Well, you are not transforming the rectangle but merely the two corner points on one diagonal (rectXPt, rectYPt) and (tempEndXPt, tempEndYPt). In case you merely want to consider transformations like the one in your message, i.e. > 1.1342565 0 0 1.199793 0 0 cm only transforming those two points suffices because this transformation matrix only scales but neither rotates nor skews. Thus, you know the transformed rectangle will have edges parallel to the x and y axis respectively. If you want to consider generic transformations which may rotate or skew, though, you'll have to transform all four points (well, it actually suffices to transform three because the image of the rectangle will still be some parallelogram which allows you to calculate the fourth point using the other three points). > 2) Is there an easier way? It depends on your definition of "easier". If you are well acquainted with linear algebra, writing it using the iText Vector and Matrix classes might look more intuitive. The calculations behind the scenes are the same, though.
