How to use -ordered-dither in magickwand?

Is there an alternative, or a way to get similar results?

We'll need to add a method to the MagickWand API for ordered dither. For now, you must call the MagickCore method OrderedPosterizeImageChannel() directly to perform ordered dithering.

ImageMagick 6.3.1-7 Beta has the new MagickOrderedPosterizeImage() method. It will be available tommorrow. To use MagickCore within MagickWand, simple extract the image with GetImageFromMagickWand(), operate on it with MagickWand, then put in back in a wand container with NewMagickWandFromImage().

great, I'll try that tomorrow then....

could you please let me know how to do masks with magicwand? Is that possible?

1. I'll open a pic
2. create let's say rectangle with rounded edges which will be the mask for the pic

I see it's pretty easy to do via command line when using -matte....but couldn't figure it out how to do that via magicwand.
