ABBYY FlexiLayout Studio offers a visual editor to make specifying fuzzy intervals easier. You can open the fuzzy interval editor in one of two ways:
  • From the Properties dialog box of a Character String element: on the Character String tab, click the Browse button button.
  • From the main menu, select Tools → Fuzzy Interval Editor….

​
Graph axes and coordinates

The Fuzzy Interval Editor displays a graph representation of the fuzzy interval. The vertical axis measures the quality of the hypothesis, and the horizontal axis measures the linear dimensions or the number of characters. The graph also shows the coordinates where the fuzzy interval borders intersect the horizontal axis.

​
Zoom and pan the graph

The Zoom in and Zoom out buttons change the horizontal and vertical scales synchronously. You can also zoom a selected image area with the Zoom selected area button. The Move right button Move left button Move up button Move down button buttons move the area in the corresponding direction. To fit the interval, click Fit interval button.

​
Specify the interval

The fields under the graph contain the numerical values of the interval. You can specify the interval either by editing the graph with your mouse or by entering the numerical values in the corresponding fields. The visual fuzzy interval editor operates in two modes:
  • Distance – Fuzzy intervals for units of measurement, which may be fractional. Select Distance under Interval type.
  • Integer – Fuzzy intervals for positive integers, such as string length in characters. Select Integer under Interval type.
If you open the fuzzy interval editor from the Properties dialog box of a Character String element, one of the two modes is automatically selected depending on the field from which you called the editor.

​
Edit the graph

You can change the interval by moving the green markers to the right or to the left with your mouse. You can also change the angle of the slopes. Some restrictions apply. For example, you cannot move the left marker to the right of the right marker. The corresponding numerical values appear in the fields under the graph.

​
Change the numerical values directly

The fields correspond to the representation of the fuzzy interval in the program: Changing a slope moves the corresponding extreme point without changing the non-penalized point, and changing an extreme point or a non-penalized point changes the corresponding slope. When you edit any field, the graph and the values of the dependent fields update accordingly.

​
Save the results

If the fuzzy interval editor was called from the Properties dialog box of a Character String element, clicking OK automatically inserts the fuzzy interval into the corresponding field of the dialog box. If the fuzzy interval editor was called from the Tools menu, you can copy the fuzzy interval from the Result field or from the Code field. The Code field lets you paste the code onto the Advanced tab, for example, when using a fuzzy interval as an argument of the FuzzyQuality function.
