-
- ABOUT
-
- TAPGIF is a program that converts an ILBM picture to GIF format
- without changing the picture's palette information. This is for
- direct conversions, and does not handle HAM, EHB, or the other
- variations from the norm correctly.
-
- I use it specifically for converting 640x480/8 AGA pics with
- Windows identity palettes to GIF format without disturbing the
- palette. There is a program called AM2GIF that will do HAM and so
- on, but does not support AGA. And unfortunately ImageMaster and
- PPM, which can both write GIFs, also both insist on fooling with
- the palette in the process.
-
- If the IFF picture contains an ANNO chunk, then the GIF file will
- be written with a GIF89a signature and a comment extension block
- will be added containing the annotation. This can be prevented by
- specifying an empty NOTE string on the command line.
-
- TAPGIF is written by John Bickers using SAS C 6.51.
-
-
- REQUIREMENTS
-
- TAPGIF requires a machine with KS 2.0, and also requires the IFF
- library. This library can be found on the Aminet sites.
-
-
- PARAMETERS
-
- The command template is...
-
- FROM/A,TO/A,NOTE/K
-
- where...
-
- FROM Is the name of an IFF ILBM picture to convert.
-
- TO Is the name of the GIF picture you want created.
-
- NOTE An optional comment to be added to the GIF file. This
- will cancel any ANNO chunk that may be in the IFF
- file, and the file will be written with a GIF89a
- signature.
-
-
- CREDITS
-
- TAPGIF is written by John Bickers using SAS C 6.51.
-
- GIF compression is performed by a modified version of the LZW code
- in Jef Poskanzer's PPMTOGIF program, which in turn is based on the
- LZW code in the Unix compress program.
-
- Christian A. Weber's iff.library is used for loading ILBM files.
