well, what has to be transparent? Background images or overlaying text?

The XREF is built incrementally in parallel to file writing. So your PDF
object has to wait, until it is it's turn to output to the file.

Example: image xObject on page in PDFRenderer

- create xObject: say PDF object ID 27
- add xObject to page objects
- output page objects: method "toPDF" of objects say 20-30 is invoked
        . object 27: do the data/processing intensive things at this time

If you send me the code, I can figure out what the problem is.
