* Updated README and package summary description.
*
Fixed a problem on some Linux installations with Python-3.10
(and possibly earlier versions) where `import fitz` failed with
`ImportError: libcrypt.so.2: cannot open shared object file: No such
file or directory`.
*
Fixed `incompatible architecture` error on MacOS arm64.
*
Fixed installation warning from Poetry about missing entry in wheels'
RECORD files.
**Changes in version 1.23.0 (2023-08-22)**
* Add method `find_tables()` to the `Page` object.
This allows locating tables on any supported document page, and
extracting table content by cell.
* New "rebased" implementation of PyMuPDF.
The rebased implementation is available as Python module
`fitz_new`. It can be used as a drop-in replacement with `import
fitz_new as fitz`.
*
Python-independent MuPDF libraries are now in a second wheel called
`PyMuPDFb` that will be automatically installed by pip.
This is to save space on pypi.org - a full release only needs one
`PyMuPDFb` wheel for each OS.
* Bug fixes:
* **Fixed** `#2542 <https://github.com/pymupdf/PyMuPDF/issues/2542>`_: fitz.utils.scrub AttributeError Annot object has no attribute fileUpd inside
* **Fixed** `#2533 <https://github.com/pymupdf/PyMuPDF/issues/2533>`_: get_texttrace returned a incorrect character bbox
* **Fixed** `#2537 <https://github.com/pymupdf/PyMuPDF/issues/2537>`_: Validation when setting a grouped RadioButton throws a RuntimeError: path to 'V' has indirects
* Other changes:
* Dropped support for Python-3.7.
* Fix for wrong page / annot `/Contents` cleaning.
We need to set `pdf_filter_options::no_update` to zero.
* Added new function get_tessdata().
* Cope with problem `/Annot` arrays.
When copying page annotations in method Document.insert_pdf we
previously did not check the validity of members of the `/Annots`
array. For faulty members (like null or non-dictionary items) this
could cause unnecessary exceptions. This fix implements more checks
and skips such array items.
* Additional annotation type checks.
We did not previously check for annotation type when getting /
setting annotation border properties. This is now checked in
accordance with MuPDF.
* Increase fault tolerance.
Avoid exceptions in method `insert_pdf()` when source pages contains
invalid items in the `/Annots` array.
* Return empty border dict for applicable annots.
We previously were returning a non-empty border dictionary even for
non-applicable annotation types. We now return the empty dictionary
`{}` in these cases. This requires some corresponding changes in the
annotation `.update()` method, namely for dashes and border width.
* Restrict `set_rect` to applicable annot types.
We were insufficiently excluding non-applicable annotation types
from `set_rect()` method. We now let MuPDF catch unsupported
annotations and return `False` in these cases.
* Wrong fontsize computation in `page.get_texttrace()`.
When computing the font size we were using the final text
transformation matrix, where we should have taken `span->trm`
instead. This is corrected here.
* Updates to cope with changes to latest MuPDF.
`pdf_lookup_anchor()` has been removed.
* Update fill_textbox to better respect rect.width
The function norm_words in fill_textbox had a bug in its last
loop, appending n+1 characters when actually measuring width of n
characters. It led to a bug in fill_texbox when you tried to write
a single word mostly composed of "wide" letters (M,m, W, w...),
causing the written text to exceed the given rect.
The fix was just to replace n+1 by n.
* Add `script_focus` and `script_blur` options to widget.
**Changes in version 1.22.5 (2023-06-21)**
* This release uses ``MuPDF-1.22.2``.
* Bug fixes:
* **Fixed** `#2365 <https://github.com/pymupdf/PyMuPDF/issues/2365>`_: Incorrect dictionary values for type "fs" drawings.

The :attr:`Annot.border` property has the new item `clouds`,
and method :meth:`Annot.set_border` supports the corresponding `clouds` argument.
* **Changed** Radio button widgets in the same RB group
are now consistently updated **if the group is defined in the standard way**.
* **Added** Support for the `/Locked` key in PDF Optional Content.

* Added ``.github/workflows/build_wheels.yml`` to control building of wheels on Github.
------
**Changes in Version 1.19.6**
* **Fixed** `#1620 <https://github.com/pymupdf/PyMuPDF/issues/1620>`_. The :ref:`TextPage` created by :meth:`Page.get_textpage` will now be freed correctly (removed memory leak).
