Summary

Gets the current scale factor for the LVectorWindow object.

Syntax

#include "ltwrappr.h"

VECTORPOINT LVectorWindow::GetScaleFactor(L_VOID)

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_INT LVectorWindow__GetScaleFactorExample(LVectorWindow *pVectorWindow) 
{ 
   VECTORPOINT scale; 
   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); 
 
   return SUCCESS;
