示例1: OnClick
protected override async void OnClick()
{
activeMapView = ProSDKSampleModule.ActiveMapView;
Camera camera = await activeMapView.GetCameraAsync() ;
bool is2D = false ;
try {
is2D = activeMapView.ViewMode == ViewMode.Map;
}
catch(System.ApplicationException) {
return ;
}
if (is2D)
{
// in 2D we are changing the scale
double scaleStep = camera.Scale / _zoomSteps;
camera.Scale = camera.Scale + scaleStep;
}
else
{
// in 3D we are changing the Z-value and the pitch (for drama)
double heightZStep = camera.Z / _zoomSteps;
double pitchStep = 90.0 / _zoomSteps;
camera.Pitch = camera.Pitch + pitchStep;
camera.Z = camera.Z + heightZStep;
}
// the heading changes the same in 2D and 3D
camera.Heading = HollywoodZoomUtils.StepHeading(camera.Heading, -30);
// assign the changed camera back to the view
activeMapView.ZoomToAsync(camera);
