Introduction

Boost.GIL is a part of the Boost C++ Libraries.

The Boost Generic Image Library (GIL) is a C++ library that abstracts image representations from algorithms and allows writing code that can work on a variety of images with performance similar to hand-writing for a specific image type.

Documentation

• Latest release
• Branch master (latest release with minor changes)
• Branch develop

See RELEASES.md for release notes.

See CONTRIBUTING.md for instructions about how to build and run tests and examples using Boost.Build or CMake.

See example/README.md for GIL usage examples.

See example/b2/README.md for Boost.Build configuration examples.

See example/cmake/README.md for CMake configuration examples.

Requirements

NOTE: The library source code is currently being modernized for C++11.

The Boost Generic Image Library (GIL) requires:

• C++11 compiler (GCC 4.9, clang 3.3, MSVC++ 14.0 (1900) or any later version)
• Boost header-only libraries

Optionally, in order to build and run tests and examples:

• Boost.Filesystem
• Boost.Test
• Headers and libraries of libjpeg, libpng, libtiff, libraw for the I/O extension

Branches

The official repository contains the following branches:

• master This holds the most recent snapshot with code that is known to be stable.

• develop This holds the most recent snapshot. It may contain unstable code.

Community

There is number of communication channels to ask questions and discuss Boost.GIL issues:

• Mailing lists (Boost discussion policy)
  • boost-gil (recommended) official Boost.GIL mailing list (archive)
  • boost-users for all Boost users
  • boost for all Boost developers
• Slack at cpplang.slack.com with Boost channels:
  • #boost-gil (recommended) official Boost.GIL channel
  • #boost-user for all Boost users
  • #boost for all Boost users
• Gitter room boostorg/gil (old real-time chat space)
• You can also ask questions via GitHub issue.

Contributing (We Need Your Help!)

If you would like to contribute to Boost.GIL, help us improve the library and maintain high quality, there is number of ways to do it.

If you would like to test the library, contribute new feature or a bug fix, see the CONTRIBUTING.md where the whole development infrastructure and the contributing workflow is explained in details.

You may consider performing code reviews on active pull requests or help with solving reported issues, especially those labelled with:

• status/need-help
• status/need-feedback
• need-minimal-example

Any feedback from users and developers, even simple questions about how things work or why they were done a certain way, carries value and can be used to improve the library.
