Description
Closes the specified image and frees up associated resources.
Syntax
| Visual Basic |

Public Sub CloseImage( _ ByVal lImageID As Long _ ) |
Parameters
- lImageID
- Which image buffer to close.
Remarks
When processing multiple buffers, you must track them and close those buffers with which you are finished. The control will be blank.
If any control references an image buffer (either in ProcessImageID or ViewImageID properties), the control is not freed, but it does blank out.
Example
Using CloseImage to handle multiple image buffers.
