PDF export with images and vector graphics

hi everyone!

we're trying to save some pdfs of the code below, but we're having some problems with the images on the background.

we can save normally the vector lines, but the background images don't get loaded and don't get saved on the pdf.

can anyone help saying what's the problem, or suggest another way to load/save the images?

ps.: we cannot save a tiff, we need the lines to be vector (no problem about the background images being bitmaps)

another help: can anyone suggest how to save the pdfs with sequential names? (like foto1.pdf, foto2.pdf...) because we'll need to generate a lot of pdfs, and we can't overwrite them

the error we get is:

Exception in thread "Animation Thread" java.lang.RuntimeException: No set() for PGraphicsPDF
