CMYK to sRGB gives washed out image

[LennardF1989]

I have a TIF file in CMYK (CoatedFOGRA39) and wish to convert that to sRGB (IEC61966-2).

When I do this using the commandline: convert ZDCF0757.tif -profile CoatedFOGRA39.icc -profile "sRGB Color Space Profile.icm" -strip test.png I get the output I expect.

However, when I try to replicate this inside Magick.NET, it comes out washed out.

using var magic = new MagickImage(input);

magic.Format = MagickFormat.Png;

magic.SetProfile(ColorProfile.CoatedFOGRA39);
magic.SetProfile(ColorProfile.SRGB); //NOTE: Also tried manyally loading the ICC file to be absolutely sure

magic.Strip();

magic.Write(outputStream);

I have been toying with the settings for over 2 hours now and it's driving me nuts :P Who can point out what I'm missing?

Attached is the original TIF and the output of both ImageMagick and Magick.NET with the code above.

It looks like you are using an older version of Magick.NET? I cannot reproduce your issue with the latest version. You might also want to change your code to use magic.TransformColorSpace(ColorProfile.CoatedFOGRA39, ColorProfile.SRGB); incase another input image has a color profile.

I've tried to use the TransformColorSpace, but it gave the same result. The attached files have been generated with the latest NuGet package (Q8, but also tried Q16 - AnyCPU, 7.20.1) - which specific version are you using? @dlemstra

EDIT: Additionally: I'm using Windows.

I was using the latest development build and I think that it still uses the same version of ImageMagick as when I published the new release. Will check it tonight.

I am unable to reproduce your issue. I tried the following:

<PackageReference Include="Magick.NET-Q8-x64" Version="7.20.0.1" />

using var magic = new MagickImage("ZDCF0757.tif");

magic.Format = MagickFormat.Png;

magic.TransformColorSpace(ColorProfile.CoatedFOGRA39, ColorProfile.SRGB);

magic.Strip();

magic.Write("test.png");

And I get the following output:

Very peculiar. I had the issue constantly yesterday, as is evident by the output in the ZIP. But now, it just works... Thanks for checking and confirming!
