Initialize the driver iteration cycle to obtain scanner information from a ISISSELECTION structure.

Declaration:

AT_ERRCOUNT ACCUAPI IG_ISIS_selection_iterate_init(
        LPHISISSEL lphSelection,
        LPHISISSELITER lphIteration,
        LPAT_ISIS_DRIVERINFO lpDriverInfo
);

Arguments:

Return Value:

Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

Supported Raster Image Formats:

This function does not process image pixels.

Remarks:

The IG_ISIS_selection_iterate_init function starts the iteration cycle and fills in the first scanner information record.

The IG_ISIS_selection_iterate_init and IG_ISIS_selection_iterate_next functions go through the drivers in the mySelection list to obtain information on all scanner models supported by those drivers. Each AT_ISIS_DRIVERINFO structure returned in driverInfo contains the model name of the scanner, its associated driver, and a unique ID. Your application can then present a list of all the supported scanner models to the user. If you keep track of the association between the scanner name and its ID, you can then use the IG_ISIS_selection_get_driver_info function to retrieve the scanner information record after the user selects a scanner.

You should call IG_ISIS_selection_iterate_next repeatedly until all the records have been found. Then call IG_ISIS_selection_iterate_done to release the memory allocated for the iteration cycle.
