- TransGIF
- ---------------------------------------------------------------------
-
- This program may be distributed with CAB. Separate distribution is not
- allowed.
-
-
- TRANSGIF.TTP enables one colour in a GIF image to be defined as
- transparent. All pixels of this colour are not displayed in HTML pages
- and are effectively invisible. This program provides a convienient
- method of masking any irregular edges in GIF icons and images.
-
- ATTENTION!
- This program is a primitive hack and has NO safety features whatsoever.
- Use with CAUTION, there is no guarantee the program will function
- correctly!
-
- The source file is never changed and must be in GIF87a format (e.g.
- Papillon Save).
- The destination image is always in GIF89a format (GIF87a does not
- support a transparent colour). Consequently the destination image
- cannot subsequently be used as a source image with TRANSGIF.TTP.
-
- Important!
- Verified the destination file has the correct colour set as transparent
- and displays correctly in CAB before deleting the source file, you have
- been warned!
-
- Calls:
-
- transgif.ttp <filename>
-
- Displays the entire colour palette as list of RGB values. The
- <filename> must be a GIF87a image.
-
- Example: transgif.ttp any87a.gif
-
-
- transgif.ttp <colour index> <source file> <destination file>
-
- Reads a GIF 87a image <source file>, defines the colour in <colour
- index> as transparent then saves the result as a GFI 89a image in
- <destination file>.
-
- Example: transgif.ttp 0 old87a.gif new89a.gif
