First you use draw, which is used in convert, and then you speak of display.
Please see the attached menu capture for "Image Edit ..."
The latter is there to – well – display an image. My understanding of IM
mechanics is basic, but just this evening I was working on a small IM-based
script of my own.
If you left-click on the window, you get a menu that allows the full
range of editing capabilities.
Drawing is done on a canvas. So unless you start with an existing image file
as a basis, IM needs to pick a default background colour, which in your case
seems to be black.
Yes, the problem is, I AM using an existing image. Usually, with IM's
display(1), I could add lines and text to images but now, all of a
sudden, it uses a bounding box around the new strokes, choosing a single
random color from the background.
There's lots of USE flags associated with Image Magick, most of which I
have no clue about. Perhaps I need some transparency support or something.
and can find nothing in the internet about it.
Have you tried the IM website?
