In SwivelView 0°
, these registers set the vertical coordinates (y) of the sub-windows’s top
left corner. Increasing values of y move the top left corner downwards in steps of 1 line.
Program the Sub-Window Y Start Position registers so that
sub-window Y start position registers = y
In SwivelView 90°
, these registers set the horizontal coordinates (x) of the sub-window’s
top right corner. Increasing values of x move the top right corner towards the right in steps
of 32
÷
bits-per-pixel (see Table 8-2: )
Program the Sub-Window Y Start Position registers so that
sub-window Y start position registers = (panel height - x)
÷
(32
÷
bits-per-pixel)
Note
panel height - x must be a multiple of 32
÷
bits-per-pixel.
In SwivelView 180°
, these registers set the vertical coordinates (y) of the sub-window’s
bottom right corner. Increasing values of y move the bottom right corner downwards in
steps of 1 line.
Program the Sub-Window Y Start Position registers so that
sub-window Y start position registers = panel height - y
In SwivelView 270°
, these registers set the horizontal coordinates (x) of the sub-window’s
bottom left corner. Increasing values of x move the bottom left corner towards the right in
steps of 32
