I’ve tested the BitmapScalingMode but could not see any better result with maximum quality (Fant, Fantastic) to HighQuality. Now I see the values behind are the same. this is an bug of Microsofts Framework?
// Set the bitmap scaling mode for the image to render faster.
RenderOptions.SetBitmapScalingMode(MyImage, BitmapScalingMode.LowQuality);
FantandHighQualityare synonyms, as indicated in the documentation…So no, it’s not a bug. It works as designed.
