Incomprehensible compilation error for Gdiplus::Matrix() constructor

Question

From the documentation

Syntax

C++

void Matrix();

From gdiplusmatrix.h:

 Matrix()
    {
        GpMatrix *matrix = NULL;

        lastResult = DllExports::GdipCreateMatrix(&matrix);
    
        SetNativeMatrix(matrix);
    }

From my source code

Gdiplus::Matrix * matrix = new Gdiplus::Matrix();

From the compilation

1>C:\Users\admin\OneDrive\Projects\Patterns\Pattern1\Patterns1\Patterns1Dlg.cpp(370,56): error C2660: 'Gdiplus::GdiplusBase::operator new': function does not take 3 arguments

1>C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\um\GdiplusBase.h(30,12): message : see declaration of 'Gdiplus::GdiplusBase::operator new'

The first error message refers to my use of new Gdiplus::Matrix().

The second error refers to the line

 void* (operator new)(size_t in_size)
    {
       return DllExports::GdipAlloc(in_size);
    }

So, why is this failing and how do I fix it?

It seems that you are using MFC. If GDI+ is needed, then try this:

Gdiplus::Matrix* matrix = ::new Gdiplus::Matrix( );
. . .
::delete matrix;

// or:

Gdiplus::Matrix matrix;
