-====== CameraView control ======
-===== Description =====
-Create a camera preview control using the **CreateCameraView** function of the [[built_in:app|app]] object:
-<code>cam = app.CreateCameraView( width, height, options );</code>
-This control allows your program to show a live feed of what is currently being seen by the phone/tablet's camera. If your device has a front facing camera and is at least version 2.3 of Android you can use the **"Front"** option to show the front camera's preview.
-You will need to call the **StartPreview** function of the CameraView control to start the preview\\ (Note: On some phones it is neccessary to wait at least one second before calling the StartPreview function).
-<code>cam.StartPreview();</code>
-Use the **TakePicture** function to take a picture and save it to a given location.
-<code>cam.TakePicture( filename );</code>
-Use the **SetPictureSize** function to set the dimensions in pixels of the pictures taken (eg. 1024 x 768).
-<code>cam.SetPictureSize( width, height );</code>
-For more sophisticated examples including motion detection and video streaming, check out the **'Camera Stream'**, **'Camera Snap'** and **'Camera Motion'** sample programs in the DroidScript samples section.
