Re: DOCBOOK-APPS: FOP and SVG?

[Stefan Bylund <steby at enea dot se>]

Hi,

The problem was the SVG image itself, not the DocBook document. The SVG image
validates correctly against the SVG DTD and it can be viewed in the Batik SVG
browser. However, FOP can not handle it properly when generating a PDF. The
problem seems to be the <polygon> tag. If I replace the <polygon> with a simpler
<rect> tag, FOP can handle the image properly. It seems that FOP has problems with
the <polygon> tag or does not yet support it...

Regards,
Stefan Bylund
