The problem is

iw.DrawDrawing(0, 0, old_size.cx, old_size.cy, resultpaint);

creates very deep recursion in Drawing definition (other drawing within drawin is stored as operation). That results in slow speed and huge VM.

Mirek

What another method will be more faster than DrawDrawing? May be DrawImage?

You are limited here by the speed of DrawLine.

Anyway, 3000 points sounds like quite a lot for rubber-band. Maybe you could try to simplifify it a bit?

Mirek

I want to understand how can I optimized in drawing and to use in future! In future I can have a control that Paint will have more operations and will be more optimized to save image and set it in Paint method.
