GIFTEXT(1) GIFLIB Documentation GIFTEXT(1)NAMEgiftext - dump GIF pixels and metadata as text
SYNOPSISgiftext [-v] [-c] [-e] [-z] [-p] [-r] [-h] [gif-file]
DESCRIPTION
A program to dump (text only) general information about GIF file.
If no GIF file is given, giftext will try to read a GIF file from
stdin.
OPTIONS-v
Verbose mode (show progress). Enables printout of running scan
lines.
-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.
