We have some PDFs that were created with JPEG2000 images in them (*.jp2 files). Using PDFKit, and also WebKit, the images in these PDFs in some cases don't display at all, and in others cases appear badly warped. You can view the PDF using either Adobe Reader, or the Chrome app, and the images appear fine, so it's clearly not an issue of a corrupt PDF. Also, 3rd-party commercial iOS controls like PSPDF and FoxIt display the images fine, so it's clearly an issue with PDFKit and WebKit. Any known workarounds?

Never got an answer to this, unfortunately, even after posting it as a bug to Apple. For the time being, we told the customer that they have re-generate the PDFs with the JPEG2000s as new PDFs without them. They don't want to buy the 3rd-party library so this is the only solution at this point.