* **Fixed** `#1601 <https://github.com/pymupdf/PyMuPDF/issues/1601>`_. Document open errors should now be more concise and easier to interpret. In the course of this, two PyMuPDF-specific Python exceptions have been **added:**
- ``EmptyFileError`` -- raised when trying to create a :ref:`Document` (``fitz.open()``) from an empty file or zero-length memory.
- ``FileDataError`` -- raised when MuPDF encounters irrecoverable document structure issues.
* **Added** :meth:`Page.load_widget` given a PDF field's xref.
* **Added** Dictionary :attr:`pdfcolor` which provide the about 500 colors defined as PDF color values with the lower case color name as key.
* **Added** algebra functionality to the :ref:`Quad` class. These objects can now also be added and subtracted among themselves, and be multiplied by numbers and matrices.
* **Added** new constants defining the default text extraction flags for more comfortable handling. Their naming convention is like :data:`TEXTFLAGS_WORDS` for ``page.get_text("words")``. See :ref:`text_extraction_flags`.
* **Changed** :meth:`Page.annots` and :meth:`Page.widgets` to detect and prevent reloading the page (illegally) inside the iterator loops via :meth:`Document.reload_page`. Doing this brings down the interpretor. Documented clean ways to do annotation and widget mass updates within properly designed loops.
* **Changed** several internal utility functions to become standalone ("SWIG inline") as opposed to be part of the :ref:`Tools` class. This, among other things, increases the performance of geometry object creation.
* **Changed** :meth:`Document.update_stream` to always accept stream updates - whether or not the dictionary object behind the xref already is a stream. Thus the former ``new`` parameter is now ignored and will be removed in v1.20.0.
------
**Changes in Version 1.19.5**
* **Fixed** `#1518 <https://github.com/pymupdf/PyMuPDF/issues/1518>`_. A limited "fix": in some cases, rectangles and quadrupels were not correctly encoded to support re-drawing by :ref:`Shape`.
* **Fixed** `#1521 <https://github.com/pymupdf/PyMuPDF/issues/1521>`_. This had the same ultimate reason behind issue #1510.
* **Fixed** `#1513 <https://github.com/pymupdf/PyMuPDF/issues/1513>`_. Some Optional Content functions did not support non-ASCII characters.
* **Fixed** `#1510 <https://github.com/pymupdf/PyMuPDF/issues/1510>`_. Support more soft-mask image subtypes.
* **Fixed** `#1507 <https://github.com/pymupdf/PyMuPDF/issues/1507>`_. Immunize against items in the outlines chain, that are ``"null"`` objects.
* **Fixed** re-opened `#1417 <https://github.com/pymupdf/PyMuPDF/issues/1417>`_. ("too many open files"). This was due to insufficient calls to MuPDF's ``fz_drop_document()``. This also fixes `#1550 <https://github.com/pymupdf/PyMuPDF/issues/1550>`_.
* **Fixed** several undocumented issues in relation to incorrectly setting the text span origin :data:`point_like`.
* **Fixed** undocumented error computing the character bbox in method :meth:`Page.get_texttrace` when text is **flipped** (as opposed to just rotated).
* **Added** items to the dictionary returned by :meth:`image_properties`: ``orientation`` and ``transform`` report the natural image orientation (EXIF data).
* **Added** method :meth:`Document.xref_copy`. It will make a given target PDF object an exact copy of a source object.
------
**Changes in Version 1.19.4**
* **Fixed** `#1505 <https://github.com/pymupdf/PyMuPDF/issues/1505>`_. Immunize against circular outline items.
* **Fixed** `#1484 <https://github.com/pymupdf/PyMuPDF/issues/1484>`_. Correct CropBox coordinates are now returned in all situations.
* **Fixed** `#1479 <https://github.com/pymupdf/PyMuPDF/issues/1479>`_.
* **Fixed** `#1474 <https://github.com/pymupdf/PyMuPDF/issues/1474>`_. TextPage objects are now properly deleted again.
* **Added** :ref:`Page` methods and attributes for PDF ``/ArtBox``, ``/BleedBox``, ``/TrimBox``.
* **Added** global attribute :attr:`TESSDATA_PREFIX` for easy checking of OCR support.
