That’s exactly what I do, except the problem is the base image of the prototype/contraption will be fixed. If I resize the contraption, and the image started at (200,200) after instantiation, it remains at (200,200). It cannot be changed. I’ve tried on view or a subordinate widget that tries to resize it - it stays fixed.
Then, when I composite the subordinate canvases into it, and the contraption is resized, the image will wrap. The image will not resize itself and I can’t force it to resize.
The only way I have gotten around this is by maximizing the card on the prototype page so it starts with a very large image buffer, and then shrink it on view, when it’s actually instantiated. Except, that has problems, too.
So, I figure the only real fix is to not draw on the prototype’s/contraption’s base image, but on a canvas, and show the canvas.
