Hi,
I am trying to clip some text within an SVG block using FOP. Below I attach
a version of the FOP-XML I am using. When run with fop.sh that comes with
the FOP distribution (version 0.20.4), it works fine and clips as expected -
varying the clipPath's width will show more or less text accordingly.
However, when I pass the FOP-XML to my processor (a servlet) I get the
NullPointerException shown after the XML. It seems to be caused by the url
not being found but I am at a loss as how to tell the processor that I want
to refer to the document itself. Is there a configuration parameter that
needs to be set? Is there another way to pass in the reference to the
clipPath?
Note that I have tried replacing the clip-path attribute with both of the
following which, although they avoid the error, fail to clip the text.
clip-path:#xpointer(#4203)
clip-path:#xpointer(id(4203))
Any help would be greatly appreciated,
Michael
