Detailed Description

Unique type declaration for which dimensions are used in the input workspace.

Unique type declaration for the offset of coordinates Unique type declaration for the step size in transformation A restricted version of CoordTransform which transforms from one set of dimensions to another, allowing:

An offset
A reduction in the number of dimensions
A scaling

While a normal Affine matrix would handle this case, this special case is used in order to reduce the number of calculation.
