double GDALGeneric3x3RasterBand::GetNoDataValue | ( | int * | pbSuccess | ) | [virtual] |
Fetch the no data value for this band.
If there is no out of data value, an out of range value will generally be returned. The no data value for a band is generally a special marker value used to mark pixels that are not valid data. Such pixels should generally not be displayed, nor contribute to analysis operations.
This method is the same as the C function GDALGetRasterNoDataValue().
pbSuccess | pointer to a boolean to use to indicate if a value is actually associated with this layer. May be NULL (default). |
