Occurs before selected strokes and elements are resized.

'Declaration
Public Event SelectionResizing As InkCanvasSelectionEditingEventHandler
'Usage
Dim instance As InkCanvas 
Dim handler As InkCanvasSelectionEditingEventHandler 

AddHandler instance.SelectionResizing, handler
<object SelectionResizing="InkCanvasSelectionEditingEventHandler" .../>

This event occurs after the user requests that a selection of strokes and/or elements be resized, but before the change is applied.

The event handler receives an argument of type InkCanvasSelectionEditingEventArgs that contains two properties: OldRectangle and NewRectangle. OldRectangle defines the boundaries of the selection before the resizing operation and NewRectangle defines the boundaries of the selection after the resizing operation.

After the strokes and/or elements are updated with the new size, the SelectionResized event is raised.

The following example prevents the user from making a selection smaller than its original size.

Private selectionBounds As Rect

' Don't allow the user to make the selection smaller than its original size. 
Private Sub inkCanvas1_SelectionResizing(ByVal sender As Object, ByVal e As InkCanvasSelectionEditingEventArgs)

    If selectionBounds.IsEmpty Then 
        Return 
    End If 

    Dim resizeHeight As Double 
    Dim resizeWidth As Double 

    ' If the user made the height of the selection smaller,  
    ' use the selection's original height. 
    If e.NewRectangle.Height < selectionBounds.Height Then
        resizeHeight = selectionBounds.Height
    Else
        resizeHeight = e.NewRectangle.Height
    End If 

    ' If the user made the width of the selection smaller,  
    ' use the selection's original width. 
    If e.NewRectangle.Width < selectionBounds.Width Then
        resizeWidth = selectionBounds.Width
    Else
        resizeWidth = e.NewRectangle.Width
    End If 

    ' Create a the new rectangle with the appropriate width and height.
    e.NewRectangle = New Rect(e.NewRectangle.X, e.NewRectangle.Y, resizeWidth, resizeHeight)

End Sub 'inkCanvas1_SelectionResizing


' Keep track of the selection bounds. 
Private Sub inkCanvas1_SelectionChanged(ByVal sender As Object, ByVal e As EventArgs)

    selectionBounds = inkCanvas1.GetSelectionBounds()

End Sub 'inkCanvas1_SelectionChanged
