Examples with BoundingBox org.opennms.features.topology.api.BoundingBox used on opensource projects

Example 11 with BoundingBox

use of org.opennms.features.topology.api.BoundingBox in project opennms by OpenNMS.

the class DefaultMapViewManager method setBoundingBox.

@Override
public void setBoundingBox(BoundingBox boundingBox) {
    BoundingBox oldBoundingBox = getCurrentBoundingBox();
    BoundingBox bbPrime = boundingBox.computeWithAspectRatio(getViewPortAspectRatio());
    BoundingBox mPrime = m_mapBounds.computeWithAspectRatio(getViewPortAspectRatio());
    double oldScale = m_scale;
    m_scale = Math.log(bbPrime.getWidth() / (double) mPrime.getWidth()) / Math.log((m_viewPortWidth / 2.0) / (double) mPrime.getWidth());
    m_scale = Math.min(1.0, m_scale);
    m_scale = Math.max(0.0, m_scale);
    m_scale = ((double) Math.round(m_scale * 10.0)) / 10.0;
    Point oldCenter = m_center;
    m_center = boundingBox.getCenter();
    BoundingBox newBoundingBox = getCurrentBoundingBox();
    // TODO: Sonar is warning on the equals comparison of m_scale and oldScale
    if (!oldCenter.equals(m_center) || oldScale != m_scale || !oldBoundingBox.equals(newBoundingBox)) {
        fireUpdate();
    }
}

Example 12 with BoundingBox

use of org.opennms.features.topology.api.BoundingBox in project opennms by OpenNMS.
