The values of Acro Form fields can be read from an existing PDF document using the getForm() property of the MergeDocument class. In addition to being to read out the actual text values of the Form Fields, formatting of that Form Field (including font, font size, font color, background color, border color and border style) can also be retrieved.

This example shows how to read the value of Acro Form fields from an existing PDF document:

[Java]
    // Create a PdfDocument object
    MergeDocument mergeDocument = new MergeDocument("[PhysicalPath]/DocumentA.pdf");
    // Set the Acro Form field values to local variables
    String textBox1Value = mergeDocument.getForm().getFields().getPdfFormField("TextBox1").getValue();
    String checkBox1Value = mergeDocument.getForm().getFields().getPdfFormField("CheckBox1").getValue();
    String comboBox1Value = mergeDocument.getForm().getFields().getPdfFormField("ComboBox1").getValue();
    String radioButton1Value = mergeDocument.getForm().getFields().getPdfFormField("RadioButton1").getValue();
    String listBox1Value = mergeDocument.getForm().getFields().getPdfFormField("ListBox1").getValue();
