System level graphics manipulations on protected content

At least certain embodiments of the present disclosure include a method to manipulate graphics with protected content. In some embodiments, a composite engine of a computing system retrieves data within a region within a frame buffer holding pixels of an image displayed on a display device of the computing system. The region corresponds to an area of interest within the image, and the data retrieved includes pixels forming a portion of the image in the area of interest and protected content associated with the image. The composite engine may re-composite the area of interest with the pixels retrieved to produce an enlarged version of the portion of the image in the area of interest, without exposing the protected content to applications outside of the window server.
