rgb2ycbcr - convert non-YCbCrTIFF
images to a YCbCrTIFF
]src1.tif src2.tif ... dst.tif
color, greyscale, or bi-levelTIFF
images to YCbCr images by transforming and sampling pixel data. If multiplefiles are specified on the command line each source file is converted to aseparate directory in the destination file.
By default, chrominance samples are created by sampling2 by 2 blocks of luminance values; this can be changed with the-hand-voptions.Output data are compressed with thePackBitscompression scheme, by default; an alternate scheme can be selected with the-coption.By default, output data are compressed in strips withthe number of rows in each strip selected so that thesize of a strip is never more than 8 kilobytes;the-roption can be used to explicitly set the number ofrows per strip.
- Specify a compression scheme to use when writing image data:-c nonefor no compression,-c packbitsfor the PackBits compression algorithm (the default),-c jpegfor the JPEG compression algorithm,-c zipfor the deflate compression algorithm,and-c lzwfor 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 stripis approximately 8 kilobytes.
- Set the vertical sampling dimension to one of: 1, 2 (default), or 4.
