Fixed with JAI and a new Version of pdfbox
using Version 2.0
printable = renderer.renderImageWithDPI(pageNum, 300,
ImageType.RGB);
ARGB -> results in non readable

> 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

> the result should look like page2.png but i get error.png

> 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?
