pal2rgb - convert a palette color TIFF image to a full color image pal2rgb [ options ] input.tif output.tif 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 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.

Only 8-bit images are handled. tiffinfo (1), tiffcp (1), tiffmedian (1), libtiff (3)
