LVectorWindow::ScaleIn

#include "ltwrappr.h"

L_VOID LVectorWindow::ScaleIn(L_VOID)

Increases 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 the multiplying by the factor 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__ScaleInExample(LVectorWindow *pVectorWindow)
{
   //Set the scale factor, and then scaleIn
   VECTORPOINT scalePoint = {1.0f, 1.1f, 1.2f, 0};
   pVectorWindow->SetScaleFactor(&scalePoint);
   pVectorWindow->ScaleIn();
   return SUCCESS;
