Class API

class Document
__init__(self[, filename])

Constructs a Document object from filename.

Parameters:filename (str) – A string containing the path / name of the document file to be used. The file will be opened and remain open until either explicitely closed (see below) or until end of program. If omitted or None, a new empty PDF document will be created.
Return type:Document
Returns:A Document object.
__init__(self, filetype, stream)

Constructs a Document object from memory area stream.

Parameters:
  • filetype (str) – A string specifying the type of document contained in stream. This may be either something that looks like a filename (e.g. "x.pdf"), in which case MuPDF uses the extension to determine the type, or a mime type like application/pdf. Recommended is using the filename scheme, or even the name of the original file for documentation purposes. But just using strings like "pdf" will also work.
  • stream (bytes) – A memory area representing the content of a supported document type. A type of bytearray is supported, too.
Return type:

Document

Returns:

A Document object.

authenticate(password)

Decrypts the document with the string password. If successful, all of the document’s data can be accessed (e.g. for rendering).

Parameters:password (str) – The password to be used.
Return type:int
Returns:True (1) if decryption with password was successful, False (0) otherwise. If successfull, indicator isEncrypted is set to False.
loadPage(pno = 0)

Loads a Page for further processing like rendering, text searching, etc. See the Page object.

Parameters:pno (int) – page number, zero-based (0 is default and the first page of the document) and < doc.pageCount. If pno < 0, then page pno % pageCount will be loaded (IAW pageCount will be added to pno until the result is no longer negative). For example: to load the last page, you can specify doc.loadPage(-1). After this you have page.number == doc.pageCount - 1.
Return type:Page

Note

Conveniently, pages can also be loaded via indexes over the document: doc.loadPage(n) == doc[n]. Consequently, a document can also be used as an iterator over its pages, e.g. for page in doc: ... and for page in reversed(doc): ... will yield the Pages of doc as page.

getToC(simple = True)

Creates a table of contents out of the document’s outline chain.

Parameters:simple (bool) – Indicates whether a simple or a detailed ToC is required. If simple == False, each entry of the list also contains a dictionary with linkDest details for each outline entry.
Return type:list
Returns:a list of lists. Each entry has the form [lvl, title, page, dest]. Its entries have the following meanings:
  • lvl - hierarchy level (integer). The first entry has hierarchy level 1, and entries in a row increase by at most one level.
  • title - title (string)
  • page - 1-based page number (integer). Page numbers < 1 either indicate a target outside this document or no target at all (see next entry).
  • dest - included only if simple = False is specified. A dictionary containing details of the link destination.
getPagePixmap(pno, *args, **kwargs)

Creates a pixmap from page pno (zero-based). Invokes Page.getPixmap().

Return type:Pixmap
getPageImageList(pno)

PDF only: Return a list of all image descriptions referenced by a page.

Parameters:pno (int) – page number, zero-based. Any value < len(doc) is acceptable.
Return type:list
Returns:a list of images shown on this page. Each entry looks like [xref, smask, width, height, bpc, colorspace, alt. colorspace, name]. Where xref is the image object number, smask is the object number of its soft-mask image (if present), width and height are the image dimensions, bpc denotes the number of bits per component (a typical value is 8), colorspace a string naming the colorspace (like DeviceRGB), alt. colorspace is any alternate colorspace depending on the value of colorspace, and name - which is the symbolic name (str) by which the page references this particular image in its content stream. See below how this information can be used to extract PDF images as separate files. Another demonstration:
>>> doc = fitz.open("pymupdf.pdf")
>>> imglist = doc.getPageImageList(0)
>>> for img in imglist: print img
((241, 0, 1043, 457, 8, 'DeviceRGB', '', 'Im1'))
>>> pix = fitz.Pixmap(doc, 241)
>>> pix
fitz.Pixmap(DeviceRGB, fitz.IRect(0, 0, 1043, 457), 0)
getPageFontList(pno)

PDF only: Return a list of all fonts referenced by the page.

