Re: Using GDI+ from MFC C++ ???

This code compiles fine with VS2008 SP1 (note that
GetEncoderClsid body is required):

<code>

#include <windows.h>
#include <gdiplus.h>
#include <stdio.h>
using namespace Gdiplus;

#pragma comment(lib, "gdiplus.lib")

int GetEncoderClsid(const WCHAR* format, CLSID* pClsid)
{
   UINT num = 0; // number of image encoders
   UINT size = 0; // size of the image encoder
array in bytes

   ImageCodecInfo* pImageCodecInfo = NULL;

   GetImageEncodersSize(&num, &size);
   if(size == 0)
       return -1; // Failure

   pImageCodecInfo = (ImageCodecInfo*)(malloc(size));
   if(pImageCodecInfo == NULL)
       return -1; // Failure

   GetImageEncoders(num, size, pImageCodecInfo);

   for(UINT j = 0; j < num; ++j)
   {
       if( wcscmp(pImageCodecInfo[j].MimeType, format) ==
0 )
       {
           *pClsid = pImageCodecInfo[j].Clsid;
           free(pImageCodecInfo);
           return j; // Success
       }
   }

   free(pImageCodecInfo);
   return -1; // Failure
}

INT main()
{
   // Initialize GDI+.
   GdiplusStartupInput gdiplusStartupInput;
   ULONG_PTR gdiplusToken;
   GdiplusStartup(&gdiplusToken, &gdiplusStartupInput,
NULL);

   CLSID encoderClsid;
   Status stat;
   Image* image = new Image(L"Bird.bmp");

   // Get the CLSID of the PNG encoder.
   GetEncoderClsid(L"image/png", &encoderClsid);

   stat = image->Save(L"Bird.png", &encoderClsid, NULL);

   if(stat == Ok)
       printf("Bird.png was saved successfully\n");
   else
       printf("Failure: stat = %d\n", stat);

   delete image;
   GdiplusShutdown(gdiplusToken);
   return 0;
}
