> We use PDFBox to render PDF's. Additionally, we have the posibility to add different kinds of annotation (stamp, marks, free text, notes..) like in a wysiwyg-editor. To do this, it is necessary that we paint these annotations on our own.
> Another reason is not to paint all parts: for example we have a pdf with an embedded picture. Behind the picture we have the OCR-text to this picture. This text is only needed for searching und should not be painted.
> Thus it would be useful to use our own derived PageDrawer. As I see there are some things to change.
> a.) remove the final from PagerDrawer-class.
> b.) make some global-variables (graphics, xform, pageSize...) protected,
> c.) also some methods like setRenderingHints should be protected
> d.) maybe the possibility to say to the PDFRender which PageDrawer should be used.
