New Post: Photoshop high pass filter

After updating to your latest version, I tried both,

image.SetArtifact("convolve:bias", "50%");

and the new MorphologySettings

var settings = new MorphologySettings();
settings.Kernel = Kernel.DoG;
settings.KernelArguments = "0,0,2";
settings.ConvolveBias = new Percentage(50);
image.Morphology(settings);

Unfortunately, for both examples, I only get a white image as a result which differs from the command line call.

Do you have any idea?

Thanks again
