---------------------------------------
Summary: Filter.decode() modifies PDF if there is a filter array
Key: PDFBOX-2070
URL: https://issues.apache.org/jira/browse/PDFBOX-2070
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Tilman Hausherr
Attachments: after.pdf, before.pdf
If there are several filters (filter array) in an image, PDFBox is inserting an
empty DecodeParms object, instead of either inserting an empty COSAarray, 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.
