.SH DESCRIPTION
.I 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
.BR -c ,
which produces output suitable for a color PostScript printer.
Option
.B -h
sets the output image height in inches.  The default height is 3", to match
the default height of the
.B .BP
macro in
.BR "troff -mpictures" .
.PP
.I 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 \(em use
the
.B -l
flag or
.IR quantize (9.1)
or some other dithering filter to reduce color images to a single channel.
Option
.B -i
produces an interlaced output file.
Option
.B -b
sets the number of bits per pixel in the output file.
The default is 8, which is the maximum.
Option
.B -l
makes
.I pic2gif
compute the NTSC luminance of its input.
If
.IR pic2gif 's
input contains no color map, it assumes that it is a 256 grey shade monochrome image.
