Native png encoder not working in 14.1

[andreas-eriksson]

I have a small benchmark that stopped working after updating from 14.0 to 14.1/14.2 There seems to be a problem with the native png encoder.

using BenchmarkDotNet.Attributes;
using PhotoSauce.MagicScaler;
using PhotoSauce.NativeCodecs.Libjpeg;
using PhotoSauce.NativeCodecs.Libpng;

namespace Test.Benchmarks;

public class MagicScalerBenchmarks
{    
    [Benchmark]
    public void Crash()
    {
        CodecManager.Configure(codecs =>
        {            
            codecs.UseLibpng();
        });

        var settings = new ProcessImageSettings
        {
            Width = 400
        };
        settings.TrySetEncoderFormat("image/png");

        MagicImageProcessor.ProcessImage("image.png", new MemoryStream(), settings);
    }
}

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

That would be the result of using an older codec version. You need to update all codec plugins when you update the main library, as they use some internal APIs that are not stable between releases.

Ahh, I forgot about them as they are available as preview versions. Sorry about that.