Parameters:pno (int) – page number, zero-based, any value < len(doc).
Return type:list
Returns:a list of fonts referenced by this page. Each entry looks like (xref, ext, type, basefont, name). Where xref is the font object number, ext font file extension, type is the font type (like Type1 or TrueType etc.), basefont is the base font name and name is the reference name, by which the page references it in its contents stream:
>>> doc=fitz.open("pymupdf.pdf")
>>> for f in doc.getPageFontList(85): print(f)
(344, 'pfa', 'Type1', 'HVTNTB+SFSX1000', 'F18')
(343, 'pfa', 'Type1', 'KPGUVC+SFTT1000', 'F16')
(745, 'pfa', 'Type1', 'OBIJJJ+SFRM1440', 'F38')
(470, 'pfa', 'Type1', 'AFLLUK+SFTI1000', 'F49')
(342, 'pfa', 'Type1', 'GWNVMD+SFRM1000', 'F15')
(341, 'pfa', 'Type1', 'MFMRXE+SFBX1000', 'F41')
(523, 'pfa', 'Type1', 'LDRDRB+SFIT1000', 'F74')

Note

Fonts are stored on the document level (like images). The reference name is specific for the page. Other pages may use a different name for the same font. Also note, that a font may appear in this list allthough no text actually uses it. But conversely, every piece of text on the page will refer to exactly one of these entries. Look here for the meaning of Font File Extensions.

Note

For more background see Adobe PDF Reference 1.7 chapters 5.4 to 5.8, pp 410.

getPageText(pno, output = "text")

Extracts the text of a page given its page number pno (zero-based). Invokes Page.getText().

Parameters:
  • pno (int) – Page number, zero-based. Any value < len(doc) is acceptable.
  • output (str) – A string specifying the requested output format: text, html, json or xml. Default is text.
Return type:

str

select(list)

PDF only: Keeps only those pages of the document whose numbers occur in the list. Empty lists or elements outside the range 0 <= page < doc.pageCount will cause a ValueError. For more details see remarks at the bottom or this chapter.

Parameters:list (sequence) – A list (or tuple) of page numbers (zero-based) to be included. Pages not in the list will be deleted (from memory) and become unavailable until the document is reopened. Page numbers can occur multiple times and in any order: the resulting document will reflect the list exactly as specified.
Return type:int
Returns:Zero upon successful execution. All document information will be updated to reflect the new state of the document, like outlines, number and sequence of pages, etc. Changes become permanent only after saving the document. Incremental save is supported.
setMetadata(m)

PDF only: Sets or updates the metadata of the document as specified in m, a Python dictionary. As with method select(), these changes become permanent only when you save the document. Incremental save is supported.

Parameters:m (dict) – A dictionary with the same keys as metadata (see below). All keys are optional. A PDF’s format and encryption method cannot be set or changed, these keys therefore have no effect and will be ignored. If any value should not contain data, do not specify its key or set the value to None. If you use m = {} all metadata information will be cleared to the string "none". If you want to selectively change only some values, modify a copy of doc.metadata and use it as the argument for this method.
Return type:int
Returns:Zero upon successful execution and doc.metadata will be updated.
setToC(toc)

PDF only: Replaces the complete current outline tree (table of contents) with a new one. After successful execution, the new outline tree can be accessed as usual via method getToC() or via property outline. Like with other output-oriented methods, changes become permanent only via save() (incremental save supported). Internally, this method consists of the following two steps. For a demonstration see example below.

Please note, that currently the is_open flag is set to False. Therefore all entries other than level 1 will initially be shown collapsed in PDF readers.

  • Step 1 deletes all existing bookmarks.
  • Step 2 creates a new TOC from the entries contained in toc.
Parameters:toc (sequence) –

A Python nested sequence with all bookmark entries that should form the new table of contents. Each entry is a list with the following format. Output variants of method getToC() are also acceptable as input.

  • [lvl, title, page, dest], where
    • lvl is the hierarchy level (int > 0) of the item, starting with 1 and being at most 1 higher than that of the predecessor,
    • title (str) is the title to be displayed.
    • page (int) is the target page number (attention: 1-based to support getToC()-output), must be in valid page range if positive. Set this to -1 if there is no target, or the target is external.
    • dest (optional) is a dictionary or a number. If a number, it will be interpreted as the desired height (in points) this entry should point to on page in the current document. Use a dictionary (like the one given as output by getToC(simple = False)) if you want to store destinations that are either “named”, or reside outside this documennt (other files, internet resources, etc.).
Return type:int
Returns:outline and getToC() will be updated upon successful execution. The return code will either equal the number of inserted items (len(toc)) or the number of deleted items if toc is an empty sequence.

