LVectorWindow::ScaleOut

#include "ltwrappr.h"

L_VOID LVectorWindow::ScaleOut(L_VOID)

Reduces the scale of the displayed vector by the scale factor that is set by LVectorWindow::SetScaleFactor.

Returns

None.

Comments

This will modify the scale by dividing by the amount specified in LVectorWindow::SetScaleFactor. Scaling changes the internally stored scale of the vector. Zooming does NOT change a vector in any way. Scaling should be used instead of zooming when the user wants to select one or more objects in a vector, and enlarge or shrink only the selected objects, leaving the non-selected objects unchanged.

Example

Assumes pVectorWindow points to a valid LVectorWindow object.

L_INT LVectorWindow__ScaleOutExample(LVectorWindow *pVectorWindow)
{
   //Set the scale factor, and then scaleIn
   VECTORPOINT scalePoint = {1.2F, 1.2F, 1.2F, 0};
   pVectorWindow->SetScaleFactor(&scalePoint);
   pVectorWindow->ScaleOut();
   return SUCCESS;
