6 First you use draw, which is used in convert, and then you speak of display.
7 The latter is there to – well – display an image. My understanding of IM
8 mechanics is basic, but just this evening I was working on a small IM-based
9 script of my own.

11 Drawing is done on a canvas. So unless you start with an existing image file
12 as a basis, IM needs to pick a default background colour, which in your case
13 seems to be black.
