John Hewson commented on PDFBOX-1863:
-------------------------------------
It seems that PDFPagePanel was not created with serious use in mind. Feel free
to checkout the source from svn and make whatever changes are needed and attach
an _svn diff_ to this issue.
> Can't resize PDFPagePanel render
> --------------------------------
>
> Key: PDFBOX-1863
> URL: https://issues.apache.org/jira/browse/PDFBOX-1863
> Project: PDFBox
> Issue Type: Bug
> Reporter: Álison Fernandes
>
> 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).
