How to draw a clear line at an angle?

Question

Delphi

I use C++ Builder XE
To create a brush I use the function

TLogBrush lb = {BS_SOLID, RGB(91,155,213), 0};
   FPen = ExtCreatePen(PS_GEOMETRIC | PS_ENDCAP_SQUARE , 8, &lb, 0, 0);

I draw a line at an angle, and protrusions are obtained from its sides, how to remove them?

MoveToEx(FDC, 0, 0, 0);
  LineTo(FDC, 300, 450);

Google what antialiasing is. The simple answer is no way - you won't rotate the pixels.
