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.
