}We can look at this. Is this something that's been reported elsewhere?consider switching back to GDI rendering because of area series drawing bugs with GDI+ rendering
Our understanding is that you can call those functions as many times as you wish if calls do not "cross boundaries" (essentially solutions 2 & 3 in the list provided by Microsoft):Do not call GdiplusStartup or GdiplusShutdown in DllMain or in any function that is called by DllMain. If you want to create a DLL that uses GDI+, you should use one of the following techniques to initialize GDI+:
- Require your clients to call GdiplusStartup before they call the functions in your DLL and to call GdiplusShutdown when they have finished using your DLL.
- Export your own startup function that calls GdiplusStartup and your own shutdown function that calls GdiplusShutdown. Require your clients to call your startup function before they call other functions in your DLL and to call your shutdown function when they have finished using your DLL.
- Call GdiplusStartup and GdiplusShutdown in each of your functions that make GDI+ calls.
