risk as to its quality and accuracy. This software is copyright (C) 1991-1998, Thomas G. Lane. All Rights Reserved except as specified below. Permission is hereby granted to use, copy, modify, and distribute this software (or portions thereof) for any purpose, without fee, subject to these conditions: (1) If any part of the source code for this software is distributed, then this README file must be included, with this copyright and no-warranty notice unaltered; and any additions, deletions, or changes to the original files must be clearly indicated in accompanying documentation. (2) If only executable code is distributed, then the accompanying documentation must state that "this software is based in part on the work of the Independent JPEG Group". (3) Permission for use of this software is granted only if the user accepts full responsibility for any undesirable consequences; the authors accept NO LIABILITY for damages of any kind. These conditions apply to any software derived from or based on the IJG code, not just to the unmodified library. If you use our work, you ought to acknowledge us. Permission is NOT granted for the use of any IJG author's name or company name in advertising or publicity relating to this software or products derived from it. This software may be referred to only as "the Independent JPEG Group's software". We specifically permit and encourage the use of this software as the basis of commercial products, provided that all warranty or liability claims are assumed by the product vendor. ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA. ansi2knr.c is NOT covered by the above copyright and conditions, but instead by the usual distribution terms of the Free Software Foundation; principally, that you must include source code if you redistribute it. (See the file ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part of any program generated from the IJG code, this does not limit you more than the foregoing paragraphs do. The Unix configuration script "configure" was produced with GNU Autoconf. It is copyright by the Free Software Foundation but is freely distributable. The same holds for its supporting scripts (config.guess, config.sub, ltconfig, ltmain.sh). Another support script, install-sh, is copyright by M.I.T. but is also freely distributable. It appears that the arithmetic coding option of the JPEG spec is covered by patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without obtaining one or more licenses. For this reason, support for arithmetic coding has been removed from the free JPEG software. (Since arithmetic coding provides only a marginal gain over the unpatented Huffman mode, it is unlikely that very many implementations will support it.) So far as we are aware, there are no patent restrictions on the remaining code. The IJG distribution formerly included code to read and write GIF files. To avoid entanglement with the Unisys LZW patent, GIF reading support has been removed altogether, and the GIF writer has been simplified to produce "uncompressed GIFs". This technique does not use the LZW algorithm; the resulting GIF files are larger than usual, but are readable by all standard GIF decoders. We are required to state that "The Graphics Interchange Format(c) is the Copyright property of CompuServe Incorporated. GIF(sm) is a Service Mark property of CompuServe Incorporated."

"Contribution" shall mean any work of authorship, including the original version of the Work and any modifications or additions to that Work or Derivative Works thereof, that is intentionally submitted to Licensor for inclusion in the Work by the copyright owner or by an individual or Legal Entity authorized to submit on behalf of the copyright owner. For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to the Licensor or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, the Licensor for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by the copyright owner as "Not a Contribution." "Contributor" shall mean Licensor and any individual or Legal Entity on behalf of whom a Contribution has been received by Licensor and subsequently incorporated within the Work. 2. Grant of Copyright License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform, sublicense, and distribute the Work and such Derivative Works in Source or Object form. 3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with the Work to which such Contribution(s) was submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed. 4. Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that You meet the following conditions: (a) You must give any other recipients of the Work or Derivative Works a copy of this License; and (b) You must cause any modified files to carry prominent notices stating that You changed the files; and (c) You must retain, in the Source form of any Derivative Works that You distribute, all copyright, patent, trademark, and attribution notices from the Source form of the Work, excluding those notices that do not pertain to any part of the Derivative Works; and (d) If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative Works that You distribute must include a readable copy of the attribution notices contained within such NOTICE file, excluding those notices that do not pertain to any part of the Derivative Works, in at least one of the following places: within a NOTICE text file distributed as part of the Derivative Works; within the Source form or documentation, if provided along with the Derivative Works; or, within a display generated by the Derivative Works, if and wherever such third-party notices normally appear. The contents of the NOTICE file are for informational purposes only and do not modify the License. You may add Your own attribution notices within Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot be construed as modifying the License. You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License. 5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally submitted for inclusion in the Work by You to the Licensor shall be under the terms and conditions of this License, without any additional terms or conditions. Notwithstanding the above, nothing herein shall supersede or modify the terms of any separate license agreement you may have executed with Licensor regarding such Contributions. 6. Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and reproducing the content of the NOTICE file. 7. Disclaimer of Warranty. Unless required by applicable law or agreed to in writing, Licensor provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using or redistributing the Work and assume any risks associated with Your exercise of permissions under this License. 8. Limitation of Liability. In no event and under no legal theory, whether in tort (including negligence), contract, or otherwise, unless required by applicable law (such as deliberate and grossly negligent acts) or agreed to in writing, shall any Contributor be liable to You for damages, including any direct, indirect, special, incidental, or consequential damages of any character arising as a result of this License or out of the use or inability to use the Work (including but not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses), even if such Contributor has been advised of the possibility of such damages. 9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.

GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. one line to give the program's name and an idea of what it does. Copyright (C) yyyy name of author This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. signature of Ty Coon, 1 April 1989 Ty Coon, President of Vice

Welcome to the OpenSSL Project ============================== [![openssl logo]][www.openssl.org] [![github actions ci badge]][github actions ci] [](https://github.com/openssl/openssl/actions/workflows/os-zoo.yml) [](https://github.com/openssl/openssl/actions/workflows/provider-compatibility.yml) [](https://github.com/openssl/openssl/actions/workflows/run_quic_interop.yml) [](https://github.com/openssl/openssl/actions/workflows/run-checker-daily.yml) [](https://insights.linuxfoundation.org/project/openssl) OpenSSL is a robust, commercial-grade, full-featured Open Source Toolkit for the TLS (formerly SSL), DTLS and QUIC protocols. The protocol implementations are based on a full-strength general purpose cryptographic library, which can also be used stand-alone. Also included is a cryptographic module validated to conform with FIPS standards. OpenSSL is descended from the SSLeay library developed by Eric A. Young and Tim J. Hudson. The official Home Page of the OpenSSL Project is [www.openssl.org]. Table of Contents ================= - [Overview](#overview) - [Download](#download) - [Build and Install](#build-and-install) - [Documentation](#documentation) - [License](#license) - [Support](#support) - [Contributing](#contributing) - [Legalities](#legalities) Overview ======== The OpenSSL toolkit includes: - **libssl** an implementation of all TLS protocol versions up to TLSv1.3 ([RFC 8446]), DTLS protocol versions up to DTLSv1.2 ([RFC 6347]) and the QUIC version 1 protocol ([RFC 9000]). - **libcrypto** a full-strength general purpose cryptographic library. It constitutes the basis of the TLS implementation, but can also be used independently. - **openssl** the OpenSSL command line tool, a swiss army knife for cryptographic tasks, testing and analyzing. It can be used for - creation of key parameters - creation of X.509 certificates, CSRs and CRLs - calculation of message digests - encryption and decryption - SSL/TLS/DTLS and client and server tests - QUIC client tests - handling of S/MIME signed or encrypted mail - and more... Download ======== For Production Use ------------------ Source code tarballs of the official releases can be downloaded from [openssl-library.org/source/](https://openssl-library.org/source/). The OpenSSL project does not distribute the toolkit in binary form. However, for a large variety of operating systems precompiled versions of the OpenSSL toolkit are available. In particular, on Linux and other Unix operating systems, it is normally recommended to link against the precompiled shared libraries provided by the distributor or vendor. We also maintain a list of third parties that produce OpenSSL binaries for various Operating Systems (including Windows) on the [Binaries] page on our wiki. For Testing and Development --------------------------- Although testing and development could in theory also be done using the source tarballs, having a local copy of the git repository with the entire project history gives you much more insight into the code base. The main OpenSSL Git repository is private. There is a public GitHub mirror of it at [github.com/openssl/openssl], which is updated automatically from the former on every commit. A local copy of the Git repository can be obtained by cloning it from the GitHub mirror using git clone https://github.com/openssl/openssl.git If you intend to contribute to OpenSSL, either to fix bugs or contribute new features, you need to fork the GitHub mirror and clone your public fork instead. git clone https://github.com/yourname/openssl.git This is necessary because all development of OpenSSL nowadays is done via GitHub pull requests. For more details, see [Contributing](#contributing). Build and Install ================= After obtaining the Source, have a look at the [INSTALL](INSTALL.md) file for detailed instructions about building and installing OpenSSL. For some platforms, the installation instructions are amended by a platform specific document. * [Notes for UNIX-like platforms](NOTES-UNIX.md) * [Notes for Android platforms](NOTES-ANDROID.md) * [Notes for Windows platforms](NOTES-WINDOWS.md) * [Notes for the DOS platform with DJGPP](NOTES-DJGPP.md) * [Notes for the OpenVMS platform](NOTES-VMS.md) * [Notes on Perl](NOTES-PERL.md) * [Notes on Valgrind](NOTES-VALGRIND.md) Specific