Example 4 with UserAgentAdapter

use of org.apache.batik.bridge.UserAgentAdapter in project scout.rt by eclipse.

the class SVGUtility method readSVGDocumentForGraphicalModification.

/**
 * Parses a SVG document read by the given input stream and attaches a GVT tree. An attached GVT tree is required for
 * performing CSS, text size and and bounding box operations on the SVG document.
 * <p/>
 * The resulting bridge context holds a reference to the SVG document {@link BridgeContext#getDocument()}
 * <p/>
 * <h1>Important:</h1> Callers are required to invoke {@link BridgeContext#dispose()} on the returned bridge context
 * as soon as the bridge or the document it references is not required anymore.
 * <p/>
 * If the documents needs not be manipulated, use {@link #readSVGDocument(InputStream)} instead.
 *
 * @param in
 *          input stream the SVG document is read from.
 * @return Returns a bridge context that holds references to the SVG document as well as to the GVT tree wrapping
 *         objects.
