NAME

pic2ps, pic2gif - convert picture files to other formats

SYNOPSIS

fb/pic2ps [ -c ] [ -h height ] [ input ]

fb/pic2gif [ -i ] [ -l ] [ -b depth ] [ input ]

DESCRIPTION

Pic2ps converts its input image (default standard input) into encapsulated PostScript, writing the result to standard output. If the input image is full-color, its luminance is computed first, except under option -c, which produces output suitable for a color PostScript printer. Option -h sets the output image height in inches. The default height is 3", to match the default height of the .BP macro in troff -mpictures.

Pic2gif converts its input image (default standard input) into a Compuserv GIF format file, writing the result to standard output. It converts only the first channel of the input image, which may yield wrong results ­ use the -l flag or quantize(9.1) or some other dithering filter to reduce color images to a single channel. Option -i produces an interlaced output file. Option -b sets the number of bits per pixel in the output file. The default is 8, which is the maximum. Option -l makes pic2gif compute the NTSC luminance of its input. If pic2gif's input contains no color map, it assumes that it is a 256 grey shade monochrome image.