* **Changed** :meth:`Document.xref_set_key` such that dictionary keys will physically be removed if set to value ``"null"``.
* **Changed** :meth:`Document.extract_font` to optionally return a dictionary (instead of a tuple).
------
**Changes in Version 1.19.3**
This patch version implements minor improvements for :ref:`Pixmap` and also some important fixes.
* **Fixed** `#1351 <https://github.com/pymupdf/PyMuPDF/discussions/1351>`_. Reverted code that introduced the memory growth in v1.18.15.
* **Fixed** `#1417 <https://github.com/pymupdf/PyMuPDF/discussions/1417>`_. Developped circumvention for growth of open file handles using :meth:`Document.insert_pdf`.
* **Fixed** `#1418 <https://github.com/pymupdf/PyMuPDF/discussions/1418>`_. Developped circumvention for memory growth using :meth:`Document.insert_pdf`.
* **Fixed** `#1430 <https://github.com/pymupdf/PyMuPDF/discussions/1430>`_. Developped circumvention for mass pixmap generations of document pages.
* **Fixed** `#1433 <https://github.com/pymupdf/PyMuPDF/discussions/1433>`_. Solves a bbox error for some Type 3 font in PyMuPDF text processing.
* **Added** :meth:`Pixmap.color_topusage` to determine the share of the most frequently used color. Solves `#1397 <https://github.com/pymupdf/PyMuPDF/discussions/1397>`_.
* **Added** :meth:`Pixmap.warp` which makes a new pixmap from a given arbitrary convex quad inside the pixmap.
* **Added** :attr:`Annot.irt_xref` and :meth:`Annot.set_irt_xref` to inquire or set the `/IRT` ("In Responde To") property of an annotation. Implements `#1450 <https://github.com/pymupdf/PyMuPDF/discussions/1450>`_.
* **Added** :meth:`Rect.torect` and :meth:`IRect.torect` which compute a matrix that transforms to a given other rectangle.
* **Changed** :meth:`Pixmap.color_count` to also return the count of each color.
* **Changed** :meth:`Page.get_texttrace` to also return correct span and character bboxes if ``span["dir"] != (1, 0)``.
------
**Changes in Version 1.19.2**
This patch version implements minor improvements for :meth:`Page.get_drawings` and also some important fixes.
* **Fixed** `#1388 <https://github.com/pymupdf/PyMuPDF/discussions/1388>`_. Fixed intermittent memory corruption when insert or updating annotations.
* **Fixed** `#1375 <https://github.com/pymupdf/PyMuPDF/discussions/1375>`_. Inconsistencies between line numbers as returned by the "words" and the "dict" options of :meth:`Page.get_text` have been corrected.
* **Fixed** `#1364 <https://github.com/pymupdf/PyMuPDF/issues/1342>`_. The check for being a ``"rawdict"`` span in :meth:`recover_span_quad` now works correctly.
* **Fixed** `#1342 <https://github.com/pymupdf/PyMuPDF/issues/1364>`_. Corrected the check for rectangle infiniteness in :meth:`Page.show_pdf_page`.
* **Changed** :meth:`Page.get_drawings`, :meth:`Page.get_cdrawings` to return an indicator on the area orientation covered by a rectangle. This implements `#1355 <https://github.com/pymupdf/PyMuPDF/issues/1355>`_. Also, the recognition rate for rectangles and quads has been significantly improved.
* **Changed** all text search and extraction methods to set the new ``flags`` option ``TEXT_MEDIABOX_CLIP`` to ON by default. That bit causes the automatic suppression of all characters that are completely outside a page's mediabox (in as far as that notion is supported for a document type). This eliminates the need for using ``clip=page.rect`` or similar for omitting text outside the visible area.
* **Added** parameter ``"dpi"`` to :meth:`Page.get_pixmap` and :meth:`Annot.get_pixmap`. When given, parameter ``"matrix"`` is ignored, and a :ref:`Pixmap` with the desired dots per inch is created.
* **Added** attributes :attr:`Pixmap.is_monochrome` and :attr:`Pixmap.is_unicolor` allowing fast checks of pixmap properties. Addresses `#1397 <https://github.com/pymupdf/PyMuPDF/discussions/1397>`_.
* **Added** method :meth:`Pixmap.color_count` to determine the unique colors in the pixmap.
