Sample 2. Step 13: Describe the field that contains the name of the recipe

Locate the recipe name field with a RecipeName Character String element, combining NearestY constraints with excluded regions to narrow the search area.

Describe the recipe name field as the object closest to the bottom boundary of the form’s heading, but exclude the regions that contain the Recipe and RecipeNumber elements. For more information, see Step 8.

This takes two tasks: create a RecipeName Character String element for the recipe name, and then create a RecipeName block for the field.

1. Create the Character String element

   Create a Character String element and name it RecipeName. It corresponds to the recipe name.

2. Open the Character String tab

   Click the Character String tab.

3. Set the alphabet

   Set the required alphabet. In the test images, it includes all the letters of the English alphabet, digits, and the characters #, -, &, and .. The order and number of characters are not known in advance.

4. Set the percentage of alphabet characters

   Set Percentage of alphabet characters to 1.

5. Disable embedded hypotheses

   Clear the Allow embedded hypotheses check box.

6. Set the percentage of non-alphabet characters

   Set Percentage of non-alphabet characters to 0.2 (that is, 20%).

7. Set the character count

   In the Character count field, specify the fuzzy range that estimates the total length of all the character strings. Keep the default range of {-1, -1, INF, INF}, which means there are no constraints on the length of the character string.

8. Set the vertical search constraint

   Click the Relations tab.

   Tell FlexiLayout Studio that the recipe name is at least 100 dots lower than the bottom boundary of the form’s heading. In other words, there must be a gap at least 100 dots wide between the heading and the recipe name.

   Every line below the heading meets this criterion, so the search area must be narrowed further.

9. Narrow the search to the closest line

   Click the Advanced tab.

   In the Advanced pre-search relations field, specify an additional search constraint: look for the line closest to the top boundary of the document. In the FlexiLayout language, write it as follows:

   NearestY: 0*dot;
   

   Together with the search constraint on the Relations tab, this narrows the search area to the one line closest to the document heading.

   You can also specify this constraint via the graphical user interface. Click the Relations tab, select Nearest, and in the To drop-down list select Page top edge.

   
10. Open the Search Constraints tab

    Click the Search Constraints tab.

11. Exclude the Recipe and RecipeNumber regions

    As stated in Step 8, exclude the regions of the Recipe and RecipeNumber elements from the search area for RecipeName.

    Click the Add… button next to the Exclude regions of elements field, and then in the Select Element to Exclude dialog box select the Recipe and RecipeNumber elements.

    

Match the FlexiLayout against the test images and confirm that FlexiLayout Studio finds the recipe name field on every image.

Create the RecipeName block

Create the RecipeName block the same way as the RecipeNumber block. The only difference is that you must specify the RecipeName element as the source element for the RecipeName block.
