INTERGIF 6.15 is a program for joining GIFs together (for animation), or splitting animations apart, or for optimising animations created by other programs. * Supports the animation, transparency and interleaving features of GIF89a. * Eliminates unused palette entries. * Minimises the final size of the GIF with a devious and cunning optimisation routine: almost every animated GIF the author has found on the web ends up smaller when run through InterGif. * Can forcibly reduce a GIF's palette to the standard Acorn 256-colour palette, or to a 216-entry "web safe" colour cube (as used on the Macintosh and by most Windows browsers),or to a palette file you supply. Alternatively, it can calculate the best palette for displaying the GIF, and then reduce to that. * From version 6.03, this also works with 16bpp and 24bpp input images -- and with GIFs which use more than 256 colours in total. (GIFs can only use 256 colours per frame, but each frame can have its own palette.) * Lets you trim away any wholly transparent rows or columns from the edges of your GIF (whether single-frame or animated). * Can dither 16bpp or 24bpp input files to whatever palette is required (error diffusion implementation kindly donated by Martin Wurthner).

The Jave project is a Java based ASCII-Art-graphic editor. It allows drawing new images as well as converting JPG-Images to ASCII-Art.

JBIG-KIT implements a highly effective data compression algorithm for bi-level high-resolution images such as fax pages or scanned documents. This is a portable library of compression and decompression functions with a documented interface that can be included into your image or document processing software. Also provided are ready-to-use compression and decompression programs with a simple command line interface (similar to the converters found in Jef Poskanzer's PBM conversion package). JBIG-KIT implements the specification International Standard ISO/IEC 11544:1993 and ITU-T Recommendation T.82(1993), "Information technology - Coded representation of picture and audio information - progressive bi-level image compression", <http://www.itu.ch/itudoc/itu-t/rec/t/t82_23822.html>, which is commonly referred to as the "JBIG standard". JBIG (Joint Bi-level Image experts Group) is the committee which developed this international standard for the lossless compression of images using arithmetic coding. Like the well-known compression algorithms JPEG and MPEG, also JBIG has been developed and published by the International Organization for Standardization (ISO) and the International Telecommunication Union (ITU) (see also <http://www.iso.ch/> and <http://www.itu.ch/>).

This is a port of jgraph, a powerful program for generating graphs in postscript format. The Winter 1993 Usenix Technical Conference proceedings contains a paper describing jgraph. Also, see the jgraph homepage for more details.
