PdfBox write Page to Image scales Signatures

when trying to create an Image from a signed PDF Page, the resulting image shows the signatures but the signatures are not displayed correctly. For example, the original contains two signatures next to each other in the bottom section. In the resulting image the signatures look like they have been scaled up and are overlapping. Furthermore, there's a signature in the top right corner. This signature looks scaled up in the resulting image and is cut off to the right. What is happening here? What am I doing wrong? I'm pretty new to working with PDFs on this level.

Hope that makes sense. Please see below for the differences (I've cut out other content).

Here's the code I'm using:

List<PDPage> pages = inputDocument.getDocumentCatalog().getAllPages();
PDPage page = pages.get(0);
BufferedImage image = page.convertToImage(BufferedImage.TYPE_INT_RGB, PDF_RESOLUTION);
String fileName = "converted_image_" + (i + 1);
ImageIOUtil.writeImage(image, "png", fileName, BufferedImage.TYPE_INT_RGB, PDF_RESOLUTION);

here's the original original

and now the distorted version distorted

As suggested by Tilman Hausherr, I was using the current 1.8.x stable release which has problems with annotations appearances. This led to the seen behaviour. Testing with the current 2.0 SNAPSHOT solves this problem.

Now we are eagerly awaiting the release of 2.x :)

From what I've seen, they totally reworked how creating images from a PDF(Page) should be done so I'm not sure about the probability of a backport.

Hope that helps for anyone else coming across this.
