BuildRasterPyramidsOperation class final
An operation that builds pyramids for a raster.
A BuildRasterPyramidsOperation is returned by RasterPyramids.buildPyramids. While the build is in progress, the same operation is also available from RasterPyramids.activeBuildOperation. Use this object to observe progress, request cancellation, and await the pyramid information produced by the build.
When the operation completes successfully, BuildRasterPyramidsOperation.getResult returns information about the pyramid set that was built, and RasterPyramids.pyramidInfo is refreshed with that same information.
