An overlay that contains a frame with an image to display in the view. More...
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 real-time 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.
Because 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. The overlay can contain exactly one image at any given time, however, multiple overlays can be added and rendered at the same time on the SceneView.
This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
[read-only] extent : Envelope
opacity : real
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.
visible : bool
The visibility of the ImageOverlay.
