PAL2RGB(1) LibTIFF PAL2RGB(1) NAME pal2rgb - convert a palette color TIFF image to a full color image SYNOPSIS pal2rgb [ options ] input.tif output.tif DESCRIPTION pal2rgb converts a palette color 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 numentries 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 val- ues; 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 planarconfig Explicitly select the planar configuration used in organizing data samples in the output image: -p contig for samples packed contigu- ously, and -p separate for samples stored separately. By default samples are packed. -c compress Use the specified compression algorithm to encoded image data in the output file: -c packbits for Macintosh Packbits, -c lzw for Lem- pel-Ziv & Welch, -c zip for Deflate, -c none for no compression. If no compression-related option is specified, the input file's com- pression algorithm is used. -r striprows 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.
