Abstract:
1. A method comprising: scanning a first row of a display plane, the first display plane being part of a multi-plane display; determining, by a processor, that the first row of the display plane includes a non-transparent pixel; indicating the first row has a non-transparent pixel by adding the entire first row to a first bounding rectangle; scanning a second row of the display plane, wherein the second row is subsequent and adjacent to the first row; determining that the second row includes a non-transparent pixel; adding the entire second row to the first bounding rectangle; scanning a third row of the display plane, wherein the third row is subsequent to the second row; determining that the third row does not include a non-transparent pixel; arranging for the third row to not be added to any bounding rectangle; scanning a fourth row of the display plane, wherein the fourth row is subsequent to the third row; determining that the fourth row includes a non-transparent pixel; adding the entire fourth row to a second bounding rectangle; and compositing, by the processor, rows of the of the display plane within the first and second bounding rectangles with corresponding rows in another plane, wherein rows not within the first and second bounding rectangles are not composited with corresponding rows in the other plane.
