LVectorWindow::ScaleIn

Summary

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

Syntax

L_VOID LVectorWindow::ScaleIn(L_VOID)

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;
