.TH PAL2RGB 1 "September 20, 2005" "libtiff"
.SH NAME
pal2rgb \- convert a palette color
.SM TIFF
image to a full color image
.SH SYNOPSIS
.B pal2rgb
[
.I options
]
.I input.tif
.I output.tif
.SH DESCRIPTION
.I Pal2rgb
converts a palette color
.SM TIFF
image to a full color image by
applying the colormap of the palette image to each sample
to generate a full color
.SM RGB
image.
.SH OPTIONS
Options that affect the interpretation of input data are:
.TP
.B \-C
This option overrides the default behavior of
.I 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
.SM TIFF
specification) are assumed.
The
.B \-C
option can be used to explicitly specify the number of
bits for colormap entries:
.B "\-C 8"
for 8-bit values, 
.B "\-C 16"
for 16-bit values.
.PP
Options that affect the output file format are:
.TP
.B \-p
Explicitly select the planar configuration used in organizing
data samples in the output image:
.B "\-p contig"
for samples packed contiguously, and
.B "\-p separate"
for samples stored separately.
By default samples are packed.
.TP
.B \-c
Use the specific compression algorithm to encoded image data
in the output file:
.B "\-c packbits"
for Macintosh Packbits,
.B "\-c lzw"
for Lempel-Ziv & Welch,
.B "\-c zip"
for Deflate,
.B "\-c none"
for no compression.
If no compression-related option is specified, the input
file's compression algorithm is used.
.TP
.B \-r
Explicitly specify the number of rows in each strip of the
output file.
If the
.B \-r
option is not specified, a number is selected such that each
output strip has approximately 8 kilobytes of data in it.
.SH BUGS
Only 8-bit images are handled.
