The +plugin provides access to the API functionality for camera settings and +capturing an image. + +Most of the QML code supports the user interface for this application with the +Camera elements being mostly found in \i {declarative-camera.qml} and +\i {CaptureControls.qml}. + +In \i {declarative-camera.qml} the Camera element is initialized with an id +of \i {camera }, a photo preview is setup, states are implemented for image +preview or capture and a CaptureControls element is initialized. The initial +\i state is \i PhotoCapture. The camera element includes a handler, \i onImageCaptured, +for the \l {imageCaptured} signal. The handler sets up the application to process +the preview including a change in the user interface state. The PhotoPreview +element now becomes visible with any key press being picked up by the handler +in PhotoPreview and returning the state to \i PhotoCapture. + +The \i CaptureControls element, which is implemented in \i {CaptureControls.qml}, +generates a column on the right hand side of the screen which includes control +buttons for \i focus (not initially visible), \i {capture}, \i {flash modes}, +\i {white balance}, \i {exposure compensation}, and if a preview is +available a \i {preview} button. The last button exits from the application. + +When the Capture button is pressed the \i onClicked handler calls +\l {Camera::captureImage()}{captureImage()} + + + + + + + +*/ |
