-.SH NAME
-tiffmedian \- apply the median cut algorithm to data in a
-.SM TIFF
-file
-.SH SYNOPSIS
-.B tiffmedian
-[
-.I options
-]
-.I input.tif
-.I output.tif
-.SH DESCRIPTION
-.I tiffmedian
-applies the median cut algorithm to an
-.SM RGB
-image in
-.I input.tif
-to generate a palette image that is written to
-.IR 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.
-.SH OPTIONS
-.TP
-.B \-c
-Specify the compression to use for data written to the output file:
-.B none
-for no compression,
-.B packbits
-for PackBits compression,
-.B lzw
-for Lempel-Ziv & Welch compression,
-and
-.B zip
-for Deflate compression.
-By default
-.I tiffmedian
-will compress data according to the value of the
-.I Compression
-tag found in the source file.
-.IP
-.SM LZW
-compression can be specified together with a
-.I 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.
-.B "\-c lzw:2"
-for
-.SM LZW
-compression with horizontal differencing.
-.TP
-.B \-C
-Specify the number of entries to use in the generated colormap.
-By default all 256 entries/colors are used.
-.TP
-.B \-f
-Apply Floyd-Steinberg dithering before selecting a colormap entry.
-.TP
-.B \-r
-Specify the number of rows (scanlines) in each strip of data
-written to the output file.
-By default,
-.I tiffmedian
-attempts to set the rows/strip
-that no more than 8 kilobytes of data appear in a strip.
-.SH NOTES
-This program is derived from Paul Heckbert's
-.I median
-program.