Note

We currently always set the Outline attribute is_open to False. This shows all entries below level 1 as collapsed.

save(outfile, garbage=0, clean=0, deflate=0, incremental=0, ascii=0, expand=0, linear=0)

PDF only: Saves the document in its current state under the name outfile. A document may have changed for a number of reasons: e.g. after a successful authenticate, a decrypted copy will be saved, and, in addition (even without optional parameters), some basic cleaning may also have occurred, e.g. broken xref tables may have been repaired and earlier incremental changes may have been resolved. If you executed any modifying methods, their results will also be reflected in the saved version.

Parameters:
  • outfile (str) – The file name to save to. Must be different from the original value value if incremental=False. When saving incrementally, garbage and linear must be False / 0 and outfile must equal the original filename (for convenience use doc.name).
  • garbage (int) – Do garbage collection: 0 = none, 1 = remove unused objects, 2 = in addition to 1, compact xref table, 3 = in addition to 2, merge duplicate objects, 4 = in addition to 3, check streams for duplication. Excludes incremental.
  • clean (int) – Clean content streams [1]: 0 / False, 1 / True.
  • deflate (int) – Deflate uncompressed streams: 0 / False, 1 / True.
  • incremental (int) – Only save changed objects: 0 / False, 1 / True. Excludes garbage and linear. Cannot be used for decrypted files and for files opened in repair mode (openErrCode > 0). In these cases saving to a new file is required.
  • ascii (int) – Where possible make the output ASCII: 0 / False, 1 / True.
  • expand (int) – Decompress contents: 0 = none, 1 = images, 2 = fonts, 255 = all. This convenience option generates a decompressed file version that can be better read by some other programs.
  • linear (int) – Save a linearised version of the document: 0 = False, 1 = True. This option creates a file format for improved performance when read via internet connections. Excludes incremental.
Return type:

int

Returns:

Zero upon successful execution.

saveIncr()

PDF only: saves the document incrementally. This is a convenience abbreviation for doc.save(doc.name, incremental = True).

Caution

A PDF may not be encrypted, but still be password protected against changes - see the permissions property. Performing incremental saves if permissions["edit"] == False can lead to unpredictable results. Save to a new file in such a case. We also consider raising an exception under this condition.

searchPageFor(pno, text, hit_max = 16)

Search for text on page number pno. Works exactly like the corresponding Page.searchFor(). Any integer pno < len(doc) is acceptable.

write(garbage=0, clean=0, deflate=0, ascii=0, expand=0, linear=0)

PDF only: Writes the current content of the document to a bytes object instead of to a file like save(). Obviously, you should be wary about memory requirements. The meanings of the parameters exactly equal those in Document.save(). The tutorial contains an example for using this method as a pre-processor to pdfrw.

Return type:bytes
Returns:a bytes object containing the complete document data.
insertPDF(docsrc, from_page = -1, to_page = -1, start_at = -1, rotate = -1, links = True)

PDF only: Copy the page range [from_page, to_page] (including both) of PDF document docsrc into the current one. Inserts will start with page number start_at. Negative values can be used to indicate default values. All pages thus copied will be rotated as specified. Links can be excluded in the target, see below. All page numbers are zero-based.

Parameters:
  • docsrc (Document) – An opened PDF Document which must not be the current document object. However, it may refer to the same underlying file.
  • from_page (int) – First page number in docsrc. Default is zero.
  • to_page (int) – Last page number in docsrc to copy. Default is the last page.
  • start_at (int) – First copied page will become page number start_at in the destination. If omitted, the page range will be appended to current document. If zero, the page range will be inserted before current first page.
  • rotate (int) – All copied pages will be rotated by the provided value (degrees). If you do not specify a value (or -1), the original will not be changed. Otherwise it must be an integer multiple of 90 (not checked). Rotation is counter-clockwise if rotate is positive, else clockwise.
  • links (bool) – Choose whether (internal and external) links should be included with the copy. Default is True. An internal link is always excluded if its destination is not one of the copied pages.
Return type:

int

Returns:

Zero upon successful execution.

Note

If from_page > to_page, pages will be copied in reverse order. If 0 <= from_page == to_page, then one page will be copied.

Note

docsrc bookmarks will not be copied. It is easy however, to recover a table of contents for the resulting document. Look at the examples below and at program PDFjoiner.py in the examples directory: it can join PDF documents and at the same time piece together respective parts of the tables of contents.

insertPage(to = -1, text = None, fontsize = 11, width = 595, height = 842, fontname = "Helvetica", fontfile = None, color = (0, 0, 0))

PDF only: Insert an empty page. Default page dimensions are those of A4 portrait paper format. Optionally, text can also be inserted - provided as a string or asequence.

