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.
