- GifText
- -------
-
- Program to print (text only) general information about GIF file
-
- Usage:
- ------
-
- Usage: GifText [-q] [-c] [-e] [-z] [-p] [-r] [-h] GifFile
-
- If no GifFile is given, GifText will try to read stdin for GIF file.
- As giftext can generate huge amount of data, ^C will kill it, but 'q' will
- stop only the printing (of one of -e, -z, -p), while file integrity will still
- be checked.

- Options:
- --------
-
- 1. [-q] : quite mode. Default off on MSDOS, on on unix. Controls printout
- of running scan lines. Use -q- to turn off.
- 2. [-c] : Dumps also color maps.
- 3. [-e] : Dumps also encoded bytes - the pixels after compressed using LZ
- algorithm and chained to form bytes. This is the form the data is saved
- in the GIF file. Dumps in hex - 2 digit per byte.
- 4. [-z] : Dumps also the LZ codes of the image. Dumps in hex - 3 digits per
- code (as we are limited to 12 bits).
- 5. [-p] : Dumps aslo the pixels of the image. Dumps in hex - 2 digit per
- pixel (<=byte).
- 6. [-r] : Dumps raw pixels as one byte per pixel. This option inhibit all other
- options and only the pixels are dumped. This option may be used to convert
- gif file into raw data. Note the color map can be extracted by gifclrmp
- utility. If more than one image exists, all images will be dumped in order.
- 7. [-h] : print one command line help, similar to Usage above.
