Abstract: In various embodiments, systems and methods are provided for using an expanded image format to facilitate image transformations. The expanded image format can include at least a first set of boundaries and a second set of boundaries. The first set of boundaries corresponds to the image for transform, while the second set of boundaries provide a region beyond the image that can assist a graphics processing unit with performing a transform. Optionally, the expanded information can also include pixel value information for pixels in the region between the image boundary and the overboundary.

Abstract: Mipmaps are used to optimize image rendering by intelligently determining which generated mipmaps can be reused and then storing the reusable mipmaps in cache for quick retrieval later. A graphic transformation application (GTA) working with or executed by a graphics processing unit (GPU) identifies images to be rendered on a screen and effects to be applied such images. Transforms to carry out the effects are charged with generating mipmaps of the images, and the GTA monitors the generated mipmaps and images to be rendered to determine what mipmaps to cache for future transforms.
