Yes, Docparser allows you to detect the value of boolean form elements, such as checkboxes and radio buttons.
You can select our "Checkbox" or "Radio Button" preset and the draw a crop area around the position where the form element is located inside your PDF or scanned document. Docparser will then attempt to identify the form element in the selected area and return a boolean value (0/1, yes/no, true/false). Please note that currently only one form element can be detected for each area selection.
