public class JSVGComponent extends JGVTComponent
The rendering process can be broken down into five phases. Not all of those steps are required - depending on the method used to specify the SVG document to display, but basically the steps in the rendering process are:
If the loadSVGDocument(String)
method is used,
the SVG file is parsed and an SVG DOM Tree is built.
Once an SVGDocument is created (using the step 1 or if themethod has been used) - a GVT tree is constructed. The GVT tree is the data structure used internally to render an SVG document. see the
setSVGDocument(SVGDocument)
org.apache.batik.gvt
package.
If the document is dynamic, the scripts are initialized and the SVGLoad event is dispatched before the initial rendering.
Then the GVT tree is rendered. see the org.apache.batik.gvt.renderer
package.
If the document is dynamic, the update threads are started.
Those steps are performed in a separate thread. To be notified to what
happens and eventually perform some operations - such as resizing the window
to the size of the document or get the SVGDocument built via a URI, five
different listeners are provided (one per step):
,
SVGDocumentLoaderListener
,
GVTTreeBuilderListener
,
SVGLoadEventDispatcherListener
,
GVTTreeRendererListener
.UpdateManagerListener
Each listener has methods to be notified of the start of a phase, and methods to be notified of the end of a phase. A phase cannot start before the preceding has finished.
The following example shows how you can get the size of an SVG document. Note that due to how SVG is designed (units, percentages...), the size of an SVG document can be known only once the SVGDocument has been analyzed (ie. the GVT tree has been constructed).
final JSVGComponent svgComp = new JSVGComponent(); svgComp.loadSVGDocument("foo.svg"); svgComp.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() { public void gvtBuildCompleted(GVTTreeBuilderEvent evt) { Dimension2D size = svgComp.getSVGDocumentSize(); // ... } });
The second example shows how you can access to the DOM tree when a URI has been used to display an SVG document.
final JSVGComponent svgComp = new JSVGComponent(); svgComp.loadSVGDocument("foo.svg"); svgComp.addSVGDocumentLoaderListener(new SVGDocumentLoaderAdapter() { public void documentLoadingCompleted(SVGDocumentLoaderEvent evt) { SVGDocument svgDoc = svgComp.getSVGDocument(); //... } });
Conformed to the single thread rule of swing, the listeners are executed in the swing thread. The sequence of the method calls for a particular listener and the order of the listeners themselves are guaranteed.
The JSVGComponent
can pick up some informations to a user
agent. The
provides a way to control the
resolution used to display an SVG document (controling the pixel to
millimeter conversion factor), perform an operation in respond to a click on
an hyperlink, control the default language to use, or specify a user
stylesheet, or how to display errors when an error occured while
building/rendering a document (invalid XML file, missing attributes...).SVGUserAgent

An UpdateManager is only created for Dynamic documents. By
default the Canvas attempts to autodetect dynamic documents by
looking for script elements and/or event attributes in the
document, if it does not find these it assumes the document is
static. Callers of this method will almost certainly want to
call setDocumentState(ALWAYS_DYNAMIC) before loading the document
(with setURI, setDocument, setSVGDocument etc.) so that an
UpdateManager is always created (even for apparently static documents).public void resumeProcessing()
