Function Documentation

void CWO::Resize	(	int	dNx,
		int	dNy,
		int	flag = CWO_INTER_LINEAR
	)

resize an image

   @param dNx new size along to horizontal direction 
   @param dNy new size along to vertical direction 
   @param flag interpolaion method (CWO_INTER_NEAREST, CWO_INTER_LINEAR, CWO_INTER_CUBIC,CWO_INTER_LANCSOZ)
   @note
   GetNx() and GetNy() returns new image sizes.    

        CWO a;
        a.Load("test.bmp");
        a.Resize(a.GetNx()*1.5,a.GetNy()*1.2,CWO_INTER_LINEAR); // the image is resized by horizontally 1.5 times and vertically 1.2 times, respectively
