Figure 16. Blending two layers with a background

3.3.1

Flexible window position and size configuration

Every layer can be positioned and resized at runtime and it must be inside the active display

area. The programmable layer position and size define the first and last visible pixel of a line

and the first and last visible line in the window. It allows to display either the full image (all

the active display area) or only a part of the image frame. Figure 17 shows a small window

where only a portion of the image is displayed while the remaining area is not displayed.

position configuration registers where “x” can refer to layer 1 or layer 2.