notes on upgrading to OpenSSL 3.x from previous versions can be found in the [ossl-guide-migration(7ossl)] manual page. Documentation ============= README Files ------------ There are some README.md files in the top level of the source distribution containing additional information on specific topics. * [Information about the OpenSSL QUIC protocol implementation](README-QUIC.md) * [Information about the OpenSSL Provider architecture](README-PROVIDERS.md) * [Information about using the OpenSSL FIPS validated module](README-FIPS.md) * [Information about the legacy OpenSSL Engine architecture](README-ENGINES.md) The OpenSSL Guide ----------------- There are some tutorial and introductory pages on some important OpenSSL topics within the [OpenSSL Guide]. Manual Pages ------------ The manual pages for the master branch and all current stable releases are available online. - [OpenSSL master](https://docs.openssl.org/master/) - [OpenSSL 3.5](https://docs.openssl.org/3.5/) - [OpenSSL 3.4](https://docs.openssl.org/3.4/) - [OpenSSL 3.3](https://docs.openssl.org/3.3/) - [OpenSSL 3.2](https://docs.openssl.org/3.2/) - [OpenSSL 3.0](https://docs.openssl.org/3.0/) Demos ----- There are numerous source code demos for using various OpenSSL capabilities in the [demos subfolder](./demos). Wiki ---- There is a [GitHub Wiki] which is currently not very active. License ======= OpenSSL is licensed under the Apache License 2.0, which means that you are free to get and use it for commercial and non-commercial purposes as long as you fulfill its conditions. See the [LICENSE.txt](LICENSE.txt) file for more details. Support ======= There are various ways to get in touch. The correct channel depends on your requirement. See the [SUPPORT](SUPPORT.md) file for more details. Contributing ============ If you are interested and willing to contribute to the OpenSSL project, please take a look at the [CONTRIBUTING](CONTRIBUTING.md) file. Legalities ========== A number of nations restrict the use or export of cryptography. If you are potentially subject to such restrictions, you should seek legal advice before attempting to develop or distribute cryptographic code.

pugixml [](https://github.com/zeux/pugixml/actions) [](https://ci.appveyor.com/project/zeux/pugixml) [](https://codecov.io/github/zeux/pugixml?branch=master)  ======= pugixml is a C++ XML processing library, which consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven tree queries. Full Unicode support is also available, with Unicode interface variants and conversions between different Unicode encodings (which happen automatically during parsing/saving). pugixml is used by a lot of projects, both open-source and proprietary, for performance and easy-to-use interface. ## Documentation Documentation for the current release of pugixml is available on-line as two separate documents: * [Quick-start guide](https://pugixml.org/docs/quickstart.html), that aims to provide enough information to start using the library; * [Complete reference manual](https://pugixml.org/docs/manual.html), that describes all features of the library in detail. You’re advised to start with the quick-start guide; however, many important library features are either not described in it at all or only mentioned briefly; if you require more information you should read the complete manual. ## Example Here's an example of how code using pugixml looks; it opens an XML file, goes over all Tool nodes and prints tools that have a Timeout attribute greater than 0: ```c++ #include "pugixml.hpp" #include <iostream> int main() { pugi::xml_document doc; pugi::xml_parse_result result = doc.load_file("xgconsole.xml"); if (!result) return -1; for (pugi::xml_node tool: doc.child("Profile").child("Tools").children("Tool")) { int timeout = tool.attribute("Timeout").as_int(); if (timeout > 0) std::cout << "Tool " << tool.attribute("Filename").value() << " has timeout " << timeout << "\n"; } } ``` And the same example using XPath: ```c++ #include "pugixml.hpp" #include <iostream> int main() { pugi::xml_document doc; pugi::xml_parse_result result = doc.load_file("xgconsole.xml"); if (!result) return -1; pugi::xpath_node_set tools_with_timeout = doc.select_nodes("/Profile/Tools/Tool[@Timeout > 0]"); for (pugi::xpath_node node: tools_with_timeout) { pugi::xml_node tool = node.node(); std::cout << "Tool " << tool.attribute("Filename").value() << " has timeout " << tool.attribute("Timeout").as_int() << "\n"; } } ``` ## License This library is available to anybody free of charge, under the terms of MIT License (see LICENSE.md).

