Hi,
I am setting custom properties in a pdf which works fine.
I then take that file and lock it with an owner password to allow printing only.
After the file is locked the custom properties are no longer in the file.
If I remove the owner password they are gone as well.
I'm using the following permissions to secure the file:
Spire.Pdf.Security.PdfPermissionsFlags.Print | Spire.Pdf.Security.PdfPermissionsFlags.FullQualityPrint;
Is there something I'm missing to keep the custom properties?
Thanks
