Supported Camera Events

RICOH Camera Wireless SDK supports the following camera events:

• imageStored is called when image is stored to the camera storage.
• captureComplete is called when capturing an image is completed.
• deviceDisconnected is called when the camera you’ve already made a connection is disconnected.
• liveViewFrameUpdated is called when live view frame data is updated.

Register Events

Override the virtual method corresponding to the event you want to receive in your derived class of CameraEventListener. You can also see Live View for an example of liveViewFrameUpdated.

class UserEventListener: CameraEventListener {

    func imageStored(sender: CameraDevice, image: CameraImage) {
        print("Image Stored. Image Name: \(image.name)")
    }

    func captureComplete(sender: CameraDevice, capture: Capture) {
        print("Capture Complete. Caputure ID: \(capture.id)")
    }

    func deviceDisconnected(sender: CameraDevice) {
        print("Device Disconnected.")
    }
}

And register the event listener as follows:

let userEventListener = UserEventListener()
cameraDevice.addEventListener(listener: userEventListener)

Registered events are called when corresponding events occur at CameraDevice.
