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.
