Declarationproperty LogFile: string;
LogFile specifies the file name that will contain the log of the communication between ImageEn and the scanner driver.
Set this property before use scanner related methods or properties.
Note: If multiple applications write simultaneously to the same log file you will encounter I/O errors. Ensure the log file is unique to your application (and each instance of your application if multiple instances may run concurrently).
