Posterize example for C++ Builder

This example applies a six-color poster effect and redisplays the image.

   LEADRasterProcess* pRasterProc= NULL;

     CoCreateInstance(CLSID_LEADRasterProcess, NULL, CLSCTX_ALL, IID_ILEADRasterProcess, (void**)&pRasterProc);
   pRasterProc->Posterize (LEADRasterView1->Raster, 6);
   LEADRasterView1->ForceRepaint ();
   pRasterProc-> Release( );