* **Added** boolean parameter ``"compress"`` to PDF document method :meth:`Document.update_stream`. Addresses / enables solution for `#1408 <https://github.com/pymupdf/PyMuPDF/discussions/1408>`_.
------
**Changes in Version 1.19.1**
This is the first patch version to support MuPDF v1.19.0. Apart from one bug fix, it includes important improvements for OCR support and the option to **sort extracted text** to the standard reading order "from top-left to bottom-right".
* **Fixed** `#1328 <https://github.com/pymupdf/PyMuPDF/issues/1328>`_. "words" text extraction again returns correct ``(x0, y0)`` coordinates.
* **Changed** :meth:`Page.get_textpage_ocr`: it now supports parameter ``dpi`` to control OCR quality. It is also possible to choose whether the **full page** should be OCRed or **only the images displayed** by the page.
* **Changed** :meth:`Page.get_drawings` and :meth:`Page.get_cdrawings` to automatically convert colors to RGB color tuples. Implements `#1332 <https://github.com/pymupdf/PyMuPDF/discussions/1332>`_. Similar change was applied to :meth:`Page.get_texttrace`.
* **Changed** :meth:`Page.get_text` to support a parameter ``sort``. If set to ``True`` the output is conveniently sorted.
------
**Changes in Version 1.19.0**
This is the first version supporting MuPDF 1.19.*, published 2021-10-05. It introduces many new features compared to the previous version 1.18.*.
PyMuPDF has now picked up integrated Tesseract OCR support, which was already present in MuPDF v1.18.0.
* Supported images can be OCRed via their :ref:`Pixmap` which results in a 1-page PDF with a text layer.
* All supported document pages (i.e. not only PDFs), can be OCRed using specialized text extraction methods. The result is a mixture of standard and OCR text (depending on which part of the page was deemed to require OCRing) that can be searched and extracted without restrictions.
* All this requires an independent installation of Tesseract. MuPDF actually (only) needs the location of Tesseract's ``"tessdata"`` folder, where its language support data are stored. This location must be available as environment variable ``TESSDATA_PREFIX``.
A new MuPDF feature is **journalling PDF updates**, which is also supported by this PyMuPDF version. Changes may be logged, rolled back or replayed, allowing to implement a whole new level of control over PDF document integrity -- similar to functions present in modern database systems.
A third feature (unrelated to the new MuPDF version) includes the ability to detect when page **objects cover or hide each other**. It is now e.g. possible to see that text is covered by a drawing or an image.
* **Changed** terminology and meaning of important geometry concepts: Rectangles are now characterized as *finite*, *valid* or *empty*, while the definitions of these terms have also changed. Rectangles specifically are now thought of being "open": not all corners and sides are considered part of the retangle. Please do read the :ref:`Rect` section for details.
* **Added** new parameter `"no_new_id"` to :meth:`Document.save` / :meth:`Document.tobytes` methods. Use it to suppress updating the second item of the document ``/ID`` which in PDF indicates that the original file has been updated. If the PDF has no ``/ID`` at all yet, then no new one will be created either.
* **Added** a **journalling facility** for PDF updates. This allows logging changes, undoing or redoing them, or saving the journal for later use. Refer to :meth:`Document.journal_enable` and friends.
* **Added** new :ref:`Pixmap` methods :meth:`Pixmap.pdfocr_save` and :meth:`Pixmap.pdfocr_tobytes`, which generate a 1-page PDF containing the pixmap as PNG image with OCR text layer.
* **Added** :meth:`Page.get_textpage_ocr` which executes optical character recognition for the page, then extracts the results and stores them together with "normal" page content in a :ref:`TextPage`. Use or reuse this object in subsequent text extractions and text searches to avoid multiple efforts. The existing text search and text extraction methods have been extended to support a separately created textpage -- see next item.
* **Added** a new parameter ``textpage`` to text extraction and text search methods. This allows reuse of a previously created :ref:`TextPage` and thus achieves significant runtime benefits -- which is especially important for the new OCR features. But "normal" text extractions can definitely also benefit.
* **Added** :meth:`Page.get_texttrace`, a technical method delivering low-level text character properties. It was present before as a private method, but the author felt it now is mature enough to be officially available. It specifically includes a "sequence number" which indicates the page appearance build operation that painted the text.
