9.2.6 Move BitBLT in Negative Direction with ROP

Note
8. Program the BitBLT Destination/Source Linear Select bits for a rectangular BitBLT
The Move BitBLT in Negative Direction with ROP is similar to the Move BitBLT in
Positive direction. Use this BitBLT operation when the source and destination BitBLT
areas overlap and the destination address is greater then the source address. Refer to Figure
9-1: on page 76 to see when to make the decision to switch to the Move BitBLT in a
Positive direction.
When using the Move BitBLT in Negative Direction it is necessary to calculate the
addresses of the last pixels as opposed to the first pixels. This means calculating the
addresses of the lower right corners as opposed to the upper left corners.
Example 13: Copy a 9 x 101 rectangle at the screen coordinates x = 100, y = 10 to
In the following example, the coordinates of the source and destination rectangles inten-
tionally overlap.
1. Calculate the source and destination addresses (lower right corners of the source and
The sequence of register setup is irrelevant as long as all required registers are pro-
grammed before the BitBLT is started.
(BitBLT Destination Linear Select = 0, BitBLT Source Linear Select = 0).
