GRR Free DOS utility: GIF file info displayer Version 1.00 - August 19, 1993 (c) 1993 by David Daniel Anderson Reign Ware GRR displays information about GIF files in the current or specified directory. Usage: GRR directory and/or file_spec[.GIF] Example: GRR cindyc* Example: GRR b:\fash-*.gif Usage is pretty straightforward, just run GRR followed by the files you want info about. GRR can use DOS wildcards (? and *), and can be run on GIF files in a drive or directory other than the current one. Output is redirectable. GRR will not check files unless they have a .GIF extension - no matter what you specify on the command line. Here is a sample of the output, explanation follows: [start of sample] Filename Filesize Filedate Filetime GIF ver.

GIF version can be either GIF87a or GIF89a (so far, those are the only two versions used). Image data is WIDTH x HEIGHT x COLORS of image. The last column will usually be "GCM/--". The two fields are map/gl: Map can be either GCM or LCM [global or local color map]. GL means that a GIFLITE (tm) header was found, and "--" means one was not found. Since the GIFLITE header can be "erased" by some programs (and can be omitted by the registered version of GIFLITE - so I hear), a GIF file may be compressed by GIFLITE, but GRR will not know it. The GIFLITE header will (probably) not be detected if the GIF version is GIF89a and embedded comments are present.
