Return value
Number of the action
Remarks
This method creates an action that allows users to load data into a predefined form in a PDF document from an external FDF file. The method creates a JavaScript action. The structure of an FDF file can be found in the Adobe PDF Reference (8.6.6 Forms Data Format).
The return value is an action identifier in the document's actions collection and can be used in OnOpenDocument, OnControlMouseDown and other OnAnnot* properties (see Annotations).
The following example demonstrates form data importing. Click here to download the FDF file used. (It is ZIP archive containing the "import.fdf" file). You may unpack it for viewing with any text editor.
