VRTIMG

Command being sunset.

Merges a virtual graphic with an AREA

Format

VRTIMG virt area width line ele <keywords>

Parameters

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)

Keyword

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)

Remarks:

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.
