RGB2YCBCR(1)						      General Commands Manual						      RGB2YCBCR(1)

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.