# Tesseract OCR [](https://scan.coverity.com/projects/tesseract-ocr) [](https://github.com/tesseract-ocr/tesseract/security/code-scanning) [](https://issues.oss-fuzz.com/issues?q=is:open%20title:tesseract-ocr) \ [](https://raw.githubusercontent.com/tesseract-ocr/tesseract/main/LICENSE) [](https://github.com/tesseract-ocr/tesseract/releases/) ## Table of Contents * [Tesseract OCR](#tesseract-ocr) * [About](#about) * [Brief history](#brief-history) * [Installing Tesseract](#installing-tesseract) * [Running Tesseract](#running-tesseract) * [For developers](#for-developers) * [Support](#support) * [License](#license) * [Dependencies](#dependencies) * [Latest Version of README](#latest-version-of-readme) ## About This package contains an **OCR engine** - `libtesseract` and a **command line program** - `tesseract`. Tesseract 4 adds a new neural net (LSTM) based [OCR engine](https://en.wikipedia.org/wiki/Optical_character_recognition) which is focused on line recognition, but also still supports the legacy Tesseract OCR engine of Tesseract 3 which works by recognizing character patterns. Compatibility with Tesseract 3 is enabled by using the Legacy OCR Engine mode (--oem 0). It also needs [traineddata](https://tesseract-ocr.github.io/tessdoc/Data-Files.html) files which support the legacy engine, for example those from the [tessdata](https://github.com/tesseract-ocr/tessdata) repository. Stefan Weil is the current lead developer. Ray Smith was the lead developer until 2018. The maintainer is Zdenko Podobny. For a list of contributors see [AUTHORS](https://github.com/tesseract-ocr/tesseract/blob/main/AUTHORS) and GitHub's log of [contributors](https://github.com/tesseract-ocr/tesseract/graphs/contributors). Tesseract has **unicode (UTF-8) support**, and can **recognize [more than 100 languages](https://tesseract-ocr.github.io/tessdoc/Data-Files-in-different-versions.html)** "out of the box". Tesseract supports **[various image formats](https://tesseract-ocr.github.io/tessdoc/InputFormats)** including PNG, JPEG and TIFF. Tesseract supports **various output formats**: plain text, hOCR (HTML), PDF, invisible-text-only PDF, TSV, ALTO and PAGE. You should note that in many cases, in order to get better OCR results, you'll need to **[improve the quality](https://tesseract-ocr.github.io/tessdoc/ImproveQuality.html) of the image** you are giving Tesseract. This project **does not include a GUI application**. If you need one, please see the [3rdParty](https://tesseract-ocr.github.io/tessdoc/User-Projects-%E2%80%93-3rdParty.html) documentation. Tesseract **can be trained to recognize other languages**. See [Tesseract Training](https://tesseract-ocr.github.io/tessdoc/Training-Tesseract.html) for more information. ## Brief history Tesseract was originally developed at Hewlett-Packard Laboratories Bristol UK and at Hewlett-Packard Co, Greeley Colorado USA between 1985 and 1994, with some more changes made in 1996 to port to Windows, and some C++izing in 1998. In 2005 Tesseract was open sourced by HP. From 2006 until November 2018 it was developed by Google. Major version 5 is the current stable version and started with release [5.0.0](https://github.com/tesseract-ocr/tesseract/releases/tag/5.0.0) on November 30, 2021. Newer minor versions and bugfix versions are available from [GitHub](https://github.com/tesseract-ocr/tesseract/releases/). Latest source code is available from [main branch on GitHub](https://github.com/tesseract-ocr/tesseract/tree/main). Open issues can be found in [issue tracker](https://github.com/tesseract-ocr/tesseract/issues), and [planning documentation](https://tesseract-ocr.github.io/tessdoc/Planning.html). See **[Release Notes](https://tesseract-ocr.github.io/tessdoc/ReleaseNotes.html)** and **[Change Log](https://github.com/tesseract-ocr/tesseract/blob/main/ChangeLog)** for more details of the releases. ## Installing Tesseract You can either [Install Tesseract via pre-built binary package](https://tesseract-ocr.github.io/tessdoc/Installation.html) or [build it from source](https://tesseract-ocr.github.io/tessdoc/Compiling.html). Before building Tesseract from source, please check that your system has a compiler which is one of the [supported compilers](https://tesseract-ocr.github.io/tessdoc/supported-compilers.html). ## Running Tesseract Basic **[command line usage](https://tesseract-ocr.github.io/tessdoc/Command-Line-Usage.html)**: tesseract imagename outputbase [-l lang] [--oem ocrenginemode] [--psm pagesegmode] [configfiles...] For more information about the various command line options use `tesseract --help` or `man tesseract`. Examples can be found in the [documentation](https://tesseract-ocr.github.io/tessdoc/Command-Line-Usage.html#simplest-invocation-to-ocr-an-image). ## For developers Developers can use `libtesseract` [C](https://github.com/tesseract-ocr/tesseract/blob/main/include/tesseract/capi.h) or [C++](https://github.com/tesseract-ocr/tesseract/blob/main/include/tesseract/baseapi.h) API to build their own application. If you need bindings to `libtesseract` for other programming languages, please see the [wrapper](https://tesseract-ocr.github.io/tessdoc/AddOns.html#tesseract-wrappers) section in the AddOns documentation.

