Abstract
The described embodiments comprise a system that adjusts pixel values to produce visual effects in a frame to be displayed. During operation, the system receives coordinates and pixel-adjustment values for one or more control points within the frame. Next, the system calculates pixel-adjustment values for pixels in the frame based on the coordinates and the pixel-adjustment values for the one or more control points. The system then applies the pixel-adjustment values to the pixels within the frame and displays the frame.
