View in QML C++ View on GitHub Sample viewer app
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. Press Take screenshot
, and a screenshot image will display over the map. Note that there may be a small delay if the map is still rendering when you push the button.
How it works
The exportImage
function is executed on the MapView
.
Once the asynchronous task completes, a QML Image uses the image URL to render an Image on the screen.
Relevant API
capture, export, image, print, screen capture, screenshot, share, shot
