getap - get RLE images to an Apollo display
getap [ -b ] [
-g gamma ] [ -l ] [ -n ] [ -r ] [ -t text ] [ -w ] [ -x left ] [ -y top ] [ file
]
This program displays an RLE(5)
file on an Apollo workstations
running the Display Manager. It uses a dithering technique to take a full-color
or gray scale image into the limited number of colors typically available,
unless "borrow mode" is specified. Under borrow mode, the 24 bit mode of
the Apollo hardware is used (if it's available). On bitmap displays, getap
converts the image to black and white and uses bitmap dithering.
- -b
- This tells getap to use "borrow mode" instead of an apollo window, if the
hardware supports it. The only hardware that supports this are the DN550,
DN560 and the DN660. The bottom portion of the image is chopped off on
workstations without square screens.
- -g gamma
- This loads a color map with
the specified gamma.
- -l
- Loads a linear color map.
- -n
- "No border" mode. The
Apollo window will have no border or annotation drawn.
- -r
- On black and white
displays, this flips the orientation of black and white.
- -t text
- Displays
the text string at the bottom of the image.
- -w
- Convert the image to grays
before displaying. On 4-bit displays, this produces a significantly nicer
looking image.
- -x left
- Specify position of the left edge of the window.
- -y
top
- Specify position of the top edge of the window.

Getap is pretty sloppy about dealing with the
color map, particularly in window mode.
Since Apollo workstations now support
the X window system, getap is mostly subsumed by getx11.
