Rectangle bringing on camera in ZBar scanner? - iphone

Question

How can we bring rectangle on camera for barcode scanning like red laser with scanningound? is there any built in property?I tried following:
reader.readerView.tracksSymbols = YES;
reader.readerView.trackingColor = [UIColor redColor];
[reader setShowsZBarControls:NO];
reader.readerView.tracksSymbols = TRUE;
scanner.accessibilityFrame = CGRectMake(100, 100, 200, 300);

Answer 1

Add the rectange as an overlay on your camera view.Here is the code:
- (IBAction) scanButtonTapped
{
// ADD: present a barcode reader that scans from the camera feed
ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;
ZBarImageScanner *scanner = reader.scanner;
reader.showsZBarControls = NO;
[scanner setSymbology: ZBAR_I25
config: ZBAR_CFG_ENABLE
to: 0];
// present and release the controller
[self presentModalViewController: reader
animated: YES];
reader.cameraOverlayView = [self CommomOverlay];
[reader release];
}
-(UIView*)CommomOverlay{
UIView* view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,480)];
UIImageView *FrameImg = [[UIImageView alloc] initWithFrame:CGRectMake(70,160,203,180)];
[FrameImg setImage:[UIImage imageNamed:#"overlaygraphic.png"]];
[view addSubview:FrameImg];
return view;
}
hope this will help you..:)

Did you try
reader.cameraOverlayView = overLayView;
?? i.e cameraOverlayView property of UIImagePickerController.
There you can set what ever you want. Hope this is what you want.
