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 encapsu‐
lated PostScript, writing the result to standard output. If the input
image is full-color, its luminance is computed first, except under op‐
tion -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 -mpic‐
tures.
Pic2gif converts its input image (default standard input) into a Com‐
puserv GIF format file, writing the result to standard output. It con‐
verts 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 fil‐
ter 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.
