org.faceless.pdf2.PDFAction
An action tells the PDF viewer how to navigate around the document.
Actions are performed when the user clicks on a PDFBookmark
,
when a Form
element or one of it's WidgetAnnotation
children
specifies an event, or optionally when an event occurs on a PDF
or PDFPage
, such as when the document is opened, printed or a page
is opened or closed.
The PDFAction
class has no public constructor, just a number of
static methods returning a new action of the specified type.

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.zoom
- The zoom level. A value of 0 or Float.NaN
leaves the zoom unchanged, 1 sets the zoom to 100%, 2 to 200% and so on.public static PDFAction goToFit(PDFPage page)

, the annotation rectangle is treated
as a Server-Side ImageMap. So for example, if the user clicks 20 points
from the left and 30 points from the top of the link rectangle, the
URL that is loaded is http://www.url.com/?20,30
.
public static PDFAction playSound(PDFSound s)
PDFSound
when activated.
This simpler of the two playSound methods plays the sound once at full
volume and with mixing turned off. See the PDFSound
class
for more information on limitations with sound in PDF documents.

PDFSound
when activated.
sound
- the PDFSound

- the volume of the sound, from 0 (off) to 100 (maximum)repeat
- whether to play the sound continuously or just oncemix
- whether to mix the sound in with any other playing samples, or replace thempublic static PDFAction named(String name)
Return a new PDFAction which runs the named action. Named actions are PDF viewer dependent, so should be used with care. The following actions are among those known to work in Acrobat 3 and 4 readers, and loosely correspond to the equivalent actions available from the menus in Acrobat.
public static PDFAction showWidget(WidgetAnnotation annot)
WidgetAnnotation
visible on screen.
annot
- the annotation to modifyhideWidget(org.faceless.pdf2.WidgetAnnotation)
public static PDFAction hideWidget(WidgetAnnotation annot)

public static PDFAction formSubmit(String url, int method)

event for a FormButton
somewhere in the form, so the form can be submitted.
The method parameter can be one of the various METHOD
values, although please note that many of these values are only implemented in
Acrobat 5.0 or later.
url
- the URL to submit the form tomethod
- the method to use when submitting the formForm
public static PDFAction formReset()
PDFAction
which resets the documents AcroForm,
setting every field to its default values.
Form
public static PDFAction formImportData(String file)
PDFAction
which imports a Forms Data Format (FDF)
file into the document AcroForm, setting some or all of the forms values.
file
- the name of the file containing the FDF. The file is relative to
the location of the current documentForm
public static PDFAction formJavaScript(String javascript)
Return a new PDFAction
which executes a JavaScript action.
This is generally used with AcroForms, although in theory it doesn't
have to be. It's generally better design to create functions in the
document-wide JavaScript (as set by PDF.setJavaScript(java.lang.String)
) and just
use these actions to call those methods.
javascript
- the JavaScript action to performPDF.setJavaScript(java.lang.String)
,
PDF.getJavaScript()
,
Form
public void setNext(PDFAction action)
setNext
method allows you to create "chains" of actions
which are executed whenever the first entry in the chain is run. This
allows more complicated processing - for example, clicking on a button
could play a sound and then jump to a specific page.
Avoiding infinite action loops is the responsibility of the programmer.
action
- the action to execute after the current one, or
null
to clear it.public PDFAction getNext()
null
if no further actions are defined.
public String getType()
Return the type of action. Can be "Named:value" (where "value" is the named action that's performed), "URL", "Sound", "GoTo", "GoToFitRectangle", "GoToFit", "GoToFitHeight", "GoToFitWidth", "ShowWidget", "HideWidget", "FormReset", "FormImportData", "FormSubmit", "FormJavaScript" or one of another type of action supported by the PDF specification but not by this library ("Launch", "Thread" or "Movie").
Note since 1.1.23 the URL value no longer includes the URL being referenced - use
the getURL()
method to retrieve that value
public PDFPage getPage()
public PDFSound getSound()
public WidgetAnnotation getAnnotation()
hideWidget(org.faceless.pdf2.WidgetAnnotation)
and showWidget(org.faceless.pdf2.WidgetAnnotation)
actions,
return the annotation being toggled shown or hidden.
public String getJavaScript()
JavaScript
type annotations, return the JavaScript
that is being executed. For other annotations, return null
.
public String getURL()
null
public int getFormSubmitMethod()
METHOD
parameters
defined in this class. For other action types the return is -1
formSubmit
actionpublic 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
.