Parameters:
  • to (int) – page number (0-based) in front of which to insert. Valid specifications must be in range -1 <= pno <= len(doc). The default -1 and pno = len(doc) indicate end of document, i.e. after the last page.
  • text (str or sequence) – optional text to put on the page. If given, it will start at 72 points (one inch) below top and 50 points from left. Line breaks (\n) will be honored, if it is a string. No care will be taken as to whether lines are too wide. However, text output stops when no more lines will fit on the page (discarding any remaining text). If a sequence is specified, its entries must be a of type string. Each entry will be put on one line. Line breaks within an entry will be treated as any other white space. If you want to calculate the number of lines fitting on a page beforehand, use this formula: int((height - 108) / (fontsize * 1.2). So, this methods reserves one inch at the top and 1/2 inches at the bottom of the page as free space.
  • fontsize (float) – font size in pixels. Default is 11. If more than one line is provided, a line spacing of fontsize * 1.2 (fontsize plus 20%) is used.
  • width (float) – width in pixels. Default is 595 (A4 width). Choose 612 for Letter width.
  • height (float) – page height in pixels. Default is 842 (A4 height). Choose 792 for Letter height.
  • fontname (str) – name of one of the PDF Base 14 Fonts (default is “Helvetica”) if fontfile is not specified.
  • fontfile (str) – file path of a font existing on the system. If this parameter is specified, specifying fontname is mandatory. If the font is new to the PDF, it will be embedded. Of the font file, index 0 is used. Be sure to choose a font that supports horizontal, left-to-right spacing.
  • color (sequence) – RGB text color specified as a triple of floats in range 0 to 1. E.g. specify black (default) as (0, 0, 0), red as (1, 0, 0), some gray value as (0.5, 0.5, 0.5), etc.
Return type:

int

Returns:

number of text lines put on the page. Use this to check which part of your text did not fit.

Notes:

This method can be used to

  1. create a PDF containing only one empty page of a given dimension. The size of such a file is well below 500 bytes and hence close to the theoretical PDF minimum.
  2. create a protocol page of which files have been embedded, or separator pages between joined pieces of PDF Documents.
  3. convert textfiles to PDF like in the demo script text2pdf.py.
  4. For now, the inserted text should restrict itself to one byte character codes.
  5. An easy way to create pages with a usual paper format, use a statement like width, height = fitz.PaperSize("A4-L").
  6. To simplify color specification, we provide a Color Database. This allows you to specify color = getColor("turquoise"), without bothering about any more details.
newPage(to = -1, width = 595, height = 842)

PDF only: Convenience method: insert an empty page like insertPage() does. Valid parameters have the same meaning. However, no text can be inserted, instead the inserted page object is returned.

Return type:Page
Returns:the page object just inserted.
deletePage(pno)

PDF only: Delete a page given by its 0-based number in range 0 <= pno < len(doc).

Parameters:pno (int) – the page to be deleted.
deletePageRange(from_page = -1, to_page = -1)

PDF only: Delete a range of pages specified as 0-based numbers. Any negative parameter will first be replaced by len(doc) - 1. After that, condition 0 <= from_page <= to_page < len(doc) must be true. If the parameters are equal, one page will be deleted.

Parameters:
  • from_page (int) – the first page to be deleted.
  • to_page (int) – the last page to be deleted.
copyPage(pno, to = -1)

PDF only: Copy a page within the document.

Parameters:
  • pno (int) – the page to be copied. Number must be in range 0 <= pno < len(doc).
  • to (int) – the page number in front of which to insert the copy. To insert at end of document (default), specify a negative value.
movePage(pno, to = -1)

PDF only: Move (copy and then delete original) page to another location.

Parameters:
  • pno (int) – the page to be moved. Number must be in range 0 <= pno < len(doc).
  • to (int) – the page number in front of which to insert the moved page. To insert at end of document (default), specify a negative value. Must not be in (pno, pno + 1).
embeddedFileInfo(n)

PDF only: Retrieve information of an embedded file identified by either its number or by its name.

