Recognition of check marks, signature validation, region extraction and other optical mark recognition functions.
Autonumber Increment Value
If you want to change the value of how much the Autonumber Increments each time from 1 to any number that you want then do the following:
1. Right click on the configuration file and “Open With” any text editor, such as Notepad.
2. Search for the following:
3. Change the number in this entry to the amount that you want the Autonumber to Increment:
4. Save the configuration file.
How do you configure OMR fields for check box recognition?
SimpleIndex supports simple checkbox recognition function that will give a field the value “1” when the amount of black pixels exceeds the specified threshold for that zone and “0” if not.
To configure a field for Optical Mark Recognition, select “OMR” for the field type on the Index options tab. In the Zones & OCR settings, click “Set Field Coordinates” and follow the on-screen instructions to mark the check box region on the image as you would with an OCR field. Use unchecked checkboxes for your sample image.
After drawing the zone and selecting the OMR field from the list, you will be prompted to enter a pixel threshold for the field. The number shown is the current number of black pixels in the selected zone. If the box is unchecked, the threshold should be slightly higher (10-20%).
If you enter a negative number for the threshold, images that exceed the threshold will have the OMR zone saved to a separate file. This is useful for signature capture and similar applications.
