NAME

       raw2gif	-  A  program to convert RAW image data into GIF files.  Only one image can be handled.  The RAW image file is assumed to hold one
       pixel color in one byte, and therefore the file size must be Width times Height as specified by the -s option below.

USAGE

       raw2gif [-q] -s Width Height [-p ColorMapFile] [-h] RawFile

       If no RawFile is given, Raw2Gif will try to read RAW data from stdin.  The generated GIF File is dumped to stdout.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

	       Quiet mode.  Defaults off on MSDOS, on under UNIX.  Controls printout of running scan lines. Use -q- to invert.

       -s Width Height

	       the dimensions of the image MUST be specified in the command line.  The RAW image file size must  be  exactly  Width  times  Height
	      bytes (each byte is one pixel color).

       [-p ColorMapFile]

	       Color  map  to  load  for  given RAW image.  This file has 4 integers in line (ColorIndex Red Green Blue), and the ColorIndex is in
	      order starting from 1. See GifClrMp, which can also use/create these bitmap files. If no color map is specified,	uses  the  EGA	16
	      color pallete as default color map.

       [-h]

	       Print one line of command line help, similar to Usage above.

gifhisto(1)						      General Commands Manual						       gifhisto(1)

NAME

       gifhisto  -  A program to create histogram of number of pixels using each color.  The output can be formatted into a GIF histogram file, or
       as text file - both go to stdout.

USAGE

       gifhisto [-q] [-t] [-s Width Height] [-n ImageNumber] [-b] [-h] gif-file

       If no gif-file is given, GifHisto will try to read a GIF file from stdin.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

	       Quiet mode.  Default off on MSDOS, on under UNIX. Controls printout of running scan lines.  Use -q- to invert.

       [-t]

	       Force output to be text file of the following form: (colormap size) lines each containing  two  integers:  number  of  times  color
	      appeared, and color index.  Lines are in increasing color index order. This output can be fed directly to a sort program if ordering
	      by color frequency is desired.

	      The colrmap picked is the one to be used for the image to generate histogram for, as defined in GIF format.

       [-s Width Height]

	       Size of GIF histogram file.  The Height of the histogram should be power of 2 dividable by number of colors in colormap.

	      Width sets the resolution (accuracy if you like) of the histogram as the maximum histogram bar is scaled to fit it.

       [-n ImageNumber]

	       Image number to test.  Default is one.

       [-b]

	       Zeros the background color count.  As only linear scale bars are supported and usually the background appears much more often  then
	      other colors, deleting the background count will improve the scaling of other colors.

       [-h]

	       Print one line of command line help, similar to Usage above.
