Camera

Take photos from a mobile device's camera and receive the byte data

• Triggers the built-in camera in iOS and Android, or the Photo Library picker in the iOS Simulator.

• Returns the captured photo to Haxe as JPEG byte data via a CameraEvent on the stage.

• Simulates a camera event from provided BitmapData for non-mobile platforms.

• Allows placing a BitmapData overlay over the built-in camera display.

  • TODO: Implement overlay in Android.

        #if !mobile
        // When testing on flash/desktop, CapturePhoto() should send this image...
        Camera.SetFakePhotoResult(Assets.getBitmapData("assets/mySimulatedPhoto.jpg"));
        #end

        // Show this PNG over the top of the native camera view
        Camera.SetCameraOverlayImage(Assets.getBitmapData("assets/img/camera-overlay.png"));
        
        // Take photo, limit max possible size to 1024x1024, JPEG quality 0.9
        Camera.CapturePhoto(1024, 0.9);

        ...
    }

    public function HandlePhotoCaptured(e:CameraEvent) : Void
