Gutenprint (formerly Gimp-Print) is a collection of printer drivers for Unix/Linux that currently supports over 1400 printers. It emphasizes quality and flexibility, offering a wide variety of options to meet most printing needs. It includes a CUPS driver, an IJS-based Ghostscript driver, Foomatic data, an enhanced Print plugin for The GIMP, and other printer maintenance utilities. It can be used equally well for fast printing of text or critical printing of high quality graphics and photographs.
GIMP SCRIPT-FUs is a collection of SCRIPT-FUs that have been modified to work with the most recent versions of GIMP. The compiler of this collection is usually not the original author for most of the scripts, but was able to tweak or get them working better in the latest GIMP releases and consolidate them in a sane menu hierarchy.
GQview is an image viewer for X windows. Features include single click file viewing, external editor support, thumbnail previews, thumbnail caching, and adjustable zoom. GQView has the ability to compare files and list similar or duplicate images based on content. Full screen view and slideshows allow for basic presentation of images. The program offers simple image file management with the ability to copy, move, rename, and delete files. Image collections, similar to a song playlist, are also supported.
LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others). LibRaw is based on the source codes of the dcraw utility, though some of the drawbacks of dcraw have been eliminated. The users of the library are provided with an API to be used when writing their software programs.
ExactImage is a fast C++ image processing library. Unlike ImageMagick, it allows operation in several color spaces and bit depths natively, resulting in much lower memory and computational requirements. Some optimized algorithms operate in 1/20 of the time ImageMagick requires, and displaying large images can be as fast as 1/10 of the time the "display" program takes.
xCHM is a cross-platform GUI frontend for CHMLIB, written with wxGTK. It is able to display the topics tree, work with displayed pages history, print the current page, work with bookmarks, change fonts and fast search through all the pages of the loaded .chm document. Being indirectly dependent on GTK+, the possibility of changing GTK+ skins makes xCHM theme-friendly.
DirectFB is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, an integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer device. It is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware.
