Rendering an image on a display screen

摘要

Systems and methods for compositing image layers using a GPU shader module. Image layers may be mapped to a destination surface and tiled such that each tile has the same number and kind of mapped image layers. The mapped image layers of a tile may be provided to a shader module, such as a pixel shader, to composite the image layers into display data.

1. A computerized method for rendering an image on a display screen of an electronic display comprising:
receiving, at a processing circuit, a plurality of image layers; mapping the image layers to a destination surface corresponding to pixels of the display screen; determining, by the processing circuit, one or more tiles for the destination surface, wherein each pixel of a respective tile is mapped to a number of image layers; dynamically generating, without user intervention, one or more shader modules for the one or more tiles, each shader module being generated based on the number of image layers and kind of image information within the image layers for at least one of the one or more tiles; utilizing each shader module for tiles associated with a same respective number of image layers containing a respective kind of image information; and providing the display data to the display screen.
