Detailed Description

Prerequisite

• GLPCDisplayListEntry

Synopsis

GLPCTexturedImage is used to convert an image to texture objects for display. The pixels array contains pixels stored as RGB triples. This class is typically only used by GLPixelCanvas If the image is larger than the maximum texture size, it will be broken into pieces that fit.
