How would one get the position and size of a PdfField to place an image over this field? I'm attempting to place a signature gif on top of a PdfField.

Dim doc As New PdfDocument(pdfFileName)

'Load the image
Dim image As System.Drawing.Image = System.Drawing.Image.FromFile("c:\signature.gif")

'Create a new PdfImage object
Dim pdfImage As New EO.Pdf.Drawing.PdfImage(image)

'Create a new PdfImageContent object
Dim content As New EO.Pdf.Contents.PdfImageContent(pdfImage)

'Get the signature field
Dim field As PdfField = doc.Fields("signature")

'Can set the field value
field.Value = "John Smith"

'but how do you get its position and size so one can place the signature image over this field?

'Move the image on top of the pdf form signature text field
content.GfxMatrix.Translate(?, ?)

'Scale the image (is this necessary?)
content.AutoScale()

'Get the first page
Dim FirstPage As PdfPage = doc.Pages(0)

'Place the image on the page
firstpage.Contents.Add(content)

'Save it to a new file
doc.Save(newFileName)
