    NAME

    tiff2bw - convert a color
    TIFF
    image to greyscale
     
    

    SYNOPSIS

    tiff2bw [ options ] input.tif output.tif  

    DESCRIPTION

    Tiff2bw converts an RGB or Palette color TIFF image to a greyscale image by combining percentages of the red, green, and blue channels. By default, output samples are created by taking 28% of the red channel, 59% of the green channel, and 11% of the blue channel. To alter these percentages, the -R, -G, and -B options may be used.  

    OPTIONS

    -c
    Specify a compression scheme to use when writing image data: -c none for no compression, -c packbits for the PackBits compression algorithm, -c zip for the Deflate compression algorithm, -c g3 for the CCITT Group 3 compression algorithm, -c g4 for the CCITT Group 4 compression algorithm, and -c lzw for Lempel-Ziv & Welch (the default).
    -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.
    -R
    Specify the percentage of the red channel to use (default 28).
    -G
    Specify the percentage of the green channel to use (default 59).
    -B
    Specify the percentage of the blue channel to use (default 11).
