[jira] [Updated] (PDFBOX-2692) Possibilty to use an own PageDrawer
and/or overwrite the PageDrawer
[ https://issues.apache.org/jira/browse/PDFBOX-2692?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tilman Hausherr updated PDFBOX-2692:
------------------------------------
Description:
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.

We use the PDFBox to render PDF's. As addition we has also has the posibility to add different kinds of annotation (stamp, marks, free text, notes..) like in an wysiwyg-editor To do this it is necessary that we paint this annotations at our own.
Another reason is not to paint all parts, as example we have an pdf with an embedded picture. Behind the picture we have the ocr-text to this picture. This text is only necessary for searching und should not be painted.
And so it will be fine that we can use an own derivated 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.
