Abstract

An image processor includes a memory that stores image layers, α-layers associated with the image layers, and pointers linking image areas of the image layers with the α-layer. A method for blending multiple image layers includes obtaining a transparency value for an image area by reading a pointer associated with the image area and blending the image layers using the obtained transparency value.
