GSEGrafix GSEGrafix is a GNOME application which uses an anti-aliased GNOME canvas for creating scientific and engineering plots. The program is written in C and reads ASCII plot-parameter files and data files. The plot-parameter files contain keywords and corresponding arguments for specifying plot parameters (such as data file names, data file formats, plot type, plot style, axis type, axis labels, etc). GSEGrafix can make rectangular two-dimensional plots (with linear, semilog, or loglog axes), histograms, polar-axis plots, and three-dimensional plots (with linear axes). Three-dimensional plots include points, contour, color, and mesh plots. Data for three-dimensional plots can also be used to create two-dimensional plots using contour lines or color to represent values of a third variable.

KolourPaint 'KolourPaint' is an easy-to-use paint program for KDE. Features include undo/redo, more than a dozen tools, selections, transparent image editing and zoom support (with an optional grid and thumbnail).

OGLFT The OpenGL/FreeType2 Text Rendering Library (OGLFT) supplies an interface between a font and an OpenGL or Mesa application.It uses the FreeType library to read font faces from their files and renders text strings as OpenGL primitives. Characters can be rendered in a variety of ways, including as raster images, as tessellated polygons and as texture maps. Glyphs can be drawn individually or as a string, and can be rendered using UNICODE characters via the QString class (with Qt support). You can also combine several fonts together in one OGLFT Face to increase the coverage of UNICODE points or for other special effects. Strings can be rotated through any angle, and drawn right, centered or left justified. Additionally each character in a string can be rotated through a given angle.

SANE `Scanner Access Now Easy' is a universal interface that lets you get images from any device that produces raster images, including flatbed scanners, video and still cameras, and frame grabbers. With SANE you can write image-processing applications without worrying about peculiarities of individual devices. SANE also makes it possible to write a device driver once and only once, which t then can be used by any SANE-compliant application. SANE includes several scanner front-ends: scanimage, a command-line interface; xscanimage, a graphical front-end; and xcam, for acquiring images continuously from cameras.

Sam2p sam2p is a UNIX command line utility written in ANSI C++ that converts many raster (bitmap) image formats into Adobe PostScript or PDF files and several other formats. The images are not vectorized. sam2p gives full control to the user to specify standards-compliance, compression, and bit depths. In some cases sam2p can compress an image 100 times smaller than the PostScript output of many other common image converters. sam2p provides ZIP, RLE and LZW (de)compression filters even on Level1 devices.

Tile Driller Tile Driller is a simple paint program for drawing tile-based graphics pixel by pixel. Editing takes place in 32bit RGBA color space, so you can easily paint the alpha channel. It reads BMP, JPEG, PCX, and PNG images, but writes only PNG images.

Waterworks The goal of 'waterworks' is to provide a high-level realtime compositing system. Unlike realtime rendering systems (open-gl, directx), so far there has been little development toward a free equivalent in the realm of compositing (where 2d raster images are manipulated to create various effects.) In it's current implementation 'waterworks' is a rough prototype of a working system - and must be redesigned before serious development can occur. in the meantime, the current version is fun to play with - and gives insight into future applications (user interfaces, games, webcams, etc.)
