Text on Path - startOffset range
Hello Everyone,
I am creating a wheel with labels on it (text on the path) but as text
outside the path is clipped, I must to render these cases twice (the second
time out of 0-100% range), see the attached test case. But it seems to be
not supported by Batik as Squiggle tools returns the following exception:
org.apache.batik.bridge.BridgeException: file:/D:/data.svg:24
The attribute "startOffset" of the element <textPath> is invalid

Only Firefox 4.0beta or Opera renders it as expected. Is there any chance to
support this also in Batik? I have no idea what workaround to choose for
this...

Jan

Unfortunately I don’t have time right now to look into the correctness
of this example to verify if it’s a bug. I would suggest as a simple
workaround to define a second path that is just the top half arc of the
circle, and centre a single “December” string on it. This seems better
than splitting the string across the endpoints of the circle path
anyway.

It's me again. I've prepared more complex example and these startOffset ranges turned out to be still problematic (particularly with the text-anchor attribute set to the middle), see the attached example (December ember).
The text anchor is shifted so that text is not centered at the specified point so both occurrences appear in different positions (they should match).
Should I report it somewhere?

Jan

Wow, what amazing speed of implementing this!
I've already built it from sources and it works like a charm.
Thanks a lot!

I think you are right. I can’t find anything in the SVG spec that
disallows negative percentages. This is fixed in SVN now (r1073181).
