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 LZW 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 kilo‐
       bytes; 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  compres‐
	      sion  algorithm, -c jpeg for the JPEG compression algorithm, and
	      -c lzw for Lempel-Ziv & Welch (the default).

       -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
	      approximately 8 kilobytes.

       -v     Set  the	vertical sampling dimension to one of: 1, 2 (default),
	      or 4.
