| 2. | Add the LEAD RasterImageViewer Control to your project. |
| On the Project pull-down menu, use the Components option, and select the LTDWinFormsInterop.. | |
| 3. | Add the RasterCodecs to your project. |
| On the Project pull-down menu, use the References option, and select the LTDCodecsInterop. | |
