Hi all,

I've hit a problem trying to use the GDI+ function MakeTransparent. This function is listed as being a member of Bitmap in MSDN and there are plenty of examples mentioned on the web using it from .NET. However, I'm writing an ActiveX control in MFC and using GDI+ and this method is reported as not being available. The error message is:

error C2039: 'MakeTransparent' : is not a member of 'Gdiplus::Bitmap'

I've never encountered a GDI+ function not being available like this. Does anyone know what's going on?

I'm using VS 2010 on XP SP3

Many Thanks

Tom

This seems written to answer your question ...
Using GDI+ with MFC or native C/C++[^]

Solution 3

Thanks for the responses. It seems the Bitmap class exposed in .NET is simply different to that which is exposed by GDI+.
