new PDFDoc()
PDFDoc is a high-level class describing a single PDF (Portable Document Format) document. Most applications using PDFNet will use this class to open existing PDF documents, or to create new PDF documents from scratch.
The class offers a number of entry points into the document. For example,
- To access pages use pdfdoc.GetPageIterator() or pdfdoc.PageFind(page_num).
- To access form fields use pdfdoc.GetFieldIterator() or pdfdoc.FieldFind(name).
- To access document's meta-data use pdfdoc.GetDocInfo().
- To access the outline tree use pdfdoc.GetFirstBookmark().
- To access low-level Document Catalog use pdfdoc.GetRoot(). ...
The class also offers utility methods to slit and merge PDF pages, to create new pages, to flatten forms, to change security settings, etc.

initSecurityHandler(custom_data)
-
Initializes document's SecurityHandler. This version of InitSecurityHandler() works with Standard and Custom PDF security and can be used in situations where the password is obtained dynamically via user feedback. See EncTest sample for example code.
This function should be called immediately after an encrypted document is opened. The function does not have any side effects on documents that are not encrypted.
If the security handler was successfully initialized it can be later obtained using GetSecurityHandler() method.
Parameters:
Name Type Description custom_data
Returns:
true if the SecurityHandler was successfully initialized (this may include authentication data collection, verification etc.), false otherwise.
- Type
- boolean
-
initStdSecurityHandler(password, password_sz)
-
Initializes document's SecurityHandler using the supplied password. This version of InitSecurityHandler() assumes that document uses Standard security and that a password is specified directly.
This function should be called immediately after an encrypted document is opened. The function does not have any side effects on documents that are not encrypted.
If the security handler was successfully initialized, it can be later obtained using GetSecurityHandler() method.
Parameters:
Name Type Description password

If the security handler was successfully initialized, it can be later obtained using GetSecurityHandler() method.
Parameters:
Name Type Description password_buf
Array Specifies the password used to open the document without any user feedback. If you would like to dynamically obtain the password, you need to derive a custom class from StdSecurityHandler() and use InitSecurityHandler() without any parameters. See EncTest sample for example code.

Note: To avoid deadlocks obtaining a write lock while holding a read lock is not permitted and will throw an exception. If this situation is encountered please either unlock the read lock before the write lock is obtained or acquire a write lock (rather than read lock) in the first place.
