giftext(1)
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.
