Importing Data into PDF Forms

PDF Forms Flattener can help you import data into blank PDF forms and save the documents as completed forms. You can then flatten the forms for final use. Here’s how it works for different types of PDF forms:

•  AcroForms: Import data using FDF, XFDF, or XML files. These formats provide a flexible way to populate fields in AcroForms documents.
•  XFA Forms: Use XFD, XDP, or XML files to populate fields in XFA forms documents. These formats cater specifically to the dynamic nature of XFA forms.

By supporting both AcroForms and XFA forms, Forms Flattener is very versatile in handling various document types.

Exporting Data from PDF Forms

Not only can PDF Forms Flattener import data, but it can also export it. This feature works seamlessly for both AcroForms and XFA forms:

•  AcroForms: Export data in FDF, XFDF, or XML formats.
•  XFA Forms: Export data using XFD, XDP, or XML formats.

This bidirectional data capability makes Forms Flattener an indispensable tool for workflows that require dynamic form management.

Generating Annotation Appearances

Annotations in a PDF document often include optional entries that dictate their appearance in a viewer. For instance, a hyperlink might appear as blue text on a page. However, in many cases, these appearances are not predefined in the PDF. When you open such a PDF in Adobe Acrobat, the software generates the annotation appearances dynamically. If you save the document afterward, these appearances become part of the updated PDF.

PDF Forms Flattener streamlines this process by programmatically generating missing annotation appearances. Here’s how it works:

• Automatic Appearance Generation: Forms Flattener processes standard PDF documents (or sets of documents) to generate missing annotation appearances.
• Non-Form PDFs: If the input file is not a form, Forms Flattener will simply generate the annotation appearances without flattening or altering the document.

Processing Input Documents

Forms Flattener determines the type of input document before performing any operations, ensuring accurate processing:

•  Non-Form PDFs: Missing annotation appearances are generated, but no further changes are made.
•  AcroForms: Missing annotation appearances are generated, and the document is flattened during the output process.
•  XFA Forms: The document is read, flattened, and saved as an output PDF file, ensuring a complete and finalized document.
