Resizing Image With InfoOptions not work

[lucio1392]

I have to tried this way to cache and download image with InfoOptions but it's not work well like when I'm using

thumbnailImageView.kf_setImageWithURL(<#T##URL: NSURL?##NSURL?#>, placeholderImage: <#T##Image?#>, optionsInfo: <#T##KingfisherOptionsInfo?#>)

InfoOptions parameter passing not working at least with Transaction Option. When I scrolling my tableview cell, look like image replacing not exactly.

I provide my code below. Please help me. Thank.

`
let imageManager = KingfisherManager.sharedManager

let keyForCaching = NSURL(string: thumbnailImage)?.absoluteString

        let infoOptions : KingfisherOptionsInfo = [.Transition(.Fade(2.0)),
                                                   .ForceTransition]

        imageManager.cache.retrieveImageForKey(keyForCaching!, options: infoOptions, completionHandler: { (imageCached, _) in
            if let image = imageCached {
                self.thumbnailImageView.image = image
            }else{
                self.imageManager.downloader.downloadImageWithURL(NSURL(string: thumbnailImage)!, options: infoOptions, progressBlock: nil, completionHandler: { (image, error, imageURL, originalData) in

                    let scaleImage = image?.imageAspectScaledToFillSize(CGSize(width: 375, height: 185))

                    self.imageManager.cache.storeImage(scaleImage!, forKey: keyForCaching!)

                    self.thumbnailImageView.image = scaleImage

                })
            }
        })

The transition option only works when you use the image extension methods of Kingfisher. Instead of checking the cache of manager, just use the imageView.kf_setImage methods will apply the transition effect.

I could understand that you need to cache the resized images before storing it. It is a feature in plan and will be implemented soon. Currently, you might do the transition yourself if you are using the imageView setter method directly.

Thank for quick reply. I have 1 more question.

Do you mean only transition option work with image extension methods of Kingfisher or any others options like BackgroundDecode or CacheMemoryOnly have same ?

All options work with image extensions. But usually the default values are good enough (except for the transition style), so there is no need to set them explicitly unless you really need.
