SYNOPSIS

pal2rgb [ options ] input.tif

DESCRIPTION

       cols="2" cellspacing="0" cellpadding="0">

Pal2rgb converts a palette color

<small>TIFF</small> image to a full color image by applying

the colormap of the palette image to each sample to generate

a full color <small>RGB</small> image.

OPTIONS

       cols="2" cellspacing="0" cellpadding="0">

Options that affect the interpretation of input data

are:

       cols="5" cellspacing="0" cellpadding="0">

−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

<small>TIFF</small> 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:

       cols="5" cellspacing="0" cellpadding="0">

−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

       cols="2" cellspacing="0" cellpadding="0">

Only 8-bit images are handled.
