Background: The error message returned when the etc1 image format is invalid. The alpha channel is not supported. As a result, programmers waste some effort on alpha channel processing. In order to use etc1, and some transparency effects must have alpha channels, the general processing method is to separate RGB and alpha into two images for storage. Only images with Alpha channels and RGB Images are the alp
