Replacement for UIView's contentStretch?

由 流过昼夜 提交于 2019-11-30 14:52:21
In iOS 6.0 the contentStretch property of UIView was deprecated. How can I achieve the same functionality with new/old/other API? The functionality I am looking for is stretching just part of an image (everything but the edges) on a UIButton. Use resizableImageWithCapInsets and UIEdgeInsets to make a stretching UIButton background image. For example: UIImage* image = [UIImage imageNamed:@"image.png"]; image = [image resizableImageWithCapInsets:UIEdgeInsetsMake(0, 20, 0, 20)]; [button setBackgroundImage:image forState:UIControlStateHighlighted]; I don't think you can stretch more than one pixel

Difference between contrast stretching and histogram equalization

由 江枫思渺然 提交于 2019-11-30 05:07:33
I would like to know the difference between contrast stretching and histogram equalization . I have tried both using OpenCV and observed the results, but I still have not understood the main differences between the two techniques. Insights would be of much needed help. Lets Define Contrast first, Contrast is a measure of the “range” of an image; i.e. how spread its intensities are. It has many formal definitions one famous is Michelson’s: He says contrast = ( Imax - Imin )/( Imax + I min ) Contrast is strongly tied to an image’s overall visual quality. Ideally, we’d like images to use the

I have a UIImageView where I have set the frame size to x = 0, y = 0, width = 404, height = 712 . In my project, I need to change the image in UIImageView dynamically. I am using this code to change the image: self.imageView.image = [UIImage imageNamed:@"setting-image.png"]; The problem is, when the *.png image size is smaller than the UIImageView frame size, the image stretches. I don't want it to stretch. Is there any way to do that? jtbandes You can use self.imageView.contentMode = UIViewContentModeScaleAspectFit; Swift 3: imageView.contentMode = .scaleAspectFit Or UIViewContentModeCenter /
