VIGRA stands for Vision with Generic Algorithms. It is an image processing and analysis library that puts its main emphasis on customizable algorithms and data structures. It is particularly strong for multi-dimensional image processing.

libjpeg-turbo is a JPEG image codec that accelerates baseline JPEG compression and decompression using SIMD instructions: MMX on x86, SSE2 on x86-64, NEON on ARM, and AltiVec on PowerPC processors. Even on other systems, its highly-optimized Huffman coding routines allow it to outperform libjpeg by a significant amount. libjpeg-turbo implements both the traditional libjpeg API and the less powerful but more straightforward TurboJPEG API, and provides a full-featured Java interface. It supports color space extensions that allow it to compress from and decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.).

Phockup is a media sorting tool that uses creation date and time information in photos and videos to organize them into folders by year, month and day. All files which are not images or videos or those which do not have creation date information will be placed in a folder called unknown.

Libmng is the MNG (Multiple-image Network Graphics) reference library.

Libiptcdata is a C library for manipulating the International Press Telecommunications Council (IPTC) metadata stored within multimedia files such as images. This metadata can include captions and keywords, often used by popular photo management applications. The library provides routines for parsing, viewing, modifying, and saving this metadata.

LodePNG is a PNG image decoder and encoder, all in one, no dependency or linkage required. It's made for C (ISO C90), and has a C++ wrapper with a more convenient interface on top.

The libUEMF library is a portable C99 implementation for reading and writing WFM, EMF, and EMF+ files.

Libicns is a library for the manipulation of Mac OS IconFamily resource type files (ICNS). icns2png and png2icns are provided to convert between PNG and ICNS. icns2png will extract image files from ICNS files under names like "Foo_48x48x32.png" useful for installing for use with .desktop files. Additionally, icontainer2png is provided for extracting icontainer icon files.

Mtpaint is a graphic editing program which uses the GTK+ toolkit. It can create and edit indexed palette or 24bit RGB images, offers basic painting and palette manipulation tools. It also handles JPEG, JPEG2000, GIF, TIFF, WEBP, BMP, PNG, XPM formats.

This is a tiny, header-only C++ library for manipulating INI files.

Collection of graphics images created to test PNG applications like viewers, converters and editors. As far as that is possible, all formats supported by the PNG standard are represented.

Steghide is a program to `hide' data in various kinds of image and audio files. This practice is known as steganography, but the method used by steghide is not very secure and should not be used where security is at stake. Even if a password is used, steghide offers little plausible deniability.

Nonetheless, neither color nor sample frequencies are changed, making the embedding resistant against first-order statistical tests not aimed specifically at this tool.

MyPaint is a simple drawing and painting program that works well with Wacom-style graphics tablets.

GraphicsMagick provides a comprehensive collection of utilities, programming interfaces, and GUIs, to support file format conversion, image processing, and 2D vector rendering.

ImageMagick is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

This Perl extension allows the reading, manipulation and writing of a large number of image file formats using the ImageMagick library. Use it to create, edit, compose, or convert bitmap images from within a Perl script.

Inferno is a virtualised operating system that can run natively across a wide range of processor architectures or hosted on a wide range of operating systems. The principal components of the system are:

• The Inferno kernel which can run both native and hosted on a range of platforms and which presents the same interface to programs in both cases.

• The Dis virtual machine.

• Styx - the tiny broad-spectrum file service protocol.

• Limbo - a new simple, modular, concurrent programming language.

• Tk and Prefab - graphical user interface (GUI) primitives without a lot of goo.

• The portable cross-development suites that allow any native Inferno platform to be cross-compiled on any hosted system.

This package provides hosted Inferno.

GNU InklingReader is a package to support the Wacom Inkling device, including data conversion to various free formats, basic editing features, and an Inkscape plugin.

Inkscape is a vector graphics editor. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an XML-based W3C standard, as the native format.
