Subject Re: [jira] Commented: (PDFBOX-688) Refactoring rendering-related classes/methods for extensibility
Date Fri, 09 Apr 2010 18:44:06 GMT
Hi Daniel,

as I'm currently looking at implementing support for some more text rendering modes in PageDrawer
(PDFBOX-678) I would like to understand if that might affect the .NET Version. Although I
don't have a completed version this is a list of the potential operations I will be using.


* generating a Shape based on TextLayout.getOutline()
* filling, drawing and clipping using that Shape
* possibly AlphaComposite
* possibly GlyphVector 

Are there things I should avoid?

Kind regards


Maruan Sahyoun
