Breaking changes 7.17 > 7.20

[ghost]

I updated the nuget from 7.17 to 7.20 and there are some code breaking changes. (not expected from versioning number).

Can someone please point me how to do the following as of now (didn't find any information)

+ Cloning a magickImage ?
the method "Clone()" has gone totally
IMagickImage image = rawImage.Clone())

+ Setting the image background
image.BackgroundColor = new MagickColor(MagickColors.Transparent);

+ reading using a stream and settings
method gone as well
image.Read(Stream content, MagickReadSettings settings);

eg, for eps, i need to set a density in the read settings before reading the strem...
MagickReadSettings settings = new MagickReadSettings { Density = new Density(300, 300, DensityUnit.PixelsPerInch) };

Thanks !!

You might be expecting semver but in the documentation (https://github.com/dlemstra/Magick.NET) you can find the version strategy that explains this.

The return type of rawImage.Clone() depends on the type you used for rawImage. I suspect you are using IMagickImage. The type has changed to IMagickImage<QuantumType> where QuantumType depends on the version of the package that you are using. Q8 = byte, Q16 = ushort and Q16-HDRI = float. You will need to change that to IMagickImageor usevar` where possible to avoid issues. You are experiencing the same issue in all those places that you mention.

Thanks Dirk.

Versionning makes sense indeed.
Dunno why we used the interface ImagickImage instead of the MagickImage class in our code, i just changed it and all good.

Cheers,
