|

|
|
||
|
|
<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.

|
|
<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 & 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.
