Image processing using bounds adjustment
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.