# text-encoding-detect This is a C++ and C# library for detecting UTF8 and UTF16 text encoding. I recently had to upgrade the text file handling feature of [AutoIt](https://www.autoitscript.com/site/autoit/) to better handle text files where no [byte order mark](http://en.wikipedia.org/wiki/Byte_order_mark) (BOM) was present. The older version of code I was using worked fine for UTF-8 files (with or without BOM) but it wasn't able to detect UTF-16 files without a BOM. I tried to use the [IsTextUnicode](http://msdn.microsoft.com/en-us/library/windows/desktop/dd318672(v=vs.85).aspx) Win32 API function but this seemed extremely unreliable and wouldn't detect UTF-16 Big-Endian text in my tests. With UTF-16 detection, there is always an element of ambiguity. [This post](http://blogs.msdn.com/b/oldnewthing/archive/2007/04/17/2158334.aspx) by Raymond shows that however you try and detect encoding there will always be some sequence of bytes that will make your guesses look stupid. That said, here are the detection methods I'm currently using for the various types of text file. The order of the checks I perform are: * BOM * UTF-8 * UTF-16 (newline) * UTF-16 (null distribution) ## BOM Detection I assume that if I find a BOM at the start of the file that it is valid. Although it's possible that the BOM could just be ANSI text, it's highly unlikely. The BOMs are as follows: |Encoding |BOM | |----------------------|------------------| | UTF-8 | 0xEF, 0xBB, 0xBF | | UTF-16 Little Endian | 0xFF, 0xFE | | UTF-16 Big Endian | 0xFE, 0xFF | ## UTF-8 Detection UTF-8 checking is reliable with a very low chance of false positives, so this is done first. If the text is valid UTF-8 but all the characters are in the range **0-127** then this is essentially ASCII text and can be treated as such - in this case I don't continue to check for UTF-16. If a character is in the range of **0-127** then it is a single character and nothing more needs to be done. Values **above 127** indicate multibyte encoding using the next 1, 2 or 3 bytes. |First Byte |Number of Bytes in Sequence| |-----------|---------| | 0-127 | 1 byte | | 194-223 | 2 bytes | | 224-239 | 3 bytes | | 240-244 | 4 bytes | These additional bytes are in the range **128-191**. This scheme means that if we decode the text stream based on this method and no unexpected sequences occur then this is almost certainly UTF-8 text.   ## UTF-16 Detection UTF-16 text is generally made up of 2-byte sequences (technically, there can be a 4-byte sequence with surrogate pairs). Depending on the endianness of the file the unicode character 0x1234 could be represented in the character stream as "0x12 0x34" or "0x34 0x12".  The BOM is usually used to easily determine if the file is in big or little endian mode. Without a BOM this is a little more tricky to determine. I use two methods to try and determine if the text is UTF-16 and the endianness. The first is the newline characters 0x0a and 0x0d. Depending on the endianness they will be sequenced as "0x0a 0x00" or "0x00 0x0a". If every instance of these characters in a text file is encoded the same way then that is a good sign that the text is UTF-16 and if it is big or little endian. The drawback of this method is that it won't work for very small amounts of text, or files that don't contain newlines. The second method relies on the fact that many files may contain large amounts of pure ASCII text in the range 0-127. This applies especially to files generally used in IT like scripts and logs. When encoded in UTF-16 these are represented as the ASCII character and a null character. For example, space, 0x20 would be encoded as "0x00 0x20" or "0x20 0x00". Depending on the endianness this will result in a large amount of nulls in the odd or even byte positions. We just need to scan the file for these odd and even nulls and if there is a significant percentage in the expected position then we can assume the text is UTF-16.   ## The Library There are separate libraries for C++ and C#. The notes/enums here are for the C# version. The two main public functions are: public Encoding CheckBom(byte[] buffer, int size) public Encoding DetectEncoding(byte[] buffer, int size) These functions return the Encoding which is the following enum: public enum Encoding { None, // Unknown or binary Ansi, // 0-255 Ascii, // 0-127 Utf8Bom , // UTF8 with BOM Utf8NoBom, // UTF8 without BOM Utf16LeBom, // UTF16 LE with BOM Utf16LeNoBom, // UTF16 LE without BOM Uft16BeBom, // UTF16-BE with BOM Utf16BeNoBom // UTF16-BE without BOM } The DetectEncoding function takes a byte buffer and a size parameter. The larger the buffer that is used, the more accurate the result will be. I'd recommend at least 4KB. Here is an example of passing a buffer to the DetectEncoding function: // Detect encoding var textDetect = new TextEncodingDetect(); TextEncodingDetect.Encoding encoding = textDetect.DetectEncoding(buffer, buffer.Length); Console.Write("Encoding: "); if (encoding == TextEncodingDetect.Encoding.None) { Console.WriteLine("Binary"); } else if (encoding == TextEncodingDetect.Encoding.Ascii) { Console.WriteLine("ASCII (chars in the 0-127 range)"); } else if (encoding == TextEncodingDetect.Encoding.Ansi) { Console.WriteLine("ANSI (chars in the range 0-255 range)"); } else if (encoding == TextEncodingDetect.Encoding.Utf8Bom || encoding == TextEncodingDetect.Encoding.Utf8NoBom) { Console.WriteLine("UTF-8"); } else if (encoding == TextEncodingDetect.Encoding.Utf16LeBom || encoding == TextEncodingDetect.Encoding.Utf16LeNoBom) { Console.WriteLine("UTF-16 Little Endian"); } else if (encoding == TextEncodingDetect.Encoding.Utf16BeBom || encoding == TextEncodingDetect.Encoding.Utf16BeNoBom) { Console.WriteLine("UTF-16 Big Endian"); } ## Nulls and Binary One quirk of the library is how I chose to handle nulls (0x00). These are technically valid in UTF-8 sequences, but I've assumed that any file that contains a null is not ANSI/ASCII/UTF-8. Allowing nulls for UTF-8 can cause a false return where UTF-16 text containing just ASCII can appear to be valid UTF-8. To disable this behaviour just set the **NullSuggestsBinary** property on the library to **false** before calling **DetectEncoding**. In practice, most text files don't contain nulls and the defaults are valid.

# utf8proc [](https://github.com/JuliaStrings/utf8proc/actions/workflows/build-ci.yml) [](https://ci.appveyor.com/project/StevenGJohnson/utf8proc) [utf8proc](http://juliastrings.github.io/utf8proc/) is a small, clean C library that provides Unicode normalization, case-folding, and other operations for data in the [UTF-8 encoding](http://en.wikipedia.org/wiki/UTF-8). It was [initially developed](http://www.public-software-group.org/utf8proc) by Jan Behrens and the rest of the [Public Software Group](http://www.public-software-group.org/), who deserve *nearly all of the credit* for this package. With the blessing of the Public Software Group, the [Julia developers](http://julialang.org/) have taken over development of utf8proc, since the original developers have moved to other projects. utf8proc is used for basic Unicode support in the [Julia language](http://julialang.org/), and the Julia developers became involved because they wanted to add Unicode 7 support and other features; it is now regularly updated to keep up with recent Unicode releases. There are also utf8proc wrappers for [Ruby](https://www.ruby-toolbox.com/projects/utf8_proc) and [Rust](https://docs.rs/utf8proc/latest/utf8proc/) ([github](https://github.com/Techcable/utf8proc.rs)). (The original utf8proc package also included PostgreSQL bindings.) The utf8proc package is licensed under the free/open-source [MIT "expat" license](http://opensource.org/licenses/MIT) (plus certain Unicode data governed by the similarly permissive [Unicode data license](http://www.unicode.org/copyright.html#Exhibit1)); please