VRTIMG

Merges a virtual graphic with an AREA. (Command being sunset)

VRTIMG virt area width line ele <keywords>

virt	virtual graphics number; the range is 1-9999 (default=none)
area	destination area number(default=none)
width	graphics line width in pixels; the range is 1-64 (default=1)
line	number of lines used when creating area (default=480)
ele	number of elements used when creating area (default=640)

LEV=

area brightness values for corresponding graphics color levels (default=15,31,47,63,79,95,111,127,143,159,175,191,207,223,239,255)

VRTIMG writes virtual graphics to an AREA by converting the graphics color levels in virt to corresponding brightness values in the AREA.

If the AREA does not exist, it is created; otherwise, the AREA must have the following characteristics:

-- 1 byte data -- single band -- no more than 5000 elements/line -- calibration type must be visible brightness (BRIT)
When specifying values with the LEV keyword, the first value corresponds to the brightness value that graphics color level 1 will be assigned in the AREA, the second value corresponds to the brightness value for graphics color level 2, etc.
