PostCompose

The PostCompose method modifies this transform's matrix by postmultiplying it with the specified transform's matrix.

ODTransform PostCompose (in ODTransform transform);

transform

A reference to the transform whose matrix is to be postmultiplied with this transform's matrix.

return value

A reference to this transform after the postcompose operation.

DISCUSSION

Postcomposing multiplies this transform's matrix on the right side by the specified transform:

   this Æ this  transform

The resulting transform has the same effect as applying the two original transforms in sequence: first this transform, then the other.

OVERRIDING

If you subclass ODTransform to create a nonlinear transform class, you must override this method. Your override method can call its inherited method at any point in your implementation (it does not matter where).
