GIFBLAST is a compressor designed especially for GIF files. The usual file compressors (PKZIP, ARJ, etc.) do not work on GIF files; GIFBLAST does. When you run GIFBLAST on a GIF file X.GIF, you get a compressed file X.GFB that is usually 20-25% smaller. In order to view this file you have to decompress X.GFB to get back the original X.GIF file. The compression used in GIFBLAST is lossless, i.e. it perfectly preserves all image pixels and other information in GIF files. What can I use GIFBLAST for? The compression/decompression algorithm used in GIFBLAST is quite slow, so you would probably not want to store frequently viewed GIF files in compressed form. However, GIFBLAST should be useful in applications where getting maximum compression is important, such as: - Storing GIF files on bulletin boards for downloading. - Posting GIF files on usenet. - Transmitting GIF files via modem. - Sending GIF files on floppy disk. Because there is no loss involved when compressing with GIFBLAST, the user need not be concerned with harming the image or introducing compression artifacts.
