LoadUseViewPerspective example for C++ Builder

This example times the loading of a bitmap with and without changing the internal view perspective.

   double StartTime, EndTime, DeltaTime;
   LEADRasterIO* pRasterIO= NULL;

     CoCreateInstance(CLSID_LEADRasterIO, NULL, CLSCTX_ALL, IID_ILEADRasterIO, (void**)&pRasterIO);

   //Do not include paints when measuring time.
   LEADRasterView1->AutoRepaint = False;
   //Time the load using the bitmap//s view perspective
   pRasterIO->LoadUseViewPerspective = True;
   StartTime= Time();
   pRasterIO->Load (LEADRasterView1->Raster, AnsiToOLESTR("v:\\images\\bird.tif"), 0, 0, 1);
   EndTime= Time();
   DeltaTime= EndTime - StartTime;
   ShowMessage(IntToStr((int)DeltaTime) + " seconds loaded as is");
   //Time the load that converts the bitmap//s view perspective
   pRasterIO->LoadUseViewPerspective= False;
   StartTime= Time();
   pRasterIO->Load (LEADRasterView1->Raster, AnsiToOLESTR("v:\\images\\bird.tif"), 0, 0, 1);
   EndTime= Time();
   DeltaTime= EndTime - StartTime;
   ShowMessage (IntToStr((int)DeltaTime) + " seconds converted on load");
   pRasterIO-> Release( );
