Why, a custom draw in TImage's Canvas it's resistant to the Refresh
procedure, and TPaintBox's Canvas not?
I'm looking for a way to use TPaintBox's  Canvas.Arc, MoveTo, LineTo ....
because it's incredibly fastest that Timage's  Canvas equivalents..., but i
need the TImage's Canvas functionality...
should I try with a Canvas dynamically created, work with it and then assign
it to a TImage???

Do you have your code in a handler for the OnPaint event of the TPaintBox in

No, i havn't.
I currently work in this way:

procedure ButtonClick.....
   with PaintBox.Canvas do
   begin
      Rectangle(....
      LineTo(...
   .....
   end;
   self.Refresh;  TPaintBox.Canvas is cleaned // Draw performance in a
for/repeat structure is good

but, in this case

procedure ButtonClick.....
   with Image.Canvas do
   begin
      Rectangle(....
      LineTo(...
   .....
   end;
   self.Refresh;  TImage.Canvas isn't cleaned // Draw performance in a
for/repeat structure is too slow

the code should be in the OnPaint handler in order for the effects to appear
persistent.
