GraphicMode.SignNameOnly cut off to half Bounds

[Kevin.Cox]

Trying to add Name only as signature but the text gets cut off to half the width Bounds.
I assume this is normally to allow details to go next to the Name but in this case it's SignNameOnly.

Dim signature As New PdfSignature(doc, page, cert, userDesc)
signature.GraphicsMode = GraphicMode.SignNameOnly
signature.Bounds = New RectangleF(point, New SizeF(120, 30))

Hi,

Thank you for your inquiry.
I tested the code you provided and encountered the same problem as you.
As you guessed, GraphicMode. SignNameOnly cut off to half Bounds
The GraphicMode. SignNameAndSignDetail method will match the entire text box.
These are my test screenshots:

GraphicMode. SignNameAndSignDetail：

Thanks for your reply.
I only want the Name visible on the PDF.
Am I incorrect in assuming that SignNameAndSignDetail will add the certificate details?

Hi,

Thank you for your more inquiry
For your issue of “ SignNameAndSignDetail will add certificate details”?
Yes.If you only want to display the name in the PDF,you still choose SignNameOnly .

Issue is that SignNameOnly is cropped.
The width could be doubled to allow the full name but that looks very unprofessional and may also overlap another signature.
When I try to use Name only in another program like PDF XChange it allows full width for the name.

Hi,

Thank you for your more inquiry.
Our products follow the rules of Adobe software. When we manually add a signature with only signName in Adobe software, your signature will also be truncated to half the width Bounds. Therefore, this is a normal phenomenon.

Text to fills the frame but the bottom is clipped because the text is not centred vertically.

signature.Bounds = New RectangleF(point, New SizeF(120, 30))
signature.SignDetailsFont = New PdfTrueTypeFont(New System.Drawing.Font("Arial Unicode MS", 26.0F, System.Drawing.FontStyle.Regular))

Hi

Thank you for your feedback.
Since the PDF content is drawn on the page canvas, if your fixed the rectangle box size and the font size is too large, the content may not be able to fit completely within the box. To avoid this issue, you can reduce the font size appropriately.
Below is the sample code for your reference：

Code: Select all

Dim doc As New PdfDocument()
doc.LoadFromFile("ABC123-01-DW-0000-QC-CON-0003.pdf")
Dim cert As New PdfCertificate("test.pfx", "key")
Dim signature As New PdfSignature(doc, doc.Pages(0), cert, "signature")
signature.Bounds = New RectangleF(New PointF(-595, 421), New SizeF(120, 30))
Dim recWidth As Single = signature.Bounds.Width
signature.SignTextAlignment = SignTextAlignment.Center
      Dim text As String = "Kevin.Cox"
      signature.Name = text
      Dim fontsize As Single = 26.0F
      Do While fontsize > 0F
         Dim f1 As New Font("Arial Unicode MS", fontsize, FontStyle.Regular)
         Dim font As New PdfTrueTypeFont(f1, fontsize)
         Dim fontWidth As Single = font.MeasureString(text).Width

         If recWidth / 4 > fontWidth Then
            signature.SignDetailsFont = font
            Exit Do
         Else
            fontsize -= 1
         End If
      Loop
      signature.DocumentPermissions = PdfCertificationFlags.AllowFormFill Or PdfCertificationFlags.ForbidChanges
      signature.GraphicsMode = GraphicMode.SignNameOnly
doc.SaveToFile("out.pdf")
