Programmable Blanking, Write - Barco Projector User Manual

Notes :
- The calculations are made starting from an imaginary
solid shape as large as the lcd panel.
- To combine several shapes, just put the data of the
requested shapes after each other. The order in which the
shapes are drawn is the same as the order in which they are
sent to the projector.
- The values of the coordinates have to be checked by the
computer !!! Extreme large coordinates can lead to
microprocessor reset.
- "Solid shape" means blanked inside the shape;
- "Hole shape" means no blanking inside the shape.
- The first pixel on the screen (top/left) has coordinate
(0,0).
Example :
Draw following blanking pattern on a projector with
address \x01.
- hole circle (x=350, y=250, r=200)
- solid rectangle (x1=300, y1=200, x2=400, y2=300)
