Hi,
I am using filter in my project.
When I load image from gallery and apply filter then it works fine. But when I capture an image and apply the filter then it gives me strange result. Captured image gets rotated left by 90 degrees.
It will be helpful if someone can suggest me a better solution. I am using swift version 1.2
Thank you
I struggled a bit and found the solution. When you capture images from camera then default orientation is landscape perhaps that was causing the trouble. I just used following swift extention and it worked fine for me.
extension UIImage {
func fixOrientation() -> UIImage {
if self.imageOrientation == UIImageOrientation.Up {
return self
}
UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
self.drawInRect(CGRectMake(0, 0, self.size.width, self.size.height))
let normalizedImage:UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return normalizedImage;
}
}
and to use it with image:
let capturedImage = //image picked using picker
let orinentationFixedImage = capturedImage.fixOrientation()
THANKYOU, im currently building my own social app, and for the LONGEST time this has been an issue. THANK-YOU

you need the set output.connection(with: .video)?.videoOrientation before capture image
if let orientation = AVCaptureVideoOrientation(rawValue: UIDevice.current.orientation.rawValue) {
camera.output.connection(with: .video)?.videoOrientation = orientation
}
