pal2rgb - convert a palette color TIFF image to a full color image
pal2rgb [ options ] input.tif output.tif
Pal2rgb converts a palette color TIFF image to a full color image by applying the colormap
of the palette image to each sample to generate a full color RGB image.
Options that affect the interpretation of input data are:
-C This option overrides the default behaviour of pal2rgb in determining whether or
not colormap entries contain 16-bit or 8-bit values. By default the colormap is
inspected and if no colormap entry greater than 255 is found, the colormap is
assumed to have only 8-bit values; otherwise 16-bit values (as required by the TIFF
specification) are assumed. The -C option can be used to explicitly specify the
number of bits for colormap entries: -C 8 for 8-bit values, -C 16 for 16-bit val-
Options that affect the output file format are:
-p Explicitly select the planar configuration used in organizing data samples in the
output image: -p contig for samples packed contiguously, and -p separate for sam-
ples stored separately. By default samples are packed.
-c Use the specific compression algorithm to encoded image data in the output file: -c
packbits for Macintosh Packbits, -c lzw for Lempel-Ziv & Welch, -c zip for Deflate,
-c none for no compression. If no compression-related option is specified, the
input file's compression algorithm is used.
-r Explicitly specify the number of rows in each strip of the output file. If the -r
option is not specified, a number is selected such that each output strip has
approximately 8 kilobytes of data in it.
Only 8-bit images are handled.
