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.
