I want to create a locked document created by XeLaTeX
, using \special
command. The instructions are provided here. By setting perm
as 0x0904 the document can be signed in Acrobat (If there has been a signature region before).
I have found that digsig
package and eforms
package can help me to produce a signature region by loading pdfLaTeX
. The instructions can be refered here. However, both of them do not work in XeLaTeX
, which confuses me a lot (Because I have to create a document by XeLaTeX
). I wonder if there is a method to make them effective in XeLaTeX
? If not, is there a better package to support the digital signature?
Best Answer
Inserting the following code somewhere would work
This is XeLaTeX version of what digsig.sty actually does.
