DIGITAL INK
Digital ink controls provide support for stylus input from tablet PCs (where you use a plastic stylus similar to a pen to draw right on a tablet PC’s touch screen). Normally you would only use digital ink in a tablet PC application where the user is expected to enter data by drawing on the screen with a stylus. These applications usually provide text recognition to understand what the user is writing. They also use the stylus to perform the same operations they would perform with the mouse on a desktop system. For example, they let you tap to click buttons, and tap and drag to move items.
Although ink controls are most useful for tablet PCs, WPF includes two ink controls that you can use in any Visual Basic application.
| CONTROL | PURPOSE |
| InkCanvas | Displays or captures ink strokes. |
| InkPresenter | Displays ink strokes. |
