System and method for improving visual appearance of efficient rotation algorithm

A computer-readable medium that includes computer-executable instructions for ordering operations for graphical hardware characteristics, the instructions comprising:

• identifying the graphical hardware characteristics;
• determining a source image orientation;
• determining a target image orientation;
• identifying a block manipulation algorithm;
• and
• evaluating at least one of the identified graphical hardware characteristics, the source image orientation, the target image orientation, and the block manipulation algorithm to determine a new write order for the block manipulation algorithm.

The computer-readable medium of claim 11, wherein the new write order for the block manipulation algorithm comprises:

• if a vertical trace of a target display device scans the complete target display device from left to right, writing the target image pixel-by-pixel starting at top left corner ending at bottom right corner from left to right;
• if a vertical trace of a target display device scans the complete target display device from right to left, writing the target image pixel-by-pixel starting at top right corner ending at bottom left corner from right to left;
• and
• if a vertical trace of a target display device scans the target display device in a predetermined number of horizontal bands from left to right, writing the target image pixel-by-pixel starting at top left corner ending at bottom right corner from left to right in the predetermined number of horizontal bands.
