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.
