Signature Index Function
This function scans both symbol and signature at one time and outputs the symbol data and
indexed signature at the same time. The position and size of a signature can be specified in the
user application based on the position of the symbol.
The function automatically corrects the up and down positions of the captured symbol in
correspondence with the up and down positions of the image data even if it has been captured
upside down or diagonally, and then outputs it.
