Problems with PushButtons and FormFieldFacade

Aspose.PDF Product Family

I’m attempting to add a “Print Certificate” push button on my PDF but I’ve run into a couple of problems:

1. When the AddField is done without decorating, the text is rotated at 90 by default
2. When I use a FormFieldFacade to decorate my PushButton field, the formatting works but the text of the button and it’s javascript commands are lost, rendering the button useless.

Here’s my code snippet:

Dim editorObject As New FormEditor(outputStream, outputStream2) 'memory streams, outputStream has the certificate file
editorObject.AddField(FieldType.PushButton, “btnPrint”, “Print Certificate”, 1, 775, 610, 625, 580)
editorObject.Save()
outputStream2.Seek(0, SeekOrigin.Begin)

editorObject = New FormEditor(outputStream2, outputStream)
editorObject.SetFieldScript(“btnPrint”, “this.print();”)
editorObject.SetFieldAppearance(“btnPrint”, AnnotationFlag.VisibleButNotPrint)
editorObject.Save()
outputStream.Seek(0, SeekOrigin.Begin)

’ *** if I return the contents of outputStream here, I get a valid pushbutton with rotated 90 text but good javascript
'Return outputStream.GetBuffer()

’ Decorate the button
editorObject = New FormEditor(outputStream, outputStream2)
Dim facade As FormFieldFacade = New FormFieldFacade()
facade.BackgroudColor = System.Drawing.Color.Yellow
facade.TextColor = System.Drawing.Color.Red
facade.Alignment = FormFieldFacade.AlignCenter
facade.Rotation = 0

editorObject.Facade = facade
editorObject.DecorateField(“btnPrint”)
editorObject.Save()
outputStream2.Seek(0, SeekOrigin.Begin)

Return outputStream2.GetBuffer() ’ this returns a formatted pushbutton with no text and no javascript, so I can’t even tell if the rotation was corrected, either.



Any ideas?

Hi Steve,

Thank you very much for considering Aspose.

We’re looking into the matter, however it’ll be helpful in investigating the problem that you share the PDF file you’re having problem with. You can attach the file with this forum.

We appreciate your patience and cooperation.

I’m fairly certain this behavior works with any PDF but I’m using the attached PDF in particular, as it’s the template PDF for creating certificates on our website. I’ve attached the PDF at the state where the form fields were filled and then flattened, so all I need to do is add a “Print Certificate” button in the upper right-hand corner.
