readTo() [2/2] void readTo ( Subraster< T, N, TContainer > &  subraster ) const Read the whole data unit into an existing Subraster. Deprecated: There are several options to read the whole data unit: as a new VecRaster object; by filling an existing Raster object; by filling an existing Subraster object. In the last two cases, the raster or subraster is assumed to already have a conforming shape. Warning Filling a Subraster is much slower than filling a Raster.
