Tilman Hausherr updated PDFBOX-2070:
------------------------------------
Description:
If there are several filters (filter array) in an image, PDFBox is inserting an
empty DecodeParms object here
{code}
params.setItem(COSName.DECODE_PARMS, getDecodeParams(params, index));
{code}
instead of either inserting an empty COSArray, or (better) do nothing. Saving
such a PDF results in it not being displayable in the Acrobat Reader.
Test code:
{code}
PDDocument d = PDDocument.load("before.pdf");
new PDFRenderer(d).renderImage(0);
d.save("after.pdf");
{code}
The rendering is important because without it, the filtered objects aren't
decoded.
