摘要： A method to perform image transformations is provided. Transformations of an image stored in system memory are carried out by copying the image data, transforming the image data to a selected orientation, and outputting the transformed image for display, printing, or others. Throughout the transformation process, the image stored in system memory remains unchanged in the original orientation (T0-normal transformation). The transformation process is carried out by accessing in predetermined orders/sequences the image data copied from system memory to a frame buffer that is made up of N memory modules and arranged such that image data are stored serially with the image scan lines running the length of the frame buffer like that of a traditional frame buffer but with each memory module capable of being individually accessed. A line stride value S has been specifically derived to control the location of corresponding pixels of N adjacent rows of the image data so that these pixels appear in N different memory modules.
