| # Class STLayerRaster Extends STLayer Represents a single raster or a tiled raster. TheRaster contains a raster object that always contains the info on the entire raster and may contain the actual raster data (if IsAllocated()==true) General usage: - If the pyramid exists, use it (this means UsePyramid=true and the raster is large) - Else if the raster exists, use it - Else use the Raster Reader Painting calling sequence: - Layer is called by parent (scene) to paint. - Layer calls each painter (or a default) to PaintLayer() - Painter either pulls tiles from the layer (3d view) or calls back into layer through Paint(TheView,ThePainter) - Paint(TheView,ThePainter) calls Painter's PaintRaster() function for each tile in the pyramid or the whole raster Copyright, SchoonerTurtles LLP, 2009 @author Jim Graham #### Object Functions ##### Inherited From: STLayer
