Mini_magick

I have setup ImageMagick and mini_magick. Generally speaking, I’m
impressed. The problem seems to be that, unless I’ve missed
something, there is not a lot of documentation detailing the use of
mini_magick. I’ve figured out that one can create an image object
instance from a file with something like:

image=MiniMagick::Image.from_file(‘path_to_file’)

and then work with it (e.g., image[:width]).

I’m wondering if there are other sources that I can use for creating
an image object. For example, could I source my object across the net
with something like:

image=MiniMagick::Image.from_net(‘url_to_image’)

Thanks for any input.
