Summary: allow "opacity" attribute on group of paths
Product: Batik
Version: 1.7
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: SVG DOM
AssignedTo: [email protected]
ReportedBy: [email protected]
I have a bit of code that uses batik at a low level, and sending SVG with the
following elements seems to result in the GraphicsNode not painting anything.
<g opacity="0.1">
<path
d="M101.5,325.5c0-37.396,19.75-70.263,49.364-88.731h-5.481C117.096,256.154,98.5,288.693,98.5,325.5
c0,36.062,17.85,68.032,45.178,87.543h5.324C120.425,394.373,101.5,362.107,101.5,325.5z"/>
<path
d="M310.5,325.5c0,36.607-18.925,68.873-47.501,87.543h5.324c27.327-19.511,45.177-51.48,45.177-87.543
c0-36.807-18.596-69.346-46.883-88.731h-5.481C290.75,255.237,310.5,288.104,310.5,325.5z"/>
</g>
changing "opacity" to "fill-opacity" results in the desired behavior when
painting. But according to the SVG spec, opacity should be allowed on groups?
Here's now the GraphicsNode is created.
// Parse the SVG document.
SVGDocument doc = new
SAXSVGDocumentFactory(XMLResourceDescriptor.getXMLParserClassName()).createSVGDocument(null,
data.inputStream());
UserAgent userAgent = new UserAgentAdapter();
BridgeContext ctx = new BridgeContext(userAgent, new
DocumentLoader(userAgent));
ctx.setDynamicState(BridgeContext.STATIC);
GraphicsNode node = new GVTBuilder().build(ctx, doc);
Sorry this isn't more detailed - let me know if this isn't enough information.
