- ApplyMatrix[ <Matrix>, <Geometric Object>]
- Transforms the object O so that point P of O is mapped to
- point M*P (with matrix M) 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>, <Image>]
- Applies the same transformation as above to an image.
