GifHisto
|
|
--------
|
|
|
|
Program to create histogram of number of pixels using each color. Output
|
|
can be formated into a GIF histogram file, or text file - both goes to
|
|
stdout.
|
|
|
|
|
|
Usage:
|
|
------
|
|
|
|
Usage: GifHisto [-q] [-t] [-s Width Height] [-n ImageNumber] [-b] [-h] GifFile
|
|
|
|
If no GifFile is given, GifHisto will try to read stdin for GIF file.

Options:
|
|
--------
|
|
|
|
1. [-q] : quite mode. Default off on MSDOS, on on unix. Controls printout
|
|
of running scan lines. Use -q- to turn off.
|
|
2. [-t] : Force output to be text file of the form: Size of colormap lines
|
|
each contains two integers: number of times color appeared, and color
|
|
index. This in increasing color index order. This output can be fed
|
|
directly to msdos SORT program if number of times color appears ordering
|
|
is desired.
|
|
The colrmap picked is the one to be used for the image to generate
|
|
histogram for, as defined in GIF format.
|
|
3. [-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.
|
|
4. [-n ImageNumber] : Image number to test. Default is one.
|
|
5. [-b] : Zeros the background color count. As only linear scale bars is
|
|
supported and usually the background appears much more times then rest
|
|
of colors, deleting back ground count will improve the scaling of other
|
|
colors.
|
|
6. [-h] : print one command line help, similar to Usage above.