see the included `LICENSE.md` file for more detailed information. ## Quick Start Typical users should download a [utf8proc release](http://juliastrings.github.io/utf8proc/releases/) rather than cloning directly from github. For compilation of the C library, run `make`. You can also install the library and header file with `make install` (by default into `/usr/local/lib` and `/usr/local/bin`, but this can be changed by `make prefix=/some/dir`). `make check` runs some tests, and `make clean` deletes all of the generated files. Alternatively, you can compile with `cmake`, e.g. by ```sh mkdir build cmake -S . -B build cmake --build build ``` ### Using other compilers The included `Makefile` supports GNU/Linux flavors and MacOS with `gcc`-like compilers; Windows users will typically use `cmake`. For other Unix-like systems and other compilers, you may need to pass modified settings to `make` in order to use the correct compilation flags for building shared libraries on your system. For HP-UX with HP's `aCC` compiler and GNU Make (installed as `gmake`), you can compile with ``` gmake CC=/opt/aCC/bin/aCC CFLAGS="+O2" PICFLAG="+z" C99FLAG="-Ae" WCFLAGS="+w" LDFLAG_SHARED="-b" SOFLAG="-Wl,+h" ``` To run `gmake install` you will need GNU coreutils for the `install` command, and you may want to pass `prefix=/opt libdir=/opt/lib/hpux32` or similar to change the installation location. ### Using with CMake A CMake Config-file package is provided. To use utf8proc in a CMake project: ```cmake add_executable (app app.c) find_package (utf8proc 2.9.0 REQUIRED) target_link_libraries (app PRIVATE utf8proc::utf8proc) ``` ## General Information The C library is found in this directory after successful compilation and is named `libutf8proc.a` (for the static library) and `libutf8proc.so` (for the dynamic library). The Unicode version supported is 17.0.0. For Unicode normalizations, the following options are used: * Normalization Form C: `STABLE`, `COMPOSE` * Normalization Form D: `STABLE`, `DECOMPOSE` * Normalization Form KC: `STABLE`, `COMPOSE`, `COMPAT` * Normalization Form KD: `STABLE`, `DECOMPOSE`, `COMPAT` ## C Library The documentation for the C library is found in the `utf8proc.h` header file. `utf8proc_map` is function you will most likely be using for mapping UTF-8 strings, unless you want to allocate memory yourself. ## To Do See the Github [issues list](https://github.com/JuliaLang/utf8proc/issues). ## Contact Bug reports, feature requests, and other queries can be filed at the [utf8proc issues page on Github](https://github.com/JuliaLang/utf8proc/issues). ## See also An independent Lua translation of this library, [lua-mojibake](https://github.com/differentprogramming/lua-mojibake), is also available. ## Examples ### Convert codepoint to string ```c // Convert codepoint `a` to utf8 string `str` utf8proc_int32_t a = 223; utf8proc_uint8_t str[16] = { 0 }; utf8proc_encode_char(a, str); printf("%s\n", str); // ß ``` ### Convert string to codepoint ```c // Convert string `str` to pointer to codepoint `a` utf8proc_uint8_t str[] = "ß"; utf8proc_int32_t a; utf8proc_iterate(str, -1, &a); printf("%d\n", a); // 223 ``` ### Casefold ```c // Convert "ß" (U+00DF) to its casefold variant "ss" utf8proc_uint8_t str[] = "ß"; utf8proc_uint8_t *fold_str; utf8proc_map(str, 0, &fold_str, UTF8PROC_NULLTERM | UTF8PROC_CASEFOLD); printf("%s\n", fold_str); // ss free(fold_str); ``` ### Normalization Form C/D (NFC/NFD) ```c // Decompose "\u00e4\u00f6\u00fc" = "äöü" into "a\u0308o\u0308u\u0308" (= "äöü" via combining char U+0308) utf8proc_uint8_t input[] = {0xc3, 0xa4, 0xc3, 0xb6, 0xc3, 0xbc}; // "\u00e4\u00f6\u00fc" = "äöü" in UTF-8 utf8proc_uint8_t *nfd= utf8proc_NFD(input); // = {0x61, 0xcc, 0x88, 0x6f, 0xcc, 0x88, 0x75, 0xcc, 0x88} // Compose "a\u0308o\u0308u\u0308" into "\u00e4\u00f6\u00fc" (= "äöü" via precomposed characters) utf8proc_uint8_t *nfc= utf8proc_NFC(nfd); free(nfd); free(nfc); ```