Parameters:n (int or str) – index or name of entry. Obviously 0 <= n < embeddedFileCount must be true if n is an integer.
Return type:dict
Returns:a dictionary with the following keys:
  • name - (str) name under which this entry is stored
  • file - (str) filename associated with the entry
  • desc - (str) description of the entry
  • size - (int) original content size
  • length - (int) compressed content length
embeddedFileSetInfo(n, filename = filename, desc = desc)

PDF only: Change some information of an embedded file given its entry number or name. At least one of filename and desc must be specified. Response will be zero if successful, else an exception is raised.

Parameters:
  • n (int or str) – index or name of entry. Obviously 0 <= n < embeddedFileCount must be true if n is an integer.
  • filename (str) – sets the filename of the entry.
  • desc (str) – sets the description of the entry.
embeddedFileGet(n)

PDF only: Retrieve the content of embedded file by its entry number or name. If the document is not a PDF, or entry cannot be found, an exception is raised.

Parameters:n (int or str) – index or name of entry. Obviously 0 <= n < embeddedFileCount must be true if n is an integer.
Return type:bytes (Python 3), str (Python 2)
embeddedFileDel(name)

PDF only: Remove an entry from the portfolio. As always, physical deletion of the embedded file content (and file space regain) will occur when the document is saved to a new file with garbage option. With an incremental save, the associated object will only be marked deleted.

Note

We do not support entry numbers for this function yet. If you need to e.g. delete all embedded files, scan through all embedded files by number, and use the returned dictionary’s name entry to delete each one. This function will delete the first entry with this name it finds. Be wary that for arbitrary PDF files, this may not have been the only one, because PDF itself has no mechanism to prevent duplicate entries …

Parameters:name (str) – name of entry.
embeddedFileAdd(stream, name, filename = filename, desc = desc)

PDF only: Add new content to the document’s portfolio.

Parameters:
  • stream (bytes or bytearray or str (Python 2 only)) – contents
  • name (str) – new entry identifier, must not already exist in embedded files.
  • filename (str) – optional filename or None, documentation only, will be set to name if None or omitted.
  • desc (str) – optional description or None, arbitrary documentation text, will be set to name if None or omitted.
Return type:

int

Returns:

the index given to the new entry. In the current (April 11, 2017) MuPDF version, this is not reliably true (for this reason we have decided to restrict embeddedFileDel() to entries identified by name). Use character string look up to find your entry again. For any error condition, an exception is raised.

close()

Release objects and space allocations associated with the document. If created from a file, also closes filename (releasing control to the OS).

outline

Contains the first Outline entry of the document (or None). Can be used as a starting point to walk through all outline items. Accessing this property for encrypted, not authenticated documents will raise an AttributeError.

Type:Outline
isClosed

False / 0 if document is still open, True / 1 otherwise. If closed, most other attributes and methods will have been deleted / disabled. In addition, Page objects referring to this document (i.e. created with Document.loadPage()) and their dependent objects will no longer be usable. For reference purposes, Document.name still exists and will contain the filename of the original document (if applicable).

Type:bool
isPDF

True if this is a PDF document, else False.

Type:bool
needsPass

Contains an indicator showing whether the document is encrypted (True (1)) or not (False (0)). This indicator remains unchanged - even after the document has been authenticated. Precludes incremental saves if set.

Type:bool
isEncrypted

This indicator initially equals needsPass. After successful authentication, it is set to False to reflect the situation.

Type:bool
permissions

Shows the permissions to access the document. Contains a dictionary likes this:

>>> doc.permissions
{'print': True, 'edit': True, 'note': True, 'copy': True}

The keys have the obvious meaning of permissions to print, change, annotate and copy the document, respectively.

Type:dict
metadata

Contains the document’s meta data as a Python dictionary or None (if isEncrypted = True and needPass=True). Keys are format, encryption, title, author, subject, keywords, creator, producer, creationDate, modDate. All item values are strings or None.

Except format and encryption, the key names correspond in an obvious way to the PDF keys /Creator, /Producer, /CreationDate, /ModDate, /Title, /Author, /Subject, and /Keywords respectively.

  • format contains the PDF version (e.g. ‘PDF-1.6’).

  • encryption either contains None (no encryption), or a string naming an encryption method (e.g. 'Standard V4 R4 128-bit RC4'). Note that an encryption method may be specified even if needsPass = False. In such cases not all permissions will probably have been granted. Check dictionary permissions for details.

