This solution requures extra native libraries but that's Ok for me. > Weird spots in rendering result of scanned PDF 1.6 document > ----------------------------------------------------------- > > Key: PDFBOX-4320 > URL: https://issues.apache.org/jira/browse/PDFBOX-4320 > Project: PDFBox > Issue Type: Bug > Components: Rendering > Affects Versions: 2.0.11 > Reporter: Christian Lauer > Priority: Major > Labels: JPEG2000, JPG2000, JPXDecode, JPXFilter > Attachments: PDFBOX-4320.jp2, scanned.pdf, weired.tiff > > > The rendering of some scanned Documents in PDF 1.6 format result shows we= ired blurred black spots. It seems to me that the scanning software detects= form areas and moves them in separate elements, which are not rendered by = PDFBox. The result in Adobe Reader and other conversion tools like Image Ma= gick (which is using ghostscript as PDF renderer) is absolute perfect. Besi= des the mentioned spots, there are some other rendering bugs resulting of w= rong positioning of the graphical=C2=A0elements of the PDF. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@pdfbox.apache.org For additional commands, e-mail: dev-help@pdfbox.apache.org
