Frames mark the individual check boxes. Inside the frame, box checking is examined. Only one type of frame is usually used in the template (if all check boxes are the same). However, it is possible to use multiple types of frames simultaneously.
After adding the frame definition, click theitem in the tool bar. Subsequently, select any frame that has been scanned in good quality and left-click in the center of it. After clicking, the frame will be measured and information that a frame has been found will be displayed. The parameters of the frame can be adjusted in the tool bar. They include determination of the limit indicating that the box has been checked. The limit is specified in percentage of filling of the inner area of the frame.
In evaluating the forms, for each box determination is made whether it is empty, checked or filled. In order to allow the person filling the form to perform corrections (accidentally checked box), a completely filled box will be regarded as empty i.e. unchecked. In the tool bar, it is possible to change the limits of filling for all these cases.
Empty - the box is evaluated as empty if its filling is smaller than the "Maximum Filling" value
Checked - the box is evaluated as checked if it is filled in the range from the "Minimum Filling" value to the "Maximum Filling" value
Filled - the box is evaluated as filled if its filling is smaller than the "Maximum Filling" value
If the value is outside all of the above-defined intervals, the given group of boxes will be subject to manual correction. Alternatively, depending on the selected strategy, the value of the entire group is determined automatically.
