Note that this function does NOT eliminate the need for reverse-thinking when designing PDFs. Origin 0, 0 is the lower left corner. This function only MOVES this origin (0,0) - it does not reverse the Y-axis as some people might belive and want (including myself).

Not only this function is useful if you are tired of using the lowerleft side of the page, but it is also great if you need to rotate your page.. I have a project in which I need to rotate the page 180 due to calibration problems.. With this function I could reset the origin and the rest of the PDF worked just fine.. I also think that this function primarly has been mode for situations like these... This function can also be used as a calibration feature, though I dont do it myself, I can think that it will work very nice if your whole document is out of calibration for lets say 1 mm..

This function is useful if you're tired of trying to deal with an axis that has a point of origin in the lower left-hand corner of the page. Enjoy.
