CameraView control

(Information and examples taken from the DroidScript documentation)

Create a camera preview control using the CreateCameraView function of the app object:

cam = app.CreateCameraView( width, height, options );

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).

cam.StartPreview();

Use the TakePicture function to take a picture and save it to a given location.

cam.TakePicture( filename );

Use the SetPictureSize function to set the dimensions in pixels of the pictures taken (eg. 1024 x 768).

cam.SetPictureSize( width, height );

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.

Some controls use the same methods.
For examples of the same methods look here.

These are the camera resolution options:  

• CIF
• QVGA
• SVGA
• VGA
• XGA
• UXGA
