## 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 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.
