摘要

System and method for using image data of non alpha channel environment of a perception of the alpha channel.This is an image produced by an application of the perception of non alpha channel which is used in an environment of perception of the alpha channel.The data file of a pixel to be written by the application of the perception of non alpha channel is initialized by setting alpha value for each pixel to 1.The application of perception of the alpha channel then writes to the initialized pixel data file, by changing some or all pixel data.The alpha value for each pixel is then decreased to 1 (modulo 256) becoming opaque the pixels changed, and transparent pixels unchanged.
