SetSrcRect example for C++ Builder

This example zooms in on the image by reducing the source rectangle and repaints the image.

   float NewLeft, NewTop, NewWidth, NewHeight;

   NewLeft= LEADRasterView1->SrcLeft + (LEADRasterView1->SrcWidth * 0.1);
   NewTop= LEADRasterView1->SrcTop + (LEADRasterView1->SrcHeight * 0.1);
   NewWidth = LEADRasterView1->SrcWidth * 0.8;
   NewHeight = LEADRasterView1->SrcHeight* 0.8;
   if ((NewWidth > 1) && (NewHeight >1))
      LEADRasterView1->SetSrcRect (NewLeft, NewTop, NewWidth, NewHeight);
   LEADRasterView1->ForceRepaint ();
