Abstract
Techniques for a compressed image with alpha channel data are described. Encoded alpha channel data from a compressed image representation may be extracted. A common type pixel run characteristic may be determined for at least one common type pixel run represented in the encoded alpha channel data. A common alpha channel value is applied, based on the common type pixel run characteristic, to pixels in a decompressed image representation correlated to the at least one common type pixel run. Pixels in the decompressed image representation correlating to at least one lookup type pixel run represented in the encoded alpha channel data may be processed. The processing may include a determination of an alpha channel value based on pixel data, specific to a pixel correlated to the lookup type pixel run, in the encoded alpha channel data and an application of the alpha channel value to the pixel.
