Python / Guides / Access a PDF page
To access a PDF page.
doc = PDFDoc(filename) # Access a PDF page page = doc.GetPage(page_num)
Merge, copy, delete, and rearrange PDF pages
Full code sample which illustrates how to copy pages from one document to another, how to delete, and rearrange pages and how to use ImportPages() method for very efficient copy and merge operations.
A high-level PDF document contains a sequence of Page objects, as illustrated in the following figure:
PDFDoc Page sequence.
To find the number of pages in a PDF document, call
To retrieve a specific page of a document, use
PDFDoc.GetPage(page_num). Page numbers in the document's page sequence are indexed from 1. If the given page number doesn't index a page in the current document,
GetPage(page_num) returns null. For example:
page = doc.GetPage(page_num) if page is None: print("Document does contain page#: %d" % (page_num)) else: print("Document does not contain page#: %d" % (page_num))
GetPage(i) is convenient for retrieving an individual page, it's an inefficient way to enumerate every page of a document. It's better to traverse the pages with a PageIterator.
To do so, simply call
PDFDoc.GetPageIterator(). This returns a PageIterator object, which provides
Current() methods. The following code snippet shows how to print the page size for every page in document page sequence:
itr = doc.GetPageIterator() while itr.HasNext(): mediabox = itr.Current().GetMediaBox() print("Media box: %f, %f, %f, %f", mediabox.x1, mediabox.y1, mediabox.x2, mediabox.y2) itr.Next()
(This code finds the page size using the page's media box, which we'll talk more about in the following sections.)
To jump to a specific page with a PageIterator, call
PDFDoc.GetPageIterator(page_num). If no such page exists, the index of the page will return 0. For example:
itr = doc.GetPageIterator(page_num) if itr.Current().GetIndex() > 0: print("Document does contain page#: %d" % (page_num)) else: print("Document does not contain page#: %d" % (page_num))
