Class ImageOverlay

  • public final class ImageOverlay
extends Object
    An overlay that contains a frame with an image to display in the view.

    Currently, this feature is supported in a SceneView (3D) only. The overlay can contain exactly one image at any given time. Multiple overlays, however, can be added and rendered at the same time on the SceneView. An ImageOverlay can be used to quickly render frequently changing images. For example, rendering realtime sensor data, such as weather, where each static image represents a single frame from the radar. In this workflow, images are constantly updated via a new ImageFrame each time new data is available. This provides a fast-refreshing workflow where the underlying images are frequently updated as new data comes in.

    Since ImageOverlay does not support the rich processing and rendering capabilities of a RasterLayer , you should use Raster and RasterLayer for workflows that require static image rendering, analysis, and persistence.

    Image overlays are rendered above all other layers in the scene, draped on the surface, and below any graphics overlays in the scene view.

      • getExtent

        public Envelope getExtent()
        Gets the extent of the ImageOverlay.

      • isVisible

        public boolean isVisible()
        Gets the visibility of the ImageOverlay.
        Returns:
        the visibility of the ImageOverlay
        Since:
        100.8.0

      • setVisible

        public void setVisible​(boolean isVisible)
        Sets the visibility of the ImageOverlay.
        Parameters:
        isVisible - true if image should be visible
        Since:
        100.8.0

      • getOpacity

        public float getOpacity()
        Gets the opacity of the ImageOverlay.

        Opacity values range from 0.0 to 1.0, where 0.0 is fully transparent and 1.0 is fully opaque.

        Returns:
        the opacity for the ImageOverlay

        100.8.0

      • setOpacity

        public void setOpacity​(float opacity)
        Sets the opacity of the ImageOverlay.

        Opacity values range from 0.0 to 1.0, where 0.0 is fully transparent and 1.0 is fully opaque.

        Parameters:
        opacity - the opacity for the ImageOverlay
