GDIplus & Windows Scale ui %

[kamesankamesan]

Hi,
My screen is a 2560x1440.
My windows ui scale is 125% 
I'm trying to draw a yellow rectangles on viewport area.
But my drawing area seems based on the 125% virtual resolution of 2048x1152
So rectangles are cropped.

here my code part:
 

Local $scale = _WinAPI_EnumDisplaySettings('', $ENUM_CURRENT_SETTINGS)[0] / @DesktopWidth
    _GDIPlus_Startup()
    Local $hDC = _WinAPI_GetDC($GE_Pos)
    Local $hPen = _GDIPlus_PenCreate(0xFFFFA500, 2) ; Format de couleur ARGB (Alpha, Rouge, Vert, Bleu)
    Local $rect = WinGetClientSize($GE_Pos)
    Local $hGraphics = _GDIPlus_GraphicsCreateFromHDC($hDC)
   _GDIPlus_GraphicsDrawRect($hGraphics, ($Lpos[0]+$GE_Pos[0]+$Title_X_Tweak+2)*$scale, ($Lpos[1]+$GE_Pos[1]+$Title_Y_Tweak+2)*$scale, ($GE_Pos[2] - 4)*$scale, ($GE_Pos[3] - 4)*$scale, $hPen)    
   _GDIPlus_GraphicsDispose($hGraphics)
    _GDIPlus_PenDispose($hPen)
    _WinAPI_ReleaseDC($GE_Pos, $hDC)
    _GDIPlus_Shutdown()

i'm biting my head.
Any help is welcome.

Just pick the resolution you enjoy most at 100%. This is what I did.  And all your DPI and scaling issues will be resolved.  But if you insist on keeping your 125%, search for DPI awareness threads on this forum, there are numerous discussions of this topic.

Thank you.
Unfortunately there are several users with different ui scales. My rectangles should be able to draw according to any ui scale %
