| IRasterCursor (esriGeoDatabase) | Provides access to members that provide optimized raster access. |
Remarks
TheRasterCursor object is used for iterating through all of the pixel blocks in a raster. It is useful for rasters that are too large to be brought into memory at once.
IRaster::CreateCursor or IRaster2::CreateCursorEx can be used to create a RasterCursor .
The IRaster::CreateCursor divides the Raster into blocks of 128 pixels high (rows) that span the full width of the raster. Each successive pixel block is read 128 lines below the previous pixel block. IRaster2::CreateCursorEx divides the Raster with your specified block size.
