NAME
giftext - A program to dump (text only) general information about GIF
file.
USAGE
giftext [-q] [-c] [-e] [-z] [-p] [-r] [-h] gif-file
If no gif-file is given, GifText will try to read a GIF file from
stdin.
As giftext can generate huge amounts 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.
MEMORY REQUIRED
Line.
OPTIONS
[-q]
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls
printout of running scan lines. Use -q- to invert.
[-c]
Dumps the color maps.
[-e]
Dumps 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.
[-z]
Dumps the LZ codes of the image. Dumps in hex - 3 digits per
code (as we are limited to 12 bits).
[-p]
Dumps the pixels of the image. Dumps in hex - 2 digit per
pixel (<=byte).
[-r]
Dumps raw pixels as one byte per pixel. This option inhibits
all other options and only the pixels are dumped. This option
may be used to convert GIF files into raw data. Note: the color
map can be extracted by gifclrmp utility. If more than one
image is included in the file, all images will be dumped in
order.
[-h]
Print one line of command line help, similar to Usage above.
