PDFDocument

Zusammenfassung

Allows manipulation of PDF documents, including facilities for merging pages, setting document open behavior, adding file attachments, and creating or changing document security settings

Beschreibung

PDFDocumentOpen and PDFDocumentCreate are two functions that provide a reference to a PDFDocument object.

When using the appendPages, insertPages, or attacheFile methods, it is important to pass a path string to an existing PDF file. If a PDFDocument object is passed, the method will fail. It is also required that PDF security be the same for all documents that are being appended, inserted, or attached. For example, if you want to append three documents into one multipage PDF and only the first document is protected with a password, the other two documents must also first be given the same password before appendPages is used.

Syntax

PDFDocument (pdf_path)
ParameterErläuterungDatentyp
pdf_path

A string that specifies the path and file name for the resulting PDF file when the saveAndClose method is called.

String

The PDFDocumentCreate function receives a path to determine the save location and file name where a new PDF file will be created. However, no PDF file will be created until subsequent steps are performed to insert or append pages and save the PDF file. PDFDocumentCreate will return a PDFDocument object that your script should then manipulate and save. A common scenario for using this function is the creation of a PDF map book. The steps typically involve exporting a number of separate PDF files from map documents, creating a new PDFDocument object, appending content from the exported PDF files and other documents, and saving the final PDF map book.

Please note that it is not possible to create blank PDF files, nor does the PDFDocumentCreate function add any blank pages to the document contents. For the saveAndClose method to successfully create a file, content must be added to the PDFDocument object using the appendPages or insertPages methods.

PDFDocumentCreate example

This script will create a new PDF document, append the contents of three separate PDF documents, and save the resulting PDF file.

import arcpy, os

#Set file name and remove if it already exists
pdfPath = r"C:\Project\ParcelAtlasMapBook.pdf"
if os.path.exists(pdfPath):
    os.remove(pdfPath)

#Create the file and append pages
pdfDoc = arcpy.mapping.PDFDocumentCreate(pdfPath)
pdfDoc.appendPages(r"C:\Project\Title.pdf")
pdfDoc.appendPages(r"C:\Project\ParcelAtlas.pdf")
pdfDoc.appendPages(r"C:\Project\ContactInfo.pdf")

#Commit changes and delete variable reference
pdfDoc.saveAndClose()
del pdfDoc

Methodenübersicht

MethodeErläuterung
appendPages (pdf_path, {input_pdf_password})

Appends one PDF document to the end of another

attachFile (file_path, {description})

Attaches files to existing PDF documents (Attachments are then accessible to users when the PDF file is opened in a PDF viewer application.)

insertPages (pdf_path, {before_page_number}, {input_pdf_password})

Allows inserting the contents of one PDF document at the beginning or in between the pages of another PDFDocument

saveAndClose ()

Saves any changes made to the currently referenced PDFDocument

updateDocProperties ({pdf_title}, {pdf_author}, {pdf_subject}, {pdf_keywords}, {pdf_open_view}, {pdf_layout})

Allows updating of the PDF document metadata and can also set the certain behaviors that will trigger when the document is opened in Adobe Reader or Adobe Acrobat, such as the initial view mode and the page thumbnails view

Provides the mechanism that sets password, encryption, and security restrictions on PDF files.

Methoden

appendPages (pdf_path, {input_pdf_password})
ParameterErläuterungDatentyp
pdf_path

A string that includes the location and name of the input PDF document to be appended

String
input_pdf_password

A string that defines the master password to a protected file

(Der Standardwert ist None)

String

When appending secured PDF documents that each have different security settings, the output settings will be based on the primary document that pages are being appended to. For example, if the document that is being appended to does not have password information saved, but the appended pages do, the resulting document will not have password information saved.

attachFile (file_path, {description})
ParameterErläuterungDatentyp
file_path

A string that includes the location and name of the file to be attached to the PDF document.

String
description

An optional string to be used as a description for the attachment. The user will see this string when viewing the attachment in a PDF viewer application.

String

Use the attachFile method to attach any type of file to a PDF document.

insertPages (pdf_path, {before_page_number}, {input_pdf_password})
ParameterErläuterungDatentyp
pdf_path

A string that includes the location and name of the input PDF document to be inserted.

String
before_page_number

An integer that defines a page number in the currently referenced PDFDocument before which the new page(s) will be inserted. For example, if the before_page_value is 1, the inserted page will be inserted before all pages.

(Der Standardwert ist 1)

String
input_pdf_password

A string that defines the master password to a protected file.

(Der Standardwert ist None)

String

To add pages to the end of the current PDFDocument, use appendPages instead.

When inserting secured PDF documents that have different security settings, the output settings will be based on the primary document that pages are being inserted into. For example, if the document that is being inserted into does not have password information saved, but the inserted pages do, the resulting document will not have password information saved.

saveAndClose ()

The saveAndClose method must be used for changes to be maintained. If a script exits before saveAndClose is executed, changes will not be saved.

updateDocProperties ({pdf_title}, {pdf_author}, {pdf_subject}, {pdf_keywords}, {pdf_open_view}, {pdf_layout})

String

A pdf_open setting of FULL_SCREEN will prompt a warning about full-screen mode when the PDF is opened. Setting pdf_open to a different option will not clear this setting unless pdf_open is set to USE_NONE.

Codebeispiel

PDFDocument example 1

This script will create a new PDF document, append the contents of two separate PDF documents, and save the resulting PDF file.

import arcpy, os

#Set file name and remove if it already exists
pdfPath = r"C:\Project\ParcelAtlasMapBook.pdf"
if os.path.exists(pdfPath):
    os.remove(pdfPath)

#Create the file and append pages
pdfDoc = arcpy.mapping.PDFDocumentCreate(pdfPath)
pdfDoc.appendPages(r"C:\Project\Title.pdf")
pdfDoc.appendPages(r"C:\Project\ParcelAtlas.pdf")

#Commit changes and delete variable reference
pdfDoc.saveAndClose()
del pdfDoc
PDFDocument example 2

The following script modifies the PDF document metadata properties for the document created in example 1 above and sets the style in which the document will open.

import arcpy
pdfDoc = arcpy.mapping.PDFDocumentOpen(r"C:\Project\ParcelAtlasMapBook.pdf")
pdfDoc.updateDocProperties(pdf_title="Atlas Map",
                           pdf_author="ESRI",
                           pdf_subject="Map Book",
                           pdf_keywords="Atlas; Map Books",
                           pdf_open_view="USE_THUMBS",
                           pdf_layout="SINGLE_PAGE")
pdfDoc.saveAndClose()
del pdfDoc
PDFDocument example 3

The following script will set the user password to esri, encrypt the PDF using RC4 compression, and require a password when the document is opened.

import arcpy
pdfDoc = arcpy.mapping.PDFDocumentOpen(r"C:\Project\ParcelAtlasMapBook.pdf")
pdfDoc.updateDocSecurity("master", "user", "RC4", "OPEN")
pdfDoc.saveAndClose()
del pdfDoc
PDFDocument example 4

This last example will append a final page to the end of the already existing multipage document. The master password is required to make this change to a secured PDF document.

import arcpy
pdfDoc = arcpy.mapping.PDFDocumentOpen(r"C:\Project\ParcelAtlasMapBook.pdf", "master")
pdfDoc.appendPages(r"C:\Project\ContactInfo.pdf")
pdfDoc.saveAndClose()
del pdfDoc
