Abstract
One or more techniques and/or systems are disclosed for converting an unsupported continuous tone image file with an opacity layer to an application supported image. An opacity mask is created from an extracted alpha channel portion of the unsupported image file, where the alpha channel comprises transparency (opacity) information for the image. The unsupported image file can comprise an eight-bit alpha channel that indicates transparency for one or more portions of the image. The remaining channels of the unsupported image, after the alpha channel is extracted, can be used to create an image, which is combined with the opacity mask, to generate a supported image with a transparency layer.
