IOS Implementation Rotate To Portrait mode

[Derek]

I Have seen some people looking for The oned IOS ZXING SCANNER for
Portrait mode.

If you add this code to ZXingWidgetController controller and comment
out //self.oneDMode = isOneDModeEnabled; and then adding the red line
to the view in the overlay view it works well.

CGRect cropRect = [overlayView cropRect];
/*
if (oneDMode) {
// let's just give the decoder a vertical band right above the red
line
cropRect.origin.x = cropRect.origin.x + (cropRect.size.width / 2) -
(ONE_D_BAND_HEIGHT + 1);
cropRect.size.width = ONE_D_BAND_HEIGHT;
// do a rotate
CGImageRef croppedImg = CGImageCreateWithImageInRect(capture,
cropRect);
capture = [self CGImageRotated90:croppedImg];
capture = [self CGImageRotated180:capture];
// UIImageWriteToSavedPhotosAlbum([UIImage
imageWithCGImage:capture], nil, nil, nil);
CGImageRelease(croppedImg);
cropRect.origin.x = 0.0;
cropRect.origin.y = 0.0;
cropRect.size.width = CGImageGetWidth(capture);
cropRect.size.height = CGImageGetHeight(capture);
}
*/

// N.B.
// - Won't work if the overlay becomes uncentered ...
// - iOS always takes videos in landscape
// - images are always 4x3; device is not
// - iOS uses virtual pixels for non-image stuff

{
float height = CGImageGetHeight(capture);
float width = CGImageGetWidth(capture);

CGRect screen = UIScreen.mainScreen.bounds;
float tmp = screen.size.width;
screen.size.width = screen.size.height;;
screen.size.height = tmp;

cropRect.origin.x = (width-cropRect.size.width)/2;
cropRect.origin.y = (height-cropRect.size.height)/2;
}

CGImageRef newImage = CGImageCreateWithImageInRect(capture,
cropRect);
CGImageRelease(capture);
//************NEW CODE****************//
int backCameraImageOrientation = UIImageOrientationRight;

UIImage *scrn = [[UIImage alloc] initWithCGImage:newImage scale:
(CGFloat)1.0 orientation:backCameraImageOrientation];
//************NEW CODE****************//
//************COMMENT OUT***************//
//UIImage *scrn = [[UIImage alloc] initWithCGImage:newImage];

CGImageRelease(newImage);
Decoder *d = [[Decoder alloc] init];
d.readers = readers;
d.delegate = self;
cropRect.origin.x = 0.0;
cropRect.origin.y = 0.0;
decoding = [d decodeImage:scrn cropRect:cropRect] == YES ? NO : YES;
[d release];
[scrn release];
}
