摘要
A method, comprising determining parameters for a first window and a second window on a display screen, said first window superimposed in front of the second window. The method further comprises determining which areas of the second window are not superimposed by the first window and dividing the areas into multiple portions, each portion abutting a separate side of the first window. For each of the portions, the method comprises fetching pixel data from a memory using an addressing mode suitable for said portion and displaying said pixel data on the display screen.
