LVectorWindow::GetScaleFactor

#include "ltwrappr.h"

VECTORPOINT LVectorWindow::GetScaleFactor(L_VOID)

Gets the current scale factor for the LVectorWindow object.

Returns

A VECTORPOINT structure that holds the current LVectorWindow scale factor.

Comments

The LVectorWindow::ScaleIn and LVectorWindow::ScaleOut member functions use the scale factor to scale the currently loaded vector.

Scaling changes the internally stored scale of the vector.

   L_TCHAR     szTemp[100]; 
   //Get the current scale factor 
   scale = pVectorWindow->GetScaleFactor(); 
   wsprintf(szTemp, TEXT("ScaleFactor[%lf, %lf, %lf]"), scale.x, scale.y, scale.z); 
   MessageBox(NULL, szTemp, TEXT(""), MB_OK);
