CoClasses that implement IRasterCursor
| CoClasses and Classes | Description |
|---|---|
| RasterCursor (esriDataSourcesRaster) | A raster cursor class. |
Remarks
The IRasterCursor interface controls enumeration through the PixelBlocks in a Raster. It is useful for rasters that are too large to be brought into memory at once.
The RasterCursor divides the Raster into blocks 128 pixels high that span the full width of the raster. Each successive PixelBlock is read 128 lines below the previous PixelBlock.
To create a RasterCursor, use the IRaster::CreateCursor or IRaster2::CreateCursorEx method.
