An apparatus, method, and computer program product for scaling a rendered surface. The apparatus includes a graphics processor configured to render a surface at a source resolution, wherein a scaling parameter is associated with the surface, the scaling parameter defining the source resolution and a destination resolution. The apparatus further includes a display processor configured to scale the rendered surface to the destination resolution. Preferably, the scaling parameters are EGL surface attributes.

Post-render graphics scaling

In general, the present disclosure describes various techniques for programmable, pattern-based unpacking and packing of data channel information, including still image, video, and audio component data. One example device comprises a programmable processor having a plurality of processing pipelines. The processor is configured to receive pattern information that specifies a pattern for a plurality of input data components, the pattern information comprising a plurality of pattern elements that are each associated with one or more of the input data components, and each input data component being selected from a component group consisting of a still image data component, an audio data component, and a video data component. For example, the input data components may comprise pixel data components, such as color channels. The processor is further configured to provide each input data component to a selected processing pipeline of the processor in accordance with the pattern information.
