Kingfisher: RoundCornerImageProcessor doesn't work on image insde of collectionviewcell - tvOS

[stijnwesterhof]

I have an imageview inside of a collectionview cell. I tried a few processors and they work, but the RoundCornerImageProcessor doesn't work for me..
let processor = RoundCornerImageProcessor(cornerRadius: 20) imageView.kf.setImage(with: url, placeholder: nil, options: [.processor(processor)])

It works for me well, at least in the demo app.

Any more information?

@onevcat I wish that I could give you more information, but the fact is every processor works for me except the rounded image. But when I have an imageview outside of a collection view cell then the roundedcorner processor does work properly..

Maybe take a look at the demo app in Kingfisher, which is also using image view within a collection cell.

Could it be related to this? https://github.com/onevcat/Kingfisher/blob/master/Demo/Kingfisher-Demo/CollectionViewCell.swift#L37

@onevcat sadly enough it's not related to it. I had these properties already

[onevcat]

Can you build a sample app which could reproduce it? I'd like to have a look at it if there is a way to reproduce on my side.

Sorry for the late reaction. The problem was that the size of the image wasn't right to accomplish what I wanted. So I needed a resize processor as well.

let processor = ResizingImageProcessor(targetSize: CGSize(width: 300, height: 300)) >> RoundCornerImageProcessor(cornerRadius: 150)
imageView.kf.setImage(with: url, placeholder: nil, options: [.processor(processor)])

This works, but it shows the shadow behind the collectionviewcell, which is not that nice :(

[onevcat]

Good to know that.

You mentioned about the shadow, which I guess is added by UIKit of tvOS to show a focus indicator?

It seems we do not have much to do with it since it is a system behavior and a almost a black-box to us. :(

Maybe it would be better to use a small round-corner image instead of a fully round image to get a nice visual effect.

@stijnwesterhof Nice man!

If someone uses it:

extension UIImageView {
    func download(url: String?, rounded: Bool = true) {
        guard let _url = url else {
            return
        }
        if rounded {
            let processor = ResizingImageProcessor(referenceSize: self.frame.size) >> RoundCornerImageProcessor(cornerRadius: self.frame.size.width / 2)
            self.kf.setImage(with: URL(string: _url), placeholder: nil, options: [.processor(processor)])
        } else {
            self.kf.setImage(with: URL(string: _url))
        }
    }
}
