Artículo

Gets the bounding rectangle of the selection after the SelectionResizing event, as a Rectangle structure.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in microsoft.ink.dll)

Syntax

'Declaration
Public ReadOnly Property NewPixelRect As Rectangle
'Usage
Dim instance As InkOverlaySelectionResizingEventArgs
Dim value As Rectangle

value = instance.NewPixelRect

public Rectangle NewPixelRect { get; }

public:
property Rectangle NewPixelRect {
    Rectangle get ();
}

/** @property */
public Rectangle get_NewPixelRect ()

public function get NewPixelRect () : Rectangle

Not applicable.

Property Value

The size of the selection after the SelectionResizing event.

Remarks

The NewPixelRect property provides specific information about the InkOverlaySelectionResizingEventArgs event.

Note

This Rectangle structure is specified in client window coordinates, which allows for scenarios such as maintaining the aspect ratio when resizing.

Example

This C# example creates an event handler, theInkOverlay_SelectionResizing, that affects a selected Strokes collection of an InkOverlay, theInkOverlay. If the selection is resized so that any of it extends beyond the boundaries of the control, the event handler turns the selection red. (Note that the handler sets the Color property to red for each Stroke in the Strokes collection, so it will be red even if the strokes are resized back within the boundaries.)

using Microsoft.Ink;
//...
  theInkOverlay.SelectionResizing += new InkOverlaySelectionResizingEventHandler(theInkOverlay_SelectionResizing);
//...
  private void theInkOverlay_SelectionResizing(object sender, InkOverlaySelectionResizingEventArgs e)
  {
      //Check the bounds of the resizing selection to see if it goes outside.
      if (e.NewPixelRect.Left < 0 || e.NewPixelRect.Right > ClientRectangle.Width ||
          e.NewPixelRect.Top < 0 || e.NewPixelRect.Bottom > ClientRectangle.Height)
      {
          //If too big change the color of the strokes to red.
          foreach (Stroke stroke in theInkOverlay.Selection)
          {
              stroke.DrawingAttributes.Color = Color.Red;
          }
     }

  }
//...