  • If the date fields contain valid data (which need not be the case at all!), they are strings in the PDF-specific timestamp format “D:<TS><TZ>”, where

    • <TS> is the 12 character ISO timestamp YYYYMMDDhhmmss (YYYY - year, MM - month, DD - day, hh - hour, mm - minute, ss - second), and
    • <TZ> is a time zone value (time intervall relative to GMT) containing a sign (‘+’ or ‘-‘), the hour (hh), and the minute ('mm', note the apostrophies!).
  • A Paraguayan value might hence look like D:20150415131602-04'00', which corresponds to the timestamp April 15, 2015, at 1:16:02 pm local time Asuncion.

Type:dict
name

Contains the filename or filetype value with which Document was created.

Type:str
pageCount

Contains the number of pages of the document. May return 0 for documents with no pages. Function len(doc) will also deliver this result.

Type:int
openErrCode

If openErrCode > 0, errors have occurred while opening / parsing the document, which usually means document structure issues. In this case incremental save cannot be used.

Type:int
openErrMsg

Contains either an empty string or the last open error message if openErrCode > 0. Together with any other error messages of MuPDF’s C library, it will also appear on SYSERR.

Type:str
embeddedFileCount

Contains the number of files in the embedded / portfolio files list (also known as collection or attached files). If the document is not a PDF, -1 will be returned.

Type:int

Note

For methods that change the structure of a PDF (insertPDF(), select(), copyPage(), deletePage() and others), be aware that objects or properties in your program may have been invalidated or orphaned. Examples are Page objects and their children (links and annotations), variables holding old page counts, tables of content and the like. Remember to keep such variables up to date or delete orphaned objects.

Remarks on select()

Page numbers in the list need not be unique nor be in any particular sequence. This makes the method a versatile utility to e.g. select only the even or the odd pages, re-arrange a document from back to front, duplicate it, and so forth. In combination with text search or extraction you can also omit / include pages with no text or containing a certain text, etc.

You can execute several selections in a row. The document structure will be updated after each method execution.

Any of those changes will become permanent only with a doc.save(). If you have de-selected many pages, consider specifying the garbage option to eventually reduce the resulting document’s size (when saving to a new file).

Also note, that this method preserves all links, annotations and bookmarks that are still valid. In other words: deleting pages only deletes references which point to de-selected pages. Page number of bookmarks (outline items) are automatically updated when a TOC is retrieved again with getToC(). If a bookmark’s destination page happened to be deleted, then its page number in getToC() will be set to -1.

The results of this method can of course also be achieved using combinations of methods copyPage(), deletePage() and movePage(). While there are many cases, when these methods are more practical, select() is easier and safer to use when many pages are involved.

select() Examples

In general, any list of integers within the document’s page range can be used. Here are some illustrations.

Delete pages with no text:

import fitz
doc = fitz.open("any.pdf")
r = list(range(len(doc)))                  # list of page numbers

for page in doc:
    if not page.getText():                 # page contains no text
        r.remove(page.number)              # remove page number from list

if len(r) < len(doc):                      # did we actually delete anything?
    doc.select(r)                          # apply the list
doc.save("out.pdf", garbage = 4)           # save result to new PDF, OR

# update the original document ... *** VERY FAST! ***
doc.saveIncr()

Create a sub document with only the odd pages:

>>> import fitz
>>> doc = fitz.open("any.pdf")
>>> r = list(range(0, len(doc), 2))
>>> doc.select(r)                              # apply the list
>>> doc.save("oddpages.pdf", garbage = 4)      # save sub-PDF of the odd pages

Concatenate a document with itself:

>>> import fitz
>>> doc = fitz.open("any.pdf")
>>> r = list(range(len(doc)))
>>> r += r                                     # turn PDF into a copy of itself
>>> doc.select(r)
>>> doc.save("any+any.pdf")                    # contains doubled <any.pdf>

Create document copy in reverse page order (well, don’t try with a million pages):

>>> import fitz
>>> doc = fitz.open("any.pdf")
>>> r = list(range(len(doc) - 1, -1, -1))
>>> doc.select(r)
>>> doc.save("back-to-front.pdf")

setMetadata() Example

Clear metadata information. If you do this out of privacy / data protection concerns, make sure you save the document as a new file with garbage > 0. Only then the old /Info object will also be physically removed from the file. In this case, you may also want to clear any XML metadata inserted by several PDF editors:

