Name
sun-pix — convert Sun bitmaps from screendump(1) into pix(5) or bw(5) raster image
DESCRIPTION
sun-pix
is a program to take Sun bitmap files created with Sun's
screendump(1)
command, and convert them to a
pix(5)
format file. If the
-b
flag is specified, a
bw(5)
format file is created instead. Note that
sun-pix
will refuse to write to a terminal; its output must be redirected unless it's invoked with the
-H
flag. The dimensions of the input file are the dimensions of the output
file, and use of the
-H
flag will cause the image size to be printed without further
processing of the input, or generation of any other output;
the image size is output as a pair
of command line options (i.e., -w1152 -n900) suitable
for use with other
brlcad(1)
tools such as
pix-fb(1).
When the
-v
flag is specified, all the fields of the header are printed on stderr,
to aid debugging. Note that the "encoded" format is not supported.
Specifying the
-i
flag will invert the sense of a one-bit wide input image, i.e.,
exchanging black for white. The default Sun image is black print on
white background; the
-i
flag will give a white image on black background, which is often better
for purposes of creating overlays to be composited with
pixmerge(1)
on top of color images.
The
-P
flag indicates that the input is a pure bitmap with no Sun-style header
on it. The first bit to be processed will be the most significant bit (MSB),
i.e., the left-most bit in the byte.
The
-C
flag indicates that the color map is to be output.
Note that the input file is expected to be in Sun ("network") byte order (i.e., "big-endian", with byte 0 on the left), regardless of the byte order of the machine running this program.
