The 2d and 1d functions do not modify extent of the higher dimensions. Increments do not include size of data type, so should be used after pointers have been casted to their actual type. Returns a pointer for reading the scalar point data. Coordinates are relative to image origin. Extent mins are used for unspecified coordinates.
Coordinates are relative to image origin.
Extent mins are used for unspecified coordinates. Different methods for setting the WholeExtent. The 2d and 1d functions do not modify WholeExtent of the higher dimensions. The image extent is the largest region that can be requested from the pipeline. Different methods for getting the WholeExtent.
