PROGRAM:
NAME
tiffmedian - apply the median cut algorithm to data in a TIFF file
SYNOPSIS
tiffmedian [ options ] input.tif output.tif
DESCRIPTION
tiffmedian applies the median cut algorithm to an RGB image in input.tif to generate a
palette image that is written to output.tif. The generated colormap has, by default, 256
entries. The image data is quantized by mapping each pixel to the closest color values in
the colormap.
OPTIONS
-c Specify the compression to use for data written to the output file: none for no
compression, packbits for PackBits compression, lzw for Lempel-Ziv & Welch
compression, and zip for Deflate compression. By default tiffmedian will compress
data according to the value of the Compression tag found in the source file.
LZW compression can be specified together with a predictor value. A predictor
value of 2 causes each scanline of the output image to undergo horizontal
differencing before it is encoded; a value of 1 forces each scanline to be encoded
without differencing. LZW-specific options are specified by appending a
``:''-separated list to the ``lzw'' option; e.g. -c lzw:2 for LZW compression with
horizontal differencing.
-C Specify the number of entries to use in the generated colormap. By default all 256
entries/colors are used.
-f Apply Floyd-Steinberg dithering before selecting a colormap entry.
-r Specify the number of rows (scanlines) in each strip of data written to the output
file. By default, tiffmedian attempts to set the rows/strip that no more than 8
kilobytes of data appear in a strip.
NOTES
This program is derived from Paul Heckbert's median program.
