I have a PostScript object having a known bbox. I want to insert this object into the current image where I known the bbox which this inserted object should have in the current user space. How can I calculate, in PostScript code, the transformation matrix which should be concatenated to the CTM in order to get the expected result ? Note that translation, scaling and rotation may be necessary.
