UIGraphicsBeginImageContext with parameters

Question

I am taking a screenshot in my application. I am able to take the screenshot.

Now I want to take the screenshot by specifying the x and y coordinate. Is that possible?

Answer 1

Here is Swift version

//Capture Screen
func capture()->UIImage {

    UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, false, UIScreen.mainScreen().scale)
    self.view.layer.renderInContext(UIGraphicsGetCurrentContext()!)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image

}
