graphics/intergif 6.15 FreeBSD

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).
