- ApplyMatrix[ <Matrix M>, <Geometric Object O>]
- Transforms the object so that point P of O is mapped to
- point M*P in case M is a 2x2 matrix or
- point project(M*(x(P), y(P), 1)) where project is a projection mapping point (x,y,z) to (x/z, y/z) in case of 3x3 matrix.
- ApplyMatrix[ <Matrix M>, <Image I>]
- Applies the same transformation as above to image I.
