GDI CreateElliptic

[Damein]

So I've got an image that is a circle and I want to be able to detect when the inside of the circle is clicked. I've used

 

If _WinAPI_PtInRectEx($aPos[0], $aPos[1], $TargetX + 5, $TargetY + 30, $TargetX + $TargetWidth, _
            $TargetY + $TargetHeight) Then

 

And that works but since its a circle it won't work. I attempted to use the CreateEllipticRgn using the following but my script crashes instantly.

 

Dim $Range = [100, 100, 100, 100]

_WinAPI_CreateEllipticRgn($Range)

 

Not sure if I have the structure right (I doubt I do) but if there's an easier method to detect a mouse click within a circle than that would be helpful. Thanks!

Hi,

x²+y²=r² so the distance of a point X from the middle of a circle M is 

if XM<r the point is inside the circle...
