12 Pal2rgb converts a palette color TIFF image to a full color image by
13 applying the colormap of the palette image to each sample to generate a
14 full color RGB image.

17 Options that affect the interpretation of input data are:
18
19 -C This option overrides the default behavior of pal2rgb in deter‐
20 mining whether or not colormap entries contain 16-bit or 8-bit
21 values. By default the colormap is inspected and if no colormap
22 entry greater than 255 is found, the colormap is assumed to have
23 only 8-bit values; otherwise 16-bit values (as required by the
24 TIFF specification) are assumed. The -C option can be used to
25 explicitly specify the number of bits for colormap entries: -C 8
26 for 8-bit values, -C 16 for 16-bit values.
27
28 Options that affect the output file format are:
29
30 -p Explicitly select the planar configuration used in organizing
31 data samples in the output image: -p contig for samples packed
32 contiguously, and -p separate for samples stored separately. By
33 default samples are packed.
34
35 -c Use the specific compression algorithm to encoded image data in
36 the output file: -c packbits for Macintosh Packbits, -c lzw for
37 Lempel-Ziv & Welch, -c zip for Deflate, -c none for no compres‐
38 sion. If no compression-related option is specified, the input
39 file's compression algorithm is used.
40
41 -r Explicitly specify the number of rows in each strip of the out‐
42 put file. If the -r option is not specified, a number is
43 selected such that each output strip has approximately 8 kilo‐
44 bytes of data in it.
45
47 Only 8-bit images are handled.
