I have the following code that creates a UIImageView to the same dimensions as a png image stored in the devices photos library:

func getImage(){
        let fileManager = FileManager.default
        let imagePath = (self.getDirectoryPath() as NSString).appendingPathComponent("\(word.components(separatedBy: "::")[0]).png")
        print("imagePath in getImage in DetailWord is: \(imagePath)")
        if fileManager.fileExists(atPath: imagePath){
            self.wordImage.image = UIImage(contentsOfFile: imagePath)
            save.isEnabled = false
            clear.isEnabled = true
            share.isEnabled = true
            wordImage.frame = .init(origin: CGPoint(x: (768 / 2) - (wordImage.image!.size.width / 2), y: (924 / 2) - (wordImage.image!.size.height / 2)), size: wordImage.image!.size)
            tempImage.frame = .init(origin: CGPoint(x: (768 / 2) - (wordImage.image!.size.width / 2), y: (924 / 2) - (wordImage.image!.size.height / 2)), size: wordImage.image!.size)
            self.view.addSubview(tempImage)
            self.view.addSubview(wordImage)
        } else {
            print("No Image")
            wordImage.image = nil
            save.isEnabled = false
            clear.isEnabled = false
            share.isEnabled = false
        }
    }

The code does the task of creating a UIImageView centered in the UIViewController, which exactly encapsulated the png image dimensions. However, when I tap on the png image or one of the coloured pencils (as you can see in the linked screen dumps) and draw on the png image, the image resizes itself (as in the second screen dump).

I can't seem to see anything about this when I use a search engine.
