The GraphViz class allows for the creation of and the work with directed and undirected graphs and their visualization with AT&T's GraphViz tools.

The PEAR::Image_Transform provides a standard interface to manipulate images using different libraries

GD module is an interface to the GD library written by Thomas Bouttel. It has been extended in some ways from the original GD library.

Recoverjpeg tries to recover JFIF (JPEG) pictures from a peripheral. This may be useful if you mistakenly overwrite a partition or if a device such as a digital camera memory card is bogus.

rgbPaint is a very basic GTK+2.6 (or later) based program designed for editing pixel based images. It is a fork of mtPaint 3.09. It can only edit and save RGB images to PNG, JPEG, or ICO files. It can read PNG, JPEG, TIFF, GIF, ICO, files and possibly others like TGA, PCX, and SVGi if they are installed with your version of GTK+2.

The SDL_gfx library evolved out of the SDL_gfxPrimitives code which provided basic drawing routines such as lines, circles or polygons and SDL_rotozoom which implemented a interpolating rotozoomer for SDL surfaces. The current components of the SDL_gfx library are: - Graphic Primitives (SDL_gfxPrimitves.h) - Rotozoomer (SDL_rotozoom.h) - Framerate control (SDL_framerate.h) - MMX image filters (SDL_imageFilter.h)

Library to convert TIFF files into multi-page TIFF files. It contains only one function callable by programs: int TiffAppend(const char *outfile, const char *infile); It will insert images from infile as additional pages to outfile. Infile and outfile must be names of two existing TIFF files. The function returns 0 on success, non-0 otherwise. The code for this library was written by Peter van Vloten <pixelpan@aol.com> and was published in May 1999 issue of Windows Developer's Journal (sic!).

Synaesthesia is a program that represents music graphically in real time as coruscating field of fog and glowing lines. It is intended as a visual accompaniment to music. Synaesthesia seeks to provide not just a visual representation of sound, but a representation of how sound is perceived. Its display combines information about frequency, location, and diffuseness of sound. The display is sufficiently detailed to allow to distinguish several individual instruments, singers, or special effects on screen by their location, shape and color, and sufficiently fast to distinguish individual drum beats and notes.

Provides a wrapper to the ImageMagick/GraphicsMagick library.
