# pal2rgb(1)

convert a palette color TIFF image to a full color image

## 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 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 planarconfig**

  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 compress**

  Use the specified 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 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.
