An application can create a soft-mask image from the information to be used as a source of mask shape or mask opacity in the transparency imaging model. 2 The image’s data stream includes color channels that have been preblended with a background; the image data also includes an opacity channel. An application can create a soft-mask image with a Matte entry from the opacity channel information to be used as a source of mask shape or mask opacity in the transparency model.
