The only function of the Axes instance variable is to specify a context for the other filter instance variables. The affect of this variable is local to this region, and does not change the behavior of any filter that operates on this region. 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.
