- AMGIF vn 2.0 - Amiga IFF to GIF converter
-
- - The only real change between earlier versions of Amgif, and this one
- is the addition of support for Extra-Halfbrite mode.
-
-
- Converts Amiga IFF pictures to GIF. Supports 320x200 & 320x400 in up to
- 32 colors or HAM mode, and 640x200 & 640x400 in up to 16 colors. HAM mode
- pictures are reduced to 256 colors. Also supports Extra-Halfbrite modes.
-
- This program is basically the same as IFF2GIF, by Steve Wilhite (and uses
- the modules COMPRESS.C and BUILDGIF.C from that program...), but will also
- convert HAM pictures and Extra-Halfbrite pictures. It also might be a bit
- faster with non-HAM pictures. It is used identically to IFF2GIF.
-
- It does, however, require a significant amount of memory to run. (roughly
- 200-300K, depending on resolution...) It can also require over 512K for
- pictures in Hires interlaced mode (ie 640 x 400). If you only have 512K
- and run out of memory on higher resolution images, you can still
- use IFF2GIF for those images.
-
- HAM images can take a significant amount of time to encode, mainly due to
- the calculations required to sort and remap the colors. HAM images are
- reduced to a 256 color map, choosing the most frequently used colors for
- the color map, and remapping all the other used colors to the nearest
- match in that color map. Many HAM images will not suffer much from this.
- Others may suffer significantly. It depends on the image.
-
- Thanks to Steve Wilhite, who wrote COMPRESS.C and BUILDGIF.C, which
- are used in this program. He also wrote IFF2GIF.C, which I heavily
- remodeled to become AMGIF.
-
- Thanks also to Jim Kent, who wrote JIFF.C, which is also used, in
- somewhat modified form, in this program to read IFF pics.
