> I tried to use PDFPagePanel to render a PDF to an applet but, I had to change my implementation because PDFPagePanel wasn't resizing the rendering so it could be bigger. 
> I've checked in the source code (of pdfbox-1.8.2 and in the SVN trunk), the Dimension drawDimension var that sets the rendering size isn't accessible from outside and it will draw using the dimension of the PDF Cropbox.
> My current implementation to bypass this is:
> - Create a JPanel
> - Render the page to an image using PDPage.convertToImage(...)
> - Add the image to the JPanel using JLabel picLabel = new JLabel(new ImageIcon(page.convertToImage(...)));
> - Repeat for all the pages
> - Set the panel as a viewport in a JScrollPane
> Unfortunately, this method takes way too much time if you have to render things multiple times (~1 second for more complex pages with forms).
