Have you looked at the Bitmap section (http://www.codeguru.com/Cpp/G-M/bitmap/) ? There are many articles there that explain how to save a screen image.

You can use GDI+ instead,at first you can drawing your shapes on EMF Plus,then:
Image* image = new Image (L"xxx.tmp", TRUE);

#ifdef _UNICODE
CString lpwstr = strFileName;
#else if
LPWSTR lpwstr = A2W(strFileName);
#endif

CLSID encoderClsid;
Status stat;


// Get the CLSID of the BMP encoder.
if (GetEncoderClsid(L"image/bmp", &encoderClsid) != -1)
stat = image->Save(lpwstr, &encoderClsid, NULL);

Then you can convert it to bitmap.
