Image Display Handler (DSP)

Long name Video Display
Short name DSP

On Unix systems it is possible to access the display as if it were a file, via the GDB library. Possible file names that would refer to the display are "VD00", "VD0:", "VD1:", "VD2:", or "VD3:".

It is possible to access the image planes of the display as channels, graphic planes as bitmaps, and vector layers as vector segments. The LUTs and PCTs are also accessible. The overall georeferencing (in the manner of Set Map Area) is also accessible.

Note: The old Handler does not support georeferencing or vector layers.
