Summary: Setting accessibility in Java
Product: Fop
Version: 1.0
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: blocker
Priority: P2
Component: pdf
AssignedTo: [email protected]
ReportedBy: [email protected]
When setting accessibility with :
A. userAgent.setAccessibility(true)
and then generating PDF, an exception occurs :
-----
ERROR org.apache.fop.area.AreaTreeModel - Error while rendering page 1
java.lang.NullPointerException
at
org.apache.fop.render.pdf.PDFPainter.prepareImageMCID(PDFPainter.java:152)
-----
It seems that logicalStructureHandler of PDFPainter is null.
The cause is that the logicalStructureHandler is set when calling :
B. FopFactory.newFop(String outputFormat, FOUserAgent userAgent, OutputStream
stream)
which calls :
PDFDocumentHandler.startDocument()
where it tests accessibility of the attached FOUserAgent.
Issue is due to the fact that at the moment calling "B", we couldn't have
correctly set "A" so, the logicalStructureHandler of PDFPainter remains null.
A solution is to change method FopFactory.setAccessibility() to public, so that
we can set accessibility before calling "B".
