iOS ZXingScannerView - BarcodeReader createLuminanceSource-Delegate

[schmittch]

I have made some local modifications on the source in src/ZXing.Net.Mobile/MonoTouch/ZXingScannerView.cs:255 (Master-Branch 2013-06-21 08:51). Please see my comments [schmittch Mod 2013-07-09] below.

            /* ZXingScannerView.cs:254 ... */

            var barcodeReader = new BarcodeReader(null, (img) =>     
            {
                var src = new RGBLuminanceSource(img); //, bmp.Width, bmp.Height);

#if false
/* [schmittch Mod 2013-07-09]: UIDeviceOrientation has more cases
 *                             (Unknown, Portrait, PortraitUpsideDown, LandscapeLeft, LandscapeRight, FaceUp, FaceDown)
 *                             than for the algorithem are interesting. ...

                //Don't try and rotate properly if we're autorotating anyway
                if (options.AutoRotate.HasValue && options.AutoRotate.Value)
                    return src;

                switch (UIDevice.CurrentDevice.Orientation)
                {
                    case UIDeviceOrientation.Portrait:
                        return src.rotateCounterClockwise().rotateCounterClockwise().rotateCounterClockwise();

                    return src;

                    }
                }
#endif

            }, null, null); //(p, w, h, f) => new RGBLuminanceSource(p, w, h, RGBLuminanceSource.BitmapFormat.Unknown));

            /* ... */

Otherwise, a great library!

Thanks, didn't realize this was an available way to check!
