After exporting PDFs from Goodnotes 5 to iOS, I realized that images embedded in jpeg2000 / jp2 format were exported to the PDF file.
Is there a PDF viewer that can be used to view such PDFs with JP2 images? I've tried the default document viewer, okular and the Foxit player. The document viewer and okular display a very pixelated image, while the Foxit player displays nothing at all.
Any help would be appreciated.
