writeRegion() void writeRegion ( FileMemRegions< N >  regions, const TRaster &  raster  ) const Write a Raster at a given position of the data unit. Parameters regions The in-file and in-memory regions raster The raster to be written In-file and in-memory (raster) regions are specified as the first parameter. Max bounds (-1) can be used in one, several, or all axes. Shortcuts offered by FileMemRegions and Region can be used to implement special cases: // Write the whole raster at position (10, 20, 30) du.writeRegion<3>({10, 20, 30}, raster); // Write the whole HDU with a region of the raster starting at (10, 20, 30) du.writeRegion<3>({Region<3>::whole(), {10, 20, 30}}, raster); Note that the raster dimension can be lower than the HDU dimension. For example, it is possible to write a 2D raster in a 3D HDU. // Write the 3rd plane of raster into the 5th plane of the HDU du.writeRegion<3>({{0, 0, 4}}, raster.section(2));
