摘要： A method for tile-based rendering of content. Content may be rendered in a memory region organized as multiple tiles. In scenarios in which content is generated in layers, for operations that involve compositing image layers, an order in which portions of the image are processed may be selected to reduce the aggregate number of memory accesses times, which in turn may improve the performance of a computer that uses tile-based rendering. An image may be processed such that operations relating to rendering portions of different layers corresponding to the same tile are performed sequentially. Such processing may be used in a computer with a graphics processing unit that supports tile-based rendering, and may be particularly well suited for computers with a slate form factor. An interface to a graphics processing utility within the computer may provide a flag to allow an application to specify whether operations may be reordered.

摘要： Methods, systems, and computer-storage media for target independent rasterization of an image. The target is the memory allocated for a rendered image within a graphics pipeline. Embodiments of the present invention allow the rasterization process's sampling rate to be specified independently from the memory allocated for the rendered image. Embodiments of the present invention also allow the rasterization process to be executed at a rate that does not correspond to the memory allocated for the rendered target.

摘要： Virtual surface update and composition techniques are described. These techniques support the use of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, use of surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and use of occlusion management techniques.

摘要： Various embodiments provide techniques for enabling multiple graphics interfaces to be accessed to perform graphics-related operations. In at least some embodiments, techniques determine if the multiple graphics interfaces can share a memory resource for performing graphics operations. If the multiple graphics interfaces can share the memory resource, a coalescing graphics element is provided that can be used by applications to perform multiple graphics operations.

摘要： A method for text rendering that is well suited for use in a computing device with a high resolution display but a low-power graphics processing unit (GPU). The method may comprise calculating a coverage representation of the text in a format that can be efficiently processed by the GPU. As a result, the GPU may perform anti-aliasing and subsequent operations in the rendering process. Efficient processing may be achieved by providing the coverage representation in a format that allows values associated with pixels to be computed based on a byte-aligned chunk of bits in the coverage representation. Additionally, processing on the chunks may be performed using at least one lookup table. For large filtering kernels used for anti-aliasing, the lookup tables may be partitioned into portions dependent on dynamic text characteristics and those independent of the dynamic text characteristics.
