getPermissions
Get the permission word from an input PDF file.
getPermissions([in] LONG inputHandle, [out, retval] int *permissions)
This function returns the permission word from an input PDF file.
The return value from this function is only valid if
isEncrypted returned non-zero.
The perm* properties can be used to test various
permission bits:
permPrint: printingpermModify: general modificationpermCopy: copy/extract text and graphicspermAnnotate: add annotationspermFormFill: fill form fieldspermAccessibility: extract text and graphics for accessibilitypermAssemble: assemble the documentpermPrintHQ: high-quality printing
Note that all of the permission bit constants are read-only properties
on the COM component, so you'll need to
use pdf.permPrint, etc.
VB6:
Dim in as Long
in = pdf.openInput("c:/test/file.pdf")
If pdf.isEncrypted(in) Then
permissions = pdf.getPermissions(in)
If (permissions And pdf.permPrint) = 0 Then
' not allowed to print
End If
}
