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.
