> Hi, i'm trying to extract some pages and the renderer got some errors.
> The result has lots of lost information.
> WARNUNG: Changing font on <~> from <Hidden HorzOCl> to the default font
> Okt 15, 2014 6:50:48 PM org.apache.pdfbox.pdmodel.graphics.xobject.PDPixelMap getRGBImage
> SCHWERWIEGEND: Something went wrong ... the pixelmap doesn't contain any data.
> Okt 15, 2014 6:50:48 PM org.apache.pdfbox.util.operator.pagedrawer.Invoke process
> WARNUNG: getRGBImage returned NULL
> Okt 15, 2014 6:50:48 PM org.apache.pdfbox.pdmodel.graphics.xobject.PDPixelMap getRGBImage
> the first error is a missing font (well this should not result in information lost, i think there will be a font replacement)
> the next error is the importent one i think
> the pdf file is located here: http://kt.uni-due.de/sites/default/files/attachments/lecture_amc.pdf
> i've used the secend page (page:1 in pdfbox)
> the result should look like page2.png but i get error.png
> i'm using just some demo lines
> PDDocument.load(path.toFile());
> document.getDocumentCatalog().getAllPages().get(1);
> page.convertToImage(BufferedImage.TYPE_INT_ARGB, 300);
> ImageIO.write(page.getImage(), "png", Files.newOutputStream(Paths.get("imagetest.png")));
> other pdf files work. i know there is a version 2.X but there is no release?
