lcdif_porter_duff
Overview
This example demonstrates how to use the LCDIF alpha blend function to perform the Porter Duff compositing. In this example, a red rectangle of overlay layer 0 is in the top left corner of the panel as source surface, and a blue rectangle of the video/graphic layer is at the bottom right position of the red one as destination surface. Every Porter Duff mode result is shown for 2 seconds, then switch to the next mode.
