How to create new MagickImage instance with same settings as another

[toptensoftware]

I'm trying to create some small cropped extracts from a loaded MagickImage image read from a file. Usually these files will be 1, 3 or 4 channels.

How can I create a new MagickImage instance that has the exact same channel/color format as the original image?

fwiw: at the moment, I'm using something like the following but it always creates a 3-channel image whereas I want to keep the same format as another MagickImage instance. (after this I'm using CopyPixels copy the part I'm interested in)

new MagickImage(MagickColors.White, 100, 100);
