There are all three steps to create a PDF Form Field:
- New a object of Class FormEditor specifying the name of original PDF document and the result PDF document.
- Add a kind of field with FormEditor.AddField Method
- Use the FormEditor.Save Method to store all modifications.
// Open the document and create a Form object FormEditor formEditor = new FormEditor(In_Template + "FormEditor.blank.pdf", OutPath + "added.pdf"); // add a button field formEditor.addField(FormEditor.FLDTYP_BTNFLD, "button1", "ButtonName", 1, new Rectangle(50, 50, 100, 20)); // add a text field formEditor.addField(FormEditor.FLDTYP_TXTFLD, "text1", "TextName", 1, new Rectangle(200, 50, 100, 20)); // set items for a ComboBox formEditor.setItems(new String[] { "123", "abc", "456" }); // add a combo box field formEditor.addField(FormEditor.FLDTYP_COMBOBOX, "combobox1", "", 1, new Rectangle(50, 100, 100, 40)); // add a check box field formEditor.addField(FormEditor.FLDTYP_CHKBOX, "checkbox1", "", 1, new Rectangle(200, 100, 20, 20)); //set items for a list box formEditor.setItems(new String[] { "123", "abc", "456" }); // add a list field formEditor.addField(FormEditor.FLDTYP_LIST, "list1", "", 1, new Rectangle(50, 200, 100, 20)); // set items for a radio group formEditor.setItems(new String[] { "1", "2", "3" }); // add a radio button field formEditor.addField(FormEditor.FLDTYP_RADIOBTN, "radio1", "", 1, new Rectangle(200, 200, 20, 20)); // Close the document formEditor.close();
Decorate PDF Form Fields With API
When create PDF Form Fields, developers can decorate fields at the same time to get a better effect of vision. Aspose.Pdf.Kit provides Class FormFieldFacade to achieve this goal. The attributes of a field that can be decorated are border style, width / border color, background color / font, font size / caption / text color, text alignment, text rotation. To get detail informations, please read the FormFieldFacade Members.
To use Class FormFieldFacade, developers should cooperater with Class FormEditor keeping with the following steps:
- New a object of Class FormFieldFacade and Class FormEditor, specify the Property FormEditor.Facade to the new object of Class FormEditor.
- Decorate the attributes of PDF Form Fields with Class FormFieldFacade.
- Call FormEditor.ResetFacade to clear all visual attribtues to empty value after decorating all attributes.
- Use the FormEditor.Save Method to store all modifications.
