If specified, The opened page will be the one containing that element and the "page" parameter is ignored.

        Some examples: 

         "a.pdf"             // Link to file "a.pdf" embedded in this PDF
 "a.pdf/b.pdf"       // Link to file "b.pdf" embedded in "a.pdf", which is embedded in this PDF.
 "a.pdf/b.pdf#body"  // As above, but ignore "page" and jump to the page containing the element "body".
 ".."                // Link to the parent PDF that embeds this PDF.
 "../a.pdf"          // Link to the file "a.pdf" which is embdded as a sibling of this PDF.
        Parameters:
        path - the relative "path" to the file.
        page - the page number to open: 0 for the first page. Ignored if "path" contains a fragment
        x - the X position on the new page to scroll to, or Float.NaN to keep the X position unchanged.
        y - the Y position on the new page to scroll to, or Float.NaN to keep the Y position unchanged.

        Avoiding infinite action loops is the responsibility of the programmer.

        Parameters:
        action - the action to execute after the current one, or null to clear it.

      • getGoToCoordinates

        public float[] getGoToCoordinates()

        Return the co-ordinates of a GoTo action. Some "GoTo" actions take one or more coordinates which determine which section of the specified page should be displayed. Examples of this are the goToFitRectangle method, which takes four parameters, and the goToFitWidth method, which takes one. These coordinates can be read by calling this method, which returns an array of floats, the length of which varies depending on the type of GoTo action.

        Specifically, "GoToFitWidth" and "GoToFitHeight" methods return an array of one float, "GoToFitRectangle" will return four and "GoTo" will return three. For this last one, the first number represents the "X" coordinate, the second the "Y" and the third the zoom level, but it's important to remember that any one of these may be unspecified - in this case the value is set to Float.NaN.
