In SwivelView 90°, these bits set the vertical coordinates (y) of the PIP
+
window’s top
edge. Increasing y moves the top edge downward in 1 line steps. The vertical coordinates
start at line 0.
Program the PIP
+
Window X Start Position so that
PIP
+
Window X Start Position = y
In SwivelView 180°, these bits set the horizontal coordinates (x) of the PIP
+
window’s
right edge. Increasing x moves the right edge towards the right in steps of (32 ÷ bits-per-
pixel) (see Table 8-2:, “32-bit Address Increments for Color Depth” ). The horizontal
coordinates start at pixel 0.
Program the PIP
+
Window X Start Position so that
PIP
+
Window X Start Position = (panel width - x - 1) ÷ (32 ÷ bits-per-pixel)
Note
Truncate the fractional part of the above equation.
In SwivelView 270°, these bits set the vertical coordinates (y) of the PIP
+
window’s bottom
edge. Increasing y moves the bottom edge downwards in 1 line steps. The vertical coordi-
nates start at line 0.
Program the PIP
+
Window X Start Position so that
PIP
+
Window X Start Position = panel width - y - 1
