vccvt − Format conversion for color map images

vccvt [if=infile] [of=ofile] [lf=lutfile] [-a] [-g] [-l] [-i]

Vccvt Performs format conversions of images with color maps. By default vccvt converts the specified image to a color map format. If no color map is specified then one is generated; in this case the image must not contain more than 256 unique colors. If a color map is specified then the best match for each truecolor pixel is found. The match criteria is very simple and slow, in general it is better to use vccode when there is not an exact color match.

Input must be a truecolor image or image sequence except when the -i option is specified.

lf=file

This option specifies a color map file, The resulting image will be encoded with the given color map.

-a

Autoscale the color map so the "brightest" entry is 255.

-g

Delete the color map information from a colormap file. The images are output in byte format with no modifications to the pixel values.

-l

Extract any color maps from a color map image file. All color maps found in the file are output in sequence.

-i

Inverse transform. Color map images are converted to truecolor format.
