read() template<typename T , long n = 2> VecRaster<T, n> Euclid::Fits::ImageRaster::read ( ) const Read the whole data unit as a new VecRaster. 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. Examples EleFitsTutorial.cpp.
