Declarations
Declare Function DomPDFEncrypt Lib "DOMINOPDF.DLL" (Byval szInput As String, Byval szOwnerPass As String,_
Byval szUserPass As String, Byval iAllowPrint As Long, Byval iAllowCopy As Long,_
Byval iAllowChange As Long, Byval iAllowAnnotate As Long, Byval iAllowFields As Long,_
Byval iAllowCopyAccess As Long, Byval iAllowAssemble As Long, Byval iAllowPrintFull As Long,_
Byval iStrength As Long) As Long
Return Value
Returns 0 if successful or -1 if unsuccessful.
Syntax
szInput - The file name and path of the PDF file to be encrypted.
For example;
c:\contacts.pdf
c:\my documents\contacts.pdf
szOwnerPass - Specify the owner password to apply to PDF documents.
szUserPass - Specify the user password to apply to PDF documents.
iAllowPrint - Set this to 1 to allow the user to print the PDF document.
iAllowCopy - Set this to 1 to allow the user to copy text and graphics from the PDF document.
iAllowChange - Set this to 1 to allow the user to edit the PDF document.
iAllowAnnotate - Set this to 1 to allow the user to add annotations to the PDF document.
iAllowFields - Set this to 1 to allow the user to fill in form fields. Only works with 128-bit encryption strength (see iStrength).
iAllowCopyAccess - Set this to 1 to enable copying for use with accessibility features. Only works with 128-bit encryption (see iStrength).
iAllowAssemble - Set this to 1 to allow the user to assemble the PDF document. Only works with 128-bit encryption (see iStrength).
iAllowPrintFull - Set this to 0 to force low-resolution printing of the PDF document only. This prevents the document from being distilled into a new PDF document. Only works with 128-bit encryption (see iStrength).
iStrength - The strength of encryption to use: 0 = Standard 40-bit encryption. 1 = Advanced 128-bit encryption.
