Analyze and activate empty forms

The current empty form recognition core is mainly based on the LFR technology which was the backbone of OmniForm, and is now an integrated part of the CSDK. LFR recognizes textual and non-textual elements in empty forms, for example check boxes, circle texts, comb fields, tables and cells, graphics, lines, and boxes. These detected form field zones cannot be modified programmatically, but the page can be viewed and modified in the TEC.

The aim of this module is to turn a form image into a fillable electronic form that can be distributed to respondents or posted on a website. The data in the returned forms can then be processed by any suitable means, outside the scope of the CSDK. The filled form data is returned electronically, so there is no need to use anchor zones.

  1. Load a single-page image of a form.
  2. Specify user zones manually.

    • Define the whole page as a single form.

    • Define one or more separate form type user zones.

  3. Perform page decomposition.

    LFR runs inside the defined form zones, as part of the Zone handling module. It auto-detects form elements and creates active form controls.

  4. Inspect the auto-detected form objects in the TEC visual control.

    It is possible to move, resize or delete auto-detected objects, and add new objects. TEC also lets you view and modify form object attributes.

  5. Save the results to a format that supports active form elements: formatted XML, RTF (Microsoft Word) and PDF, optionally with Acro-Form-like fillable field definitions.

    Form object attributes can also be modified in the target application.
