Take a screenshot of the map.
Use case
GIS users may want to export a screenshot of a map to enable sharing as an image or printing.
How to use the sample
Pan and zoom to find an interesting location, then use the button to take a screenshot. The screenshot will be displayed. Note that there may be a small delay if the map is still rendering when you push the button.
How it works
- Wait for the MapView to finish rendering the Map.
- Call
mapView.ExportImageAsync()to get theRuntimeImage, which is a bitmap image. - Use the
RuntimeImage.ToImageSourceAsyncextension method to get a copy of the image that is compatible with native image display controls.
