Setting Background color of a MagickWand

[Sargis]

Is there a way to set the background color of a magickwand that has multiple images so that when montaged to a thumbnail size that isnt NxN but is instead MxN, the area that the image doesnt fill is filled with the background color? Or does the background color have to be set after the montage operation is done?

Thanks,

Sargis

Note Images will only fill a NxN area only if they have a square aspect ratio. Most images don't the parts they don't fill will be filled in by montage with whatever background it is using. What it used depends on the options in use. See IM Examples , Montage for examples of what montage does with various options.
