Comments

Call L_CC_CreateScanner before calling any other LEADTOOLS Credit Cards toolkit functions.

When the handle to the Scanner session is no longer needed, free it by calling L_CC_DestroyScanner. For every call to L_CC_CreateScanner there must be a call to L_CC_DestroyScanner.

As many frames as needed for recognition can be added using this method. It will often take more than one frame to get accurate results. It is best to call this method repeatedly with a stream of images until accurate data has been acquired. If the Focus Score is above the MinimumFocusScore the frame will be added.

After this method returns, the frame data passed is no longer required and can be freed by the caller.

For a complete example, refer to the CreditCardCapture demo.
