## Steps to reproduce

1. Download sample and run
2. Tap button

## Expected result

Filter should be applied and the image view should be updated

## Actual result

System.ArgumentException: inputImage is not supported by this filter

## Notes

I have included an Objective-C version of the sample which does work

It has been reported that any iOS 9 specific filter is throwing this error

Comment 2 Sebastien Pouliot 2016-02-05 17:00:49 UTC
Note that your C# sample does not match your ObjC one and will fail (ANE) unless you change it for:

> filter.Image = new CIImage(testImageView.Image.CGImage);
