Canvas - Scale / Zoom

[andyhill]

I am using UniCanvas (cArea) and want to zoom / scale display (experimental code below does nothing), please advise how - Thanks in advance.

    case ScaleMode of
      0: begin
           cArea.BeginUpdate;
           cArea.ScaleBy(1, 1);
           cArea.EndUpdate;
         end;
      1: begin
           cArea.BeginUpdate;
           cArea.ScaleBy(10, 10);
           cArea.EndUpdate;
         end;
    end;

Hello,

For reference, scaling works differently, you can read about it here:

Thanks Sherzod, I was thrown by the IDE showing the canvas had a built in method for scaling 😞

It draws a frame around the canvas (I need to remove it) ?
