Set PDF Information

One other great feature of PDF documents is the possibility of setting metainformation such as Subject, Keyword, Author. Such metainfomation could then read by the document management system to index the documents.

Please see the VBS code below to learn how to use this API.

dim pdf
set pdf = createobject("aloahapdf.edit")
if pdf.load_pdf_to_mem(cstr("c:\document.pdf")) = true then
     if pdf.set_PDFInformation(clng(PDF_InfoType), cstr(PDF_InfoValue)) = true then
          call pdf.save_pdf_to_file(cstr("c:\newdocument.pdf"))
     end if
end if
set pdf = nothing

The Variable PDF_InfoType can have the following values:

1 = Author
2 = Title
3 = Subject
4 = Keywords
