X-Git-Tag: fop-1_0~380 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=d62f5f811c40bc3f0b20f0ae8d75cfb240be9c67;p=xmlgraphics-fop.git Added support for SVG 1.2 inside fo:instream-foreign-object. The code just used the basic SVGDOMImplementation for SVG 1.1. Now it delegates the DOM building to Batik code instead of to a normal DOM builder. git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@719616 13f79535-47bb-0310-9956-ffa450edef68 --- diff --git a/src/java/org/apache/fop/fo/XMLObj.java b/src/java/org/apache/fop/fo/XMLObj.java index 3330f41a5..e1eb47b46 100644 --- a/src/java/org/apache/fop/fo/XMLObj.java +++ b/src/java/org/apache/fop/fo/XMLObj.java @@ -217,6 +217,7 @@ public abstract class XMLObj extends FONode implements ObjectBuiltListener { /** {@inheritDoc} */ public void notifyObjectBuilt(Object obj) { this.doc = (Document)obj; + this.element = this.doc.getDocumentElement(); } } diff --git a/src/java/org/apache/fop/fo/extensions/svg/SVGDOMContentHandlerFactory.java b/src/java/org/apache/fop/fo/extensions/svg/SVGDOMContentHandlerFactory.java new file mode 100644 index 000000000..c5064da3f --- /dev/null +++ b/src/java/org/apache/fop/fo/extensions/svg/SVGDOMContentHandlerFactory.java @@ -0,0 +1,82 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
