appendPagesFromReader(reader, after_page_append=None)[source]

Copy pages from reader to writer. Includes an optional callback parameter which is invoked after pages are appended to the writer.

Parameters

reader – a PdfFileReader object from which to copy page annotations to this writer object. The writer’s annots will then be updated
reference) (writer_pageref (PDF page) – Reference to the page appended to the writer.

Callback after_page_append (function)

Callback function that is invoked after each page is appended to the writer. Callback signature:

cloneDocumentFromReader(reader, after_page_append=None)[source]

Create a copy (clone) of a document from a PDF file reader

Parameters

reader – PDF file reader instance from which the clone should be created.

Callback after_page_append (function)

Callback function that is invoked after each page is appended to the writer. Signature includes a reference to the appended page (delegates to appendPagesFromReader). Callback signature:

param writer_pageref (PDF page reference): Reference to the page just appended to the document.

cloneReaderDocumentRoot(reader)[source]

Copy the reader document root to the writer.

Parameters: reader – PdfFileReader from the document root should be copied.
Callback after_page_append

encrypt(user_pwd, owner_pwd=None, use_128bit=True, permissions_flag=- 1)[source]

Encrypt this PDF file with the PDF Standard encryption handler.

Parameters

user_pwd (str) – The “user password”, which allows for opening and reading the PDF file with the restrictions provided.
owner_pwd (str) – The “owner password”, which allows for opening the PDF files without any restrictions. By default, the owner password is the same as the user password.
use_128bit (bool) – flag as to whether to use 128bit encryption. When false, 40bit encryption will be used. By default, this flag is on.
permissions_flag (unsigned int) – permissions as described in TABLE 3.20 of the PDF 1.7 specification. A bit value of 1 means the permission is grantend. Hence an integer value of -1 will set all flags. Bit position 3 is for printing, 4 is for modifying content, 5 and 6 control annotations, 9 for form fields, 10 for extraction of text and graphics.
