NAME
biff2pnm - BIFF to Portable Bit/Gray/Pixel Map conversion
SYNTAX
biff2pnm [<option>...] <BIFF-infile> <pnm-outfile>
DESCRIPTION
Read a BIFF-image and convert the first band to one of theformats pbm (portable bitmap), pgm (portable graymap) or ppm(portable pixmap). Write the result to a
pnm-file(pnm: portable anymap).
If the BIFF-image is two-valued, write a pbm-image.If the BIFF-image consists of more than two differentvalues, write a pgm-image.Use option "-rgb" (see below) for rgb images and ppm-format.
The data type of pixelvalue components in pbm/pgm/ppm iseither unsigned char or unsigned short, depending on how thepbm package was compiled. biff2pnmconverts the BIFF band tothe correct pixeltype before conversion to pbm/pgm/ppm. Thepixeltype conversion does not imply any scaling. Values toolarge (or too small) to be represented by the new pixeltype areset to the maximum (or minimum) possible value. A warning isissued to this effect.
User "-" as filename arguments for stdin and stdout.
