Image frame count

[danielebogo]

@onevcat Is it possible to store the animated image frame count when an animated image is created?

When func animatedImage(data: Data, options: ImageCreatingOptions) -> KFCrossPlatformImage? is called, the GIFAnimatedImage has the images array populated, so it's easy to just store the frame count.

If the no preloadAll or onlyFirstFrame is used, then we can retrieve the same info from the imageSource with CGImageSourceGetCount(imageSource).

SDWebImage has this value stored in the image and it's retrieved by each decoder.

I can push a PR if necessary.

Thanks for it. #1647 has been merged and a new version (6.2) was released for this.

Yes, it's possible to store the animated image frame count. When animatedImage(data:options:) is called, you can store the frame count from the populated images array. If noPreloadAll or onlyFirstFrame is used, you can retrieve the frame count using CGImageSourceGetCount(imageSource). This approach is similar to how SDWebImage handles it. A PR would be appreciated. dooflixapk

Hi @onevcat,

Is there a way to store the frame count of an animated image when the image is created? I’m looking for a method to access or cache this information efficiently within the framework.

Thanks for the help! Apne tv

If you get the image loaded by Kingfisher (say, the setImage extension method of image view or the retrieveImage method in the KingfisherManager), the retrieved image should contain a imageFrameCount under the kf namespace. So I guess you can access it as:

let count = image.kf.imageFrameCount
