             Summary: Weired spots in rendering result ofscanned 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


The rendering of some scanned Documents in PDF 1.6 rormat result shows weired 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 Magick is absolute perfect. Besides the mentioned spots, there are some other
rendering bugs resulting of wrong positioning of the graphical elements of the PDF.
