[jira] [Resolved] (PDFBOX-2692) Possibility to use our own and/or
overwrite PageDrawer class
[ https://issues.apache.org/jira/browse/PDFBOX-2692?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Hewson resolved PDFBOX-2692.
---------------------------------
Resolution: Won't Fix
Ok - so the conclusion here is that modified renderings of PDFs can be achieved by modifying the underlying PDF prior to rendering, using the PD API. For the common case of not wanting annotations rendered, we could add an option to the PageDrawer constructor - but we should follow up on that in a later issue.

> Issue Type: Wish
> Components: Rendering
> Affects Versions: 2.0.0
> Environment: JDK 1.8, Windows 7, PDF-Box - current trunk
> Reporter: Manfred Pock

> 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.
