If you need an easy way to allow your current code to still work, you can u=
se canvas.backdrop as a stand-in for the old canvas.graphics

Add a module to your project and add a global method:

Public Function graphics(extends c As Canvas) as Graphics
  If c.Backdrop=3DNil Then c.Backdrop=3DNew Picture(c.Width,c.Height)
  c.Invalidate
  Return c.Backdrop.Graphics
End Function

This works in 2018r4 but I wouldn't guarantee it in the future.

You can also add checks for the width and height matching and maybe create =
a new picture and draw the current one into it and then swap the new one in=
 if the size changes but I just wanted to give you a simple solution.

Should at least get you going until you can get away from the old way of do=
ing it.
