Subject [jira] [Commented] (PDFBOX-1067) PDF Scan from Xerox WorkCentre 5030 renders as all black
Date Tue, 13 Nov 2012 22:50:12 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-1067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13496637#comment-13496637

Dave Smith commented on PDFBOX-1067:
------------------------------------

My harness is like this ...

      ImageIO.scanForPlugins();
		PDDocument document = PDDocument.load(new File("ItDoesntWorkScan.pdf"));
		List<PDPage> pages = document.getDocumentCatalog().getAllPages();
		int pageCnt=1;
		for (PDPage page : pages)
	{
		
			BufferedImage pageImage = page.convertToImage(BufferedImage.TYPE_BYTE_GRAY, 200);
			FileOutputStream out = new FileOutputStream("page."+pageCnt+".png");
			ImageIO.write(pageImage, "png", out);
			out.close();
			pageCnt++;
	}
		document.close();
	

Works perfectly. Are you doing something different?

>             Project: PDFBox
>          Issue Type: New Feature
>          Components: PDModel
>    Affects Versions: 1.6.0
>         Environment: Tested on MacOS X 10.6.7, Ubuntu 10.10, Windows 7
>            Reporter: Sarah Kelley
>              Labels: JBIG2

>     The file "ItDoesntWorkScan.pdf" renders to an empty
>     black page. This file is a copy of "ItDoesntWorkPrinted.pdf"
>     that has been printed on paper, and then scanned with
>     a Xerox WorkCentre 5030 scanner, which then emails a pdf file
>     back to the user.
>     Tested On:
>         - Mac OS 10.6
>         - Windows 7
>         - Ubuntu 10.10
>     Unfortunately, the WorkCentre 5030 doesn't appear to have
>     many user-settable options for scanning to PDF, so we weren't
>     really able to try scanning with settings other than the defaults.
> Will attach pdf and code to demonstrate.
