rgb2ycbcr - Unix, Linux Command
rgb2ycbcr - convert non-YCbCr
TIFF images to a YCbCr
src1.tif src2.tif ... dst.tif
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
Output data are compressed with the
PackBits compression scheme, by default; an alternate scheme can be selected with the
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;
-r option can be used to explicitly set the number of
rows per strip.
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,
-c lzw for Lempel-Ziv & Welch.
Set the horizontal sampling dimension to one of: 1, 2 (default), or 4.
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.
Set the vertical sampling dimension to one of: 1, 2 (default), or 4.
