<H2>DESCRIPTION</H2>
<I>Pal2rgb</I>
converts a palette color
<FONT SIZE="-1">TIFF</FONT>
image to a full color image by
applying the colormap of the palette image to each sample
to generate a full color
<FONT SIZE="-1">RGB</FONT>
image.
<A NAME="lbAE">&nbsp;</A>
<H2>OPTIONS</H2>
Options that affect the interpretation of input data are:
<DL COMPACT>
<DT><B>-C</B>
<DD>
This option overrides the default behaviour of
<I>pal2rgb</I>
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
<FONT SIZE="-1">TIFF</FONT>
specification) are assumed.
The
<B>-C</B>
option can be used to explicitly specify the number of
bits for colormap entries:
<B>-C 8</B>
for 8-bit values,
<B>-C 16</B>
for 16-bit values.
</DL>
<P>
Options that affect the output file format are:
<DL COMPACT>
<DT><B>-p</B>
<DD>
Explicitly select the planar configuration used in organizing
data samples in the output image:
<B>-p contig</B>
for samples packed contiguously, and
<B>-p separate</B>
for samples stored separately.
By default samples are packed.
<DT><B>-c</B>
<DD>
Use the specific compression algorithm to encoded image data
in the output file:
<B>-c packbits</B>
for Macintosh Packbits,
<B>-c lzw</B>
for Lempel-Ziv &amp; Welch,
<B>-c zip</B>
for Deflate,
<B>-c none</B>
for no compression.
If no compression-related option is specified, the input
file's compression algorithm is used.
<DT><B>-r</B>
<DD>
Explicitly specify the number of rows in each strip of the
output file.
If the
<B>-r</B>
option is not specified, a number is selected such that each
output strip has approximately 8 kilobytes of data in it.

<H2>BUGS</H2>
Only 8-bit images are handled.
