getgmr - Restore an RLE image to a Grinnell GMR-27 frame buffer.
getgmr
[ -q ] [ -d ] [ -{BO} ] [ -{pP} x y ] [ -c channel [ into ] ] [ infile ]
Displays
an RLE(5)
file on a Grinnell GMR-27 frame buffer.
- -q
- Query the given file.
Determine if it is an RLE(5)
file. Does not affect the frame buffer.
- -D
- Debug the given file. Print information about each command in the input
file. Displays as it prints.
- -B
- If the file was saved with -B or -O, restore
the background color before restoring the image data.
- -O
- If the file was
saved with -B or -O, restore the image data in overlay mode. Only areas of
the original image which were not the background color are restored. The
rest of the image already in the frame buffer is undisturbed.
- -p x y
- Reposition
the image. The original lower left corner is positioned at [x, y] before
restoring the image. A warning: A saved image should not be repositioned
so that any saved data wraps around the X borders. If the file was not
saved with -B or -O, this includes background areas.
- -P x y
- Reposition the image
incrementally, that is, x and y are taken as offsets from the original
position of the image.
- -c channel [ into ]
- Put only the given color channel
into the frame buffer. If into is specified, loads it into that channel.
If the input file is black and white (one channel), then -c channel is equivalent
to -c 0 channel.
- infile
- Name of file to display. If not specified, input
is read from stdin.

to interact poorly with Grinnell hardware bugs at times.
