When merging, a form's fields can be completed, the form flattened, form fields removed, existing values from a form field read, and the locations of form fields determined. When merging PDFs, there are also options for modifying pre-existing AcroForms. These topics are covered in the following documentation pages.
|Form Filling||Discusses merging form field values, using AcroForm field values, reorganized AcroForm fields, and FDF files.|
|Form Flattening||Discussed using flattening a form - remove all form field structures from the document and replacing them with their values.|
|Removing Form Fields||Discusses removing form fields from a PDF.|
|Reading Form Fields Values||Shows how to read the values of AcroForm fields from an existing PDF using the Form property of the MergeDocumnt class.|
|Retrieving Form Field Locations||Discusses retrieving the X and Y coordinates of a form field.|
|Marking Form Fields as Read Only||Shows how to mark form fields as read only so they cannot be modified once set.|
These topics discuss working with a pre-existing form. Refer to the Interactive Forms topic for documentation on creating a form.
