How to automate a Polygon Annotation creation?

Hi,

I have question regarding the creation of a new annotation type as "Polygon" through Access VBA.

The "vertices" is defined as an array of array in the Acrobat Javascript API, but it is suggested the refer to the PDF Reference.

In the PDF Reference 1.7 I found nothing more anyway

Vertices - array - (Required) An array of numbers representing the alternating horizontal and vertical coordinates, respectively, of each vertex, in default user space.

So I tried to implement the following procedure:

Sub CreateNewAnnotationPolygon()

Dim AcrApp As Acrobat.Acroapp 'Application Acrobat

Dim AcrAvDoc As Acrobat.AcroAVDoc 'Document actif dans Acrobat

Dim pdDoc As Acrobat.CAcroPDDoc

Dim page As Acrobat.CAcroPDPage

Dim Jso As Object

Dim path As String

Dim popupRect(3) As Integer

Dim Rect(3) As Integer

Dim PolVertices(1, 3) As Variant ' only four vertices are needed

Dim pageRect As Object

Dim Annot As Object

Dim Props As Object

Dim Color(0 To 3) As Variant

Set AcrApp = New Acrobat.Acroapp

Set AcrAvDoc = AcrApp.GetActiveDoc

Set pdDoc = AcrAvDoc.GetPDDoc

Set Jso = pdDoc.GetJSObject

If Not Jso Is Nothing Then

    ' Get size for page 0 and set up arrays

    Set page = pdDoc.AcquirePage(0)

    Set pageRect = page.GetSize

    Rect(0) = 20                     ' to define the position of the annotation

    Rect(1) = pageRect.y - 10

    Rect(2) = 20             ' actually I doubt if it is correct to define also rect(2) and rect(3)

    Rect(3) = pageRect.y    

    PolVertices(0, 0) = 0

    PolVertices(1, 0) = 10

    PolVertices(0, 1) = 0

    PolVertices(1, 1) = 0

    PolVertices(0, 2) = 20

    PolVertices(1, 2) = 10

    PolVertices(0, 3) = 20

    PolVertices(1, 3) = 0

    ' Create a new Polygon annot

    Set Annot = Jso.AddAnnot

    Set Props = Annot.getprops

    Props.Type = "Polygon"

    Props.bordereffectIntensity = 1

    Props.Width = 1

    Annot.setProps Props

    ' Fill in a few fields

    Set Props = Annot.getprops

    Props.page = 0

    Props.Rect = Rect

    Props.Vertices = PolVertices ' HERE THE PROCEDURE STOPS WITH THE ERROR "Property not supported by the object"

    Props.Author = "Michele"

    Props.Subject = "Example Polygon shape"

    Color(0) = "RGB"

    Color(1) = 1#

    Color(2) = 0#

    Color(3) = 0#

    Props.StrokeColor = Color

    Annot.setProps Props

    pdDoc.Close

    'MsgBox "Annotation added"

Else

    MsgBox "Failed to open"

End If

Set Annot = Nothing

Set Props = Nothing

Set page = Nothing

Set pageRect = Nothing

Set Jso = Nothing

Set pdDoc = Nothing

Set AcrAvDoc = Nothing

Set AcrApp = Nothing

End Sub

Can you suggest where is the error?

Thanks in advance,

Michele.
