Image.Load<TPixel>(imageSource.Invoke(), out IImageFormat imgFormat); Alternative

[TonyValenti]

I currently have this code:

var image = Image.Load<TPixel>(imageSource.Invoke(), out IImageFormat imgFormat);

In the latest version of ImageSharp, this method has gone away.

What is the right way for me to determine the image format of the image?

Specifically, I only need to know if the loaded image is transparent or not.

we got rid of the out overloads, that information is now available in the images metadata image.Metadata.DecodedImageFormat if you need both the image and the format.

If you just want the format that can be done using the Image.DetectFormat(...)/Image.DetectFormatAsync(...) APIs

or if you can call Image.Identify(..) / Image.IdentifyAsync(..) too if you want the metadata also, then like Image.Load..(..) you access it from foo.Metadata.DecodedImageFormat

This change was introduced to allow both our async and sync apis to have and identical signatures to normalise the patterns you have to follow to get those details.

Thanks so much!

Yes. Out sucks. Definitely prefer this method.
