Remarks
The following transformation is represented by this matrix:
C#
Copy
            |sx, ry, 0|
|x, y, 1| * |rx, sy, 0| = |x', y', 1|
            |dx, dy, 1|
where (x,y) are the world coordinates, and (x', y') are the page coordinates.

An alternative interpretation of this matrix is a rhombus, where the absolute coordinate of its origin is given by (dx, dy), and which is spanned by the two basis vectors (sx,ry) and (rx, sy). By inverse transformation of a given point one gets the coordinates inside this rhombus in terms of the spanning vectors.
