To specify the right boundary of the search area of the DeliveryAddress element, describe the corresponding vertical white gap.

​
Create the wgAddressRight element

1

Create the White Gap element

In the InvoiceHeader.grAddress element, create a White Gap element and name it wgAddressRight.
2

Set the orientation and width

Click the White Gap tab. In the Orientation group, select Vertical. Set Min width to 100.
Before setting the height or width of a white gap, analyze the geometrical properties (size and boundaries) of the neighboring objects detected during pre-recognition. Values for the noise threshold in the white gap area are selected by trial and error.
3

Set the noise thresholds

Set Lower threshold limit and Threshold coefficient (%) to 10. Leave the default values for the element’s other parameters.
The values of Lower threshold limit, Upper threshold limit, and Threshold coefficient (%) are selected by trial and error. For more information, see White Gap.

4

Set the location relation

Click the Relations tab. The sought white gap can be located only to the right of the kwDeliveryAddress name keywords, so set this relation:
  • Right of the kwDeliveryAddress element, Offset = 0
5

Add the search constraints

Click the Advanced tab. The Delivery Address field is optional, but whenever it occurs it has a name, so look for the white gap only if kwDeliveryAddress was detected. The white gap is also adjacent to the Invoice Number field, so look for the object nearest to kwInvoiceNumber. In the Advanced pre-search relations field, set these additional search constraints. In the FlexiLayout language:
You can also set the Nearest constraint via the FlexiLayout Studio graphical user interface. Click the Relations tab, select Nearest, and in the To drop-down list select Element, and then specify kwInvoiceNumber as the Reference element.

Verify the match

Match the FlexiLayout with the test images and confirm that FlexiLayout Studio detects the element on all the images where the Delivery Address field occurs.
