Answer 1

Since you're drawing from scratch, couldn't you resize you drawing base on zoom factor?

You could multiply your drawing dimensions by your zoom factor. Assuming your zoom factor would be:

• 0.5 for 50 % zoom (which would reduce the drawing size)
• 1.0 for 100% (Real size)
• 1.5 for 150 % (bigger size), you could calc the width this way:

object.Width = originalWidth * zoomFactor;
