C44 --- DjVuLibre-3.5.27 Image compression utility using IW44 wavelets Usage: c44 [options] pnm-or-jpeg-file [djvufile] Options: -slice n+...+n -- select an increasing sequence of data slices expressed as integers ranging from 1 to 140. -bpp n,..,n -- select a increasing sequence of bitrates for building progressive file (in bits per pixel). -size n,..,n -- select an increasing sequence of minimal sizes for building progressive files (expressed in bytes). -percent n,..,n -- selects the percentage of original file size for building progressive file. -decibel n,..,n -- select an increasing sequence of luminance error expressed as decibels (ranging from 16 to 50). -dbfrac frac -- restrict decibel estimation to a fraction of the most misrepresented 32x32 blocks -mask pbmfile -- select bitmask specifying image zone to encode with minimal bitrate. (default none) -dpi n -- sets the image resolution -gamma n -- sets the image gamma correction -crcbfull -- encode chrominance with highest quality -crcbnormal -- encode chrominance with normal resolution (default) -crcbhalf -- encode chrominance with half resolution -crcbnone -- do not encode chrominance at all -crcbdelay n -- select chrominance coding delay (default 10) for -crcbnormal and -crcbhalf modes
