We can further manipulate images through the use of pdf_rotate() and pdf_skew()—two functions whose purposes you should be able to guess quite easily. Both take a PDF document reference as their first parameter. The pdf_rotate() function then takes one extra parameter—how much to rotate the coordinate system, in degrees—whereas pdf_skew() takes two extra parameters: how much to skew the coordinate system in the X direction and how much in the Y direction.
Try adding these two lines just after the call to pdf_begin_page() inside the loop of the previous script:
pdf_skew($pdf, 10, 10);
pdf_rotate($pdf, 5);
