NAME

       giftext - dump GIF pixels and metadata as text

SYNOPSIS

       giftext [-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.
