I was reading through some of the examples, and I am confused as to why there are 7 ways to make a solid black image:

Maybe I am missing the point of the "canvas"? But what I'm imagining is that you just want a solid background to start working on, so why would you need to use one of those methods over another?

Anthony was just being thorough and trying to show there are many ways to skin the cat.

If you just want a black background and know the size you need, then just do

convert -size WIDTHxHEIGHT xc:black blackimage.png

(or any other suffix you want)

haha ok, thats the one that made the most sense, so I'll just stick with that.

Most of the other methods are to take an existing image and turn it into a black canvas that is the same size.

This is only important when writing a IM command so it can handle an image that is ANY SIZE, and not limit the command to a specific sized image.
