pal2rgb - convert a palette color TIFF image to a full color image
pal2rgb [options] input.tif output.tif
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.
The following input data options are supported:
-C Override the default behavior of pal2rgb to determine 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.
The following output file options are supported:
-c Specify a compression scheme to use when writing image data:
-c lzw Lempel-Ziv and Welch algorithm.
-c none No compression.
-c packbits PackBits compression algorithm.
-c zip Deflate compression algorithm.
If no compression-related option is specified, the input-file compression algorithm is used.
-p Explicitly select the planar configuration used to organize data samples in the output image:
-p contig Samples are packed contiguously. This is the default.
-p separate Samples are stored separately.
-r Write data with a specified number of rows per strip. By default, the number of rows per strip is selected so that each strip is approximately 8 kilobytes.
The following operands are supported:
input.tif The name of the input TIFF file.
output.tif The name of the output file.
