NAME
pal2rgb - convert a palette color TIFF image to a full color imageSYNOPSIS
pal2rgb [ options ] input.tif output.tifDESCRIPTION
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.SEE ALSO
