pal2rgb - convert a palette color
TIFF image to a full color image
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
Options that affect the interpretation of input data are:
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.
-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:
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.
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
files compression algorithm is used.
Explicitly specify the number of rows in each strip of the
-r option is not specified, a number is selected such that each
output strip has approximately 8 kilobytes of data in it.
Only 8-bit images are handled.
