NAME
pal2rgb - convert a palette color TIFF image to a full color image
SYNOPSIS
pal2rgb [ options ] input.tif output.tif
DESCRIPTION
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
Options that affect the interpretation of input data are:
-C This option overrides the default behavior of pal2rgb in deter-
mining 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 values.
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 samples 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 compres-
sion. 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 out-
put file. If the -r option is not specified, a number is se-
lected such that each output strip has approximately 8 kilobytes
of data in it.
BUGS
Only 8-bit images are handled.
