Class: PDFDoc

Core.PDFNet. PDFDoc

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.GetPage(page_num). - To access form fields use pdfdoc.GetFieldIterator(), pdfdoc.GetFieldIterator(name) or pdfdoc.GetField(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.

Methods

<static> create()

Default constructor. Creates an empty new document.
Returns:
A promise that resolves to an object of type: "PDFNet.PDFDoc"
Type
Promise.<Core.PDFNet.PDFDoc>

<static> createDiffOptions()

Method to create a DiffOptions object
Returns:
A promise that resolves to a PDFNet.PDFDoc.DiffOptions.
Type
Promise.<Core.PDFNet.PDFDoc.DiffOptions>

<static> createFromBuffer(buf)

Open a SDF/Cos document from a memory buffer. Note: the document should be fully loaded in the memory buffer. Note: the buffer ownership is not transfered to the document so the user should clean-up any allocated memory if necessary.
Parameters:
Name Type Description
buf ArrayBuffer | Int8Array | Uint8Array | Uint8ClampedArray a memory buffer containing the serialized document
Returns:
A promise that resolves to an object of type: "PDFNet.PDFDoc"
Type
Promise.<Core.PDFNet.PDFDoc>

<static> createFromFilter(stream)

Open an existing PDF document
Parameters:
Name Type Description
stream Core.PDFNet.Filter input stream containing a serialized document. The input stream may be a random-access file, memory buffer, slow HTTP connection etc. Note: if the input stream doesn't support Seek() operation the document will load whole data stream in memory before parsing. In case of linearized PDF, the document may be parsed on-the-fly while it is being loaded in memory. Note that since MappedFile implements Seek() interface, the document does not have to be fully in memory before it is used. Note: Make sure to call InitSecurityHandler() after PDFDoc(...) for encrypted documents. Note: PDFDoc takes the ownership of the stream.
Returns:
A promise that resolves to an object of type: "PDFNet.PDFDoc"
Type
Promise.<Core.PDFNet.PDFDoc>

importPages(page_arr [, import_bookmarks])

The function imports a list of pages to this document. Although a list of pages can be imported using repeated calls to PageInsert(), PageImport will not import duplicate copies of resources that are shared across pages (such as fonts, images, colorspaces etc). Therefore this method is recommended when a page import list consists of several pages that share the same resources.
Parameters:
Name Type Argument Description
page_arr Array.<Core.PDFNet.Page> A list of pages to import. All pages should belong to the same source document.
import_bookmarks boolean <optional>
 An optional flag specifying whether any bookmark items pointing to pages in the import list should be merged with the target (i.e. this) document.

A promise that resolves to a list of imported pages. Note that imported pages are not placed in the document page sequence. This can be done using methods such as PageInsert(), PagePushBack(), etc.
Type
Promise.<Array.<Core.PDFNet.Page>>

initSecurityHandler()

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.

If the security handler was successfully initialized it can be later obtained using GetSecurityHandler() method.
Returns:
A promise that resolves to true if the SecurityHandler was successfully initialized (this may include authentication data collection, verification etc.), false otherwise.
Type
Promise.<boolean>

initStdSecurityHandler(password)

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

isLinearized()

Call this function to determine whether the document is represented in linearized (fast web view) format.
Returns:
A promise that resolves to true if document is stored in fast web view format, false otherwise. Note: any changes to the document can invalidate linearization. The function will return 'true' only if the original document is linearized and if it is not modified. In order to provide good performance over relatively slow communication links, PDFNet can generate PDF documents with linearized objects and hint tables that can allow a PDF viewer application to download and view one page of a PDF file at a time, rather than requiring the entire file (including fonts and images) to be downloaded before any of it can be viewed. To save a document in linearized (fast web view) format you only need to pass 'Doc.SaveOptions.e_linearized' flag in the Save method.
Type
Promise.<boolean>

Returns:
Type
Promise.<void>

lockRead()

Locks the document to prevent competing write threads (using Lock()) from accessing the document at the same time. Other reader threads however, will be allowed to access the document. Threads attempting to obtain write access to the document will wait in suspended state until the thread that owns the lock calls doc.UnlockRead(). 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.
Returns:
Type
Promise.<void>
