20130039601Method and Apparatus for Managing Image-Processing Operations - Embodiments of the present invention provide a system for performing image conversion operations. The system starts by receiving a request from a client for one or more pixel buffers containing a pixel-formatted, cropped, geometrically transformed, and/or color matched version of an image representation.
