	PyramidPresent	Indicates if pyramids are present for the layer.
	Raster	Layer's Raster object.
	Renderer	Layer's renderer.
	RowCount	Number of rows in the layer.
	ShowResolution	Indicates if the raster resolution should be displayed in the Table of Contents.

Classes that implement IRasterLayer

Classes	Description
ImageServerLayer	Image server layer source and display options.
RasterLayer	Raster layer source and display options.
WCSLayer	WCS layer source and display options.

Remarks

The RasterLayer must be initialized with data before it can be used. When the layer is initialized, a default renderer is selected for the dataset based on the number of bands, statistics, and whether a colormap or other table exists for the data. Other internal properties of the layer are also set at this time.
