BinaryFilter example for C++ Builder

This example does omni-directional erosion of black objects and repaints the image.

   LEADRasterProcess* pRasterProc= NULL;

     CoCreateInstance(CLSID_LEADRasterProcess, NULL, CLSCTX_ALL, IID_ILEADRasterProcess, (void**)&pRasterProc);
   LEADRasterView1->Raster->UnlockSupport (L_SUPPORT_DOCUMENT, AnsiToOLESTR("TestKey"));
   pRasterProc->BinaryFilter (LEADRasterView1->Raster, BFLT_EROSION_OMNI);
   LEADRasterView1->ForceRepaint ();
   pRasterProc-> Release ( );
