How to keep pen width constant in GDI+

Hello!
 
I have the following piece of code:
 

Pen pen(Color(255,0,0,255);
pen.SetWidth(3);
    
m_graphics->ScaleTransform(0.1, 0.1);
m_graphics->DrawLine(&pen, 0, 0, 100, 100);

 
The problem is, that line with also going transformation, so instead of having line with 3 I am having line width 0.3, converted by system to 1.
 
Is there any way to ignore transformation of line with?
 
Thanks!
