Hi gang,
this is driving me nuts ;o( Once you have passed a SVG document to the ImageTranscoder, modifying the 'visibility'-attributes has no impact anymore on the transcoder output. It only has impact on the output when you modify the attributes before passing the document object the first time.
I know there are some points to remember when using JSVGCanvas [ see http://koala.ilog.fr/batik/mlists/batik-users/archives/msg03051.html ], however I can't seem to find the reason for this odd behaviour when using the ImageTranscoder.
Here is a modified DOMRasterizer-Example taken from Batik's website to illustrate the problem (see source comments for more information)
Any ideas or workarounds ?
The problem is that the Transcoder was not cleaning out the ViewCSS it associated with the Document, and since it wasn't constructed in a dynamic context the ViewCSS wasn't updated as the DOM changed (visibility is a CSS property so the value comes from the ViewCSS). Fortunately the fix is very simple, add the following at: xml-batik/sources/org/apache/batik/transcoder/SVGAbstractTranscoder.java:299
this.root = gvtRoot; + ctx.dispose }
This should be the last line of:
protected void transcode(Document document,
String uri,
TranscoderOutput output)I'll commit this to CVS later tonight.
