NAME
rgb2ycbcr - convert non-YCbCr TIFF images to a YCbCr TIFF image
SYNOPSIS
rgb2ycbcr [ options ] src1.tif src2.tif ... dst.tif
DESCRIPTION
rgb2ycbcr converts RGB color, greyscale, or bi-level TIFF images to YCbCr images by transforming and sampling pixel data. If multiple files are specified on the command line each source file is converted to a separate directory in the destination file. By default, chrominance samples are created by sampling 2 by 2 blocks of luminance values; this can be changed with the -h and -v options. Output data are compressed with the PackBits compression scheme, by default; an alternate scheme can be selected with the -c option. By default, output data are compressed in strips with the number of rows in each strip selected so that the size of a strip is never more than 8 kilobytes; the -r option can be used to explicitly set the number of rows per strip.
OPTIONS
-c Specify a compression scheme to use when writing image data: -c none for no compression, -c packbits for the PackBits compression algorithm (the default), -c jpeg for the JPEG compression algorithm, -c zip for the deflate compression algorithm, and -c lzw for Lempel-Ziv & Welch. -h Set the horizontal sampling dimension to one of: 1, 2 (default), or 4. -r Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approxi- mately 8 kilobytes. -v Set the vertical sampling dimension to one of: 1, 2 (default), or 4.
