Example 1 with SVGMatrix

use of org.opennms.features.topology.app.internal.gwt.client.svg.SVGMatrix in project opennms by OpenNMS.

the class TopologyViewImpl method calculateNewTransform.

@Override
public SVGMatrix calculateNewTransform(GWTBoundingBox bounds) {
    int iconMargin = 50;
    int iconLeftMargin = iconMargin + 50;
    int topMargin = iconMargin + 50;
    SVGElement svg = getSVGElement().cast();
    final int svgWidth = getPhysicalWidth();
    final int svgHeight = getPhysicalHeight();
    double scale = Math.min(svgWidth / ((double) bounds.getWidth() + iconLeftMargin), svgHeight / ((double) bounds.getHeight() + topMargin));
    scale = scale > 2 ? 2 : scale;
    double translateX = -bounds.getX();
    double translateY = -bounds.getY();
    double calcY = (svgHeight - (bounds.getHeight() * scale)) / 2;
    double calcX = (svgWidth - ((bounds.getWidth()) * scale)) / 2 + getLeftMargin();
    SVGMatrix transform = svg.createSVGMatrix().translate(calcX, calcY).scale(scale).translate(translateX, translateY);
    return transform;
}
