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
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
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
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.

BUGS

Only 8-bit images are handled.
