Drawing an image with transparent regions on top of another image without using an alpha channel
TLDR
In this article, an image display system draws a first image on top of a second image using the transparency information encoded in the color channels of the pixels to obtain a combined image.Abstract:
An image display system draws a first image on top of a second image. Pixels of the first image include one or more color channels which encode color information, but do not include an alpha channel which encodes transparency information. The system encodes transparency information for the pixels in the first image using at least one bit in at least one color channel of each pixel. The system draws the first image on top of the second image using the transparency information encoded in the color channels of the pixels to obtain a combined image.read more