>>> import fitz
>>> doc=fitz.open("pymupdf.pdf")
>>> doc.metadata             # look at what we currently have
{'producer': 'rst2pdf, reportlab', 'format': 'PDF 1.4', 'encryption': None, 'author':
'Jorj X. McKie', 'modDate': "D:20160611145816-04'00'", 'keywords': 'PDF, XPS, EPUB, CBZ',
'title': 'The PyMuPDF Documentation', 'creationDate': "D:20160611145816-04'00'",
'creator': 'sphinx', 'subject': 'PyMuPDF 1.9.1'}
>>> doc.setMetadata({})      # clear all fields
0
>>> doc.metadata             # look again to show what happened
{'producer': 'none', 'format': 'PDF 1.4', 'encryption': None, 'author': 'none',
'modDate': 'none', 'keywords': 'none', 'title': 'none', 'creationDate': 'none',
'creator': 'none', 'subject': 'none'}
>>> doc._delXmlMetadata()    # clear any XML metadata
0
>>> doc.save("anonymous.pdf", garbage = 4)       # save anonymized doc
0

setToC() Example

This shows how to modify or add a table of contents. Also have a look at csv2toc.py and toc2csv.py in the examples directory:

>>> import fitz
>>> doc = fitz.open("test.pdf")
>>> toc = doc.getToC()
>>> for t in toc: print(t)                           # show what we have
[1, 'The PyMuPDF Documentation', 1]
[2, 'Introduction', 1]
[3, 'Note on the Name fitz', 1]
[3, 'License', 1]
>>> toc[1][1] += " modified by setToC"               # modify something
>>> doc.setToC(toc)                                  # replace outline tree
3                                                    # number of bookmarks inserted
>>> for t in doc.getToC(): print(t)                  # demonstrate it worked
[1, 'The PyMuPDF Documentation', 1]
[2, 'Introduction modified by setToC', 1]            # <<< this has changed
[3, 'Note on the Name fitz', 1]
[3, 'License', 1]

insertPDF() Examples

(1) Concatenate two documents including their TOCs:

>>> doc1 = fitz.open("file1.pdf")          # must be a PDF
>>> doc2 = fitz.open("file2.pdf")          # must be a PDF
>>> pages1 = len(doc1)                     # save doc1's page count
>>> toc1 = doc1.getToC(simple = False)     # save TOC 1
>>> toc2 = doc2.getToC(simple = False)     # save TOC 2
>>> doc1.insertPDF(doc2)                   # doc2 at end of doc1
>>> for t in toc2:                         # increase toc2 page numbers
        t[2] += pages1                     # by old len(doc1)
>>> doc1.setToC(toc1 + toc2)               # now result has total TOC

Obviously, similar ways can be found in more general situations. Just make sure that hierarchy levels in a row do not increase by more than one. Inserting dummy bookmarks before and after toc2 segments would heal such cases. A ready-to-use GUI (wxPython) solution can be found in script PDFjoiner.py of the examples directory.

(2) More examples:

>>> # insert 5 pages of doc2, where its page 21 becomes page 15 in doc1
>>> doc1.insertPDF(doc2, from_page = 21, to_page = 25, start_at = 15)
>>> # same example, but pages are rotated and copied in reverse order
>>> doc1.insertPDF(doc2, from_page = 25, to_page = 21, start_at = 15, rotate = 90)
>>> # put copied pages in front of doc1
>>> doc1.insertPDF(doc2, from_page = 21, to_page = 25, start_at = 0)

Other Examples

Extract all page-referenced images of a PDF into separate PNG files:

for i in range(len(doc)):
    imglist = doc.getPageImageList(i)
    for img in imglist:
        xref = img[0]                  # xref number
        pix = fitz.Pixmap(doc, xref)   # make pixmap from image
        if pix.n - pix.alpha < 4:      # can be saved as PNG
            pix.writePNG("p%s-%s.png" % (i, xref))
        else:                          # CMYK: must convert first
            pix0 = fitz.Pixmap(fitz.csRGB, pix)
            pix0.writePNG("p%s-%s.png" % (i, xref))
            pix0 = None                # free Pixmap resources
        pix = None                     # free Pixmap resources

Rotate all pages of a PDF:

>>> for page in doc: page.setRotation(90)

Footnotes

[1]Content streams describe what (e.g. text or images) appears where and how on a page. PDF uses a specialized mini language similar to PostScript to do this (pp. 985 in Adobe PDF Reference 1.7), which gets interpreted when a page is loaded.
