Tilman Hausherr commented on PDFBOX-1969:
-----------------------------------------
I first isolated the "JPEG only" stuff to deal with shorter code.
I then applied a similar change than I did in CCITT. The test now works. An
image-to-pdf test I did (temporarly modified the example to use that method)
also worked. What I couldn't test is whether the alpha thing works, i.e.
whether it is possible to put a semi transparent jpeg in a PDF.
This was done in rev 1577734 and rev 1577735. John, please review this, if you
want.
