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 approximately 8 kilobytes.

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