Tip: Requesting all possible values for a scan parameter
If a scanner is configured to work with Imagenation, then you can use the scanning functions to set scan parameters, and to start and stop scanning.
Each supported scanner has two Imagenation dialog boxes associated with it: Scan Options, and Scan. The Scan Options dialog box contains options that are not often changed once set, and it should not be open when you are setting the parameters that it controls.
The Scan dialog box, on the other hand, contains settings that could change with every document scanned. If it is not open when you issue any scanning calls, Imagenation will open it.
To set scanning parameters:
· Use the IN_SetScanParameter function. For parameters and their values, see Scanning Parameters.
You can also request a scan parameter by using the IN_GetScanParameter function.
Tip: Requesting all possible values for a scan parameter
To begin scanning with the defined parameters:
· Use the IN_StartScan function.
The Scan dialog box opens, and scanning begins. Some parameters can be changed during scanning. For details on which ones, in Imagenation, press F1 when a scan dialog box is displayed.
When a scan is started, Imagenation sends a NotifyScanStart notification to clients, if registered to do so.
When a scan is finished, Imagenation sends a NotifyScanComplete notification to clients, if registered.
To cancel a scan:
· Use the IN_StopScan function.
The scan is canceled.
You can also control how settings are displayed in the Scan dialog box in the user interface. For details, click Customizing the Scan dialog box.
Note: Scanning is not supported in Imagenation for UNIX.
