Remarks
geoDataset |
an input Raster, RasterDataset, RasterBand, or RasterDescriptor The geoDataset identifies the cell values which will be selected inside or outside of a specified circle. |
Circle |
an ICircularArc defining circle for the selection criteria The coordinates are specified in map units and are in the same units as the geoDataset. |
selectInside |
a Boolean identifying which cells should be selected, those contained in or external to the input circle If True, the cells inside the input CircleArc should be selected and written to the output Raster. All cells outside the circle will receive NoData on the output Raster. If the Boolean is False, the cells outside the input circle should be selected and written to the output Raster. All cells inside the circle will receive NoData on the output Raster. |
- The method returns a reference to a Raster object.
