Optimizes fonts used in the currently loaded PDF document in order to minimize its file size for archiving.
This method is useful primarily for PDF documents intended for storing or archiving to reduce its file size. The toolkit replaces the fully embedded fonts included in the document with their corresponding subsets and removes all other unnecessary data found in the existing font files as well. Be aware that subsequent editing of such optimized document may lead to insufficient rendering.
Syntax
Return Value
A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.
We strongly recommend always checking this status first.

Dim caption As String = "Example: PackFonts"
Using gdpicturePDF As GdPicturePDF = New GdPicturePDF()

If gdpicturePDF.PackFonts() = GdPictureStatus.OK Then
If gdpicturePDF.SaveToFile("test_optimized.pdf") = GdPictureStatus.OK Then
MessageBox.Show("The example has been followed successfully.", caption)
Else
