Re: Set "compose:clamp" to "off"
Thanks for your advice. HDRI version of Magick.NET realy solves the problem. Clamping can be set to off with SetArtifact method of MagickImage class. Final result:
public MagickImage HighPass(MagickImage src, double radius = 2)
{
MagickImage dst = (MagickImage)src.Clone();
dst.GaussianBlur ...
public MagickImage HighPass(MagickImage src, double radius = 2)
{
MagickImage dst = (MagickImage)src.Clone();
dst.GaussianBlur ...
