RasterPyramidInfo class final
Information about a raster pyramid set.
A raster pyramid set is a collection of reduced-resolution copies of a raster. These reduced-resolution levels let the runtime display the raster more efficiently at smaller scales by using data that is already closer to the requested resolution.
Pyramids for a raster can be embedded within the raster file or in a separate pyramid file (.ovr). When returned from RasterPyramids.pyramidInfo, it describes the pyramid set available for the raster.
Pyramids stored in a separate pyramid file (.ovr) can be deleted using RasterPyramids.deletePyramids. After the pyramids are deleted, new pyramids can be built using RasterPyramids.buildPyramids.
