Hi
Hope all is well?
I'm trying to make my own app and have run into my first issue haha
I'm a cinematographer that makes LUTS for cinematographers for many different camera platforms. I also make them for iPhone users so I want to create my own app so they can use them in the phone/app rather then on a computer.
Long story short, LUTS are kinda like filters, Instagram filters etc.....But instead of applying a typical Apple filter like CISepiaTone etc
When the users applies the filters from the app, I need the filter to be applied from a png file not a Apple filter
I know it's possible but I can't seem to find a code that works.
So basically, users import a picture/video from their photo library, they then apply the filter and save it to their phone.
I just need it to apply my own filters from png files not a CI Filter
This is my code so far:
import UIKit
class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
@IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
/
}
func importImage(_ sender: Any) {
let image = UIImagePickerController()
image.delegate = self
image.sourceType = UIImagePickerControllerSourceType.photoLibrary
image.allowsEditing = true
self.present(image, animated: true)
{
/
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage
{
imageView.image = image
}
else
{
/
}
self.dismiss(animated: true, completion: nil)
}
func filterAction(_ sender: Any) {
guard let image = self.imageView.image?.cgImage else { return }
let openGLContext = EAGLContext(api: .openGLES3)
let context = CIContext(eaglContext: openGLContext!)
let ciImage = CIImage(cgImage: image)
let filter = CIFilter(name: "CISepiaTone")
filter?.setValue(ciImage, forKey: kCIInputImageKey)
filter?.setValue(1, forKey: kCIInputIntensityKey)
if let output = filter?.value(forKey: kCIOutputImageKey) as? CIImage {
self.imageView?.image = UIImage(cgImage: context.createCGImage(output, from: output.extent)!)
}
/
}
}
so the last filter action I need to change from a CI filter to filter with my png file
Any ideas? im using Xcode 8.2.1 with Swift