* **Added** :meth:`Page.get_bboxlog` which delivers the list of rectangles of page objects like text, images or drawings. Its significance lies in its sequence: rectangles intersecting areas with a lower index are covering or hiding them.
* **Changed** methods :meth:`Page.get_drawings` and :meth:`Page.get_cdrawings` to include a "sequence number" indicating the page appearance build operation that created the drawing.
* **Fixed** `#1311 <https://github.com/pymupdf/PyMuPDF/issues/1311>`_. Field values in comboboxes should now be handled correctly.
* **Fixed** `#1290 <https://github.com/pymupdf/PyMuPDF/issues/1290>`_. Error was caused by incorrect rectangle emptiness check, which is fixed due to new geometry logic of this version.
* **Fixed** `#1286 <https://github.com/pymupdf/PyMuPDF/issues/1286>`_. Text alignment for redact annotations is working again.
* **Fixed** `#1287 <https://github.com/pymupdf/PyMuPDF/issues/1287>`_. Infinite loop issue for non-Windows systems when applying some redactions has been resolved.
* **Fixed** `#1284 <https://github.com/pymupdf/PyMuPDF/issues/1284>`_. Text layout destruction after applying redactions in some cases has been resolved.
------
**Changes in Version 1.18.18 / 1.18.19**
* **Fixed** issue `#1266 <https://github.com/pymupdf/PyMuPDF/issues/1266>`_. Failure to set :attr:`Pixmap.samples` in important cases, was hotfixed in a new version 1.18.19.
* **Fixed** issue `#1257 <https://github.com/pymupdf/PyMuPDF/issues/1257>`_. Removing the read-only flag from PDF fields is now possible.
* **Fixed** issue `#1252 <https://github.com/pymupdf/PyMuPDF/issues/1252>`_. Now correctly specifying the ``zoom`` value for PDF link annotations.
* **Fixed** issue `#1244 <https://github.com/pymupdf/PyMuPDF/issues/1244>`_. Now correctly computing the transform matrix in :meth:`Page.get_image__bbox`.
* **Fixed** issue `#1241 <https://github.com/pymupdf/PyMuPDF/issues/1241>`_. Prevent returning artifact characters in :meth:`Page.get_textbox`, which happened in certain constellations.
* **Fixed** issue `#1234 <https://github.com/pymupdf/PyMuPDF/issues/1234>`_. Avoid creating infinite rectangles in corner cases -- :meth:`Page.get_drawings`, :meth:`Page.get_cdrawings`.
* **Added** test data and test scripts to the source PyPI source distribution.
------
**Changes in Version 1.18.17**
Focus of this version are major performance improvements of selected functions.
* **Fixed** issue `#1199 <https://github.com/pymupdf/PyMuPDF/issues/1199>`_. Using a non-existing page number in :meth:`Document.get_page_images` and friends will no longer lead to segfaults.
* **Changed** :meth:`Page.get_drawings` to now differentiate between "stroke", "fill" and combined paths. Paths containing more than one rectangle (i.e. "re" items) are now supported. Extracting "clipped" paths is now available as an option.
* **Added** :meth:`Page.get_cdrawings`, performance-optimized version of :meth:`Page.get_drawings`.
* **Added** :attr:`Pixmap.samples_mv`, *memoryview* of a pixmap's pixel area. Does not copy and thus always accesses the current state of that area.
* **Added** :attr:`Pixmap.samples_ptr`, Python "pointer" to a pixmap's pixel area. Allows much faster creation (factor 800+) of Qt images.
------
**Changes in Version 1.18.16**
* **Fixed** issue `#1184 <https://github.com/pymupdf/PyMuPDF/issues/1184>`_. Existing PDF widget fonts in a PDF are now accepted (i.e. not forcedly changed to a Base-14 font).
* **Fixed** issue `#1154 <https://github.com/pymupdf/PyMuPDF/issues/1154>`_. Text search hits should now be correct when ``clip`` is specified.
* **Fixed** issue `#1152 <https://github.com/pymupdf/PyMuPDF/issues/1152>`_.
* **Fixed** issue `#1146 <https://github.com/pymupdf/PyMuPDF/issues/1146>`_.
* **Added** :attr:`Link.flags` and :meth:`Link.set_flags` to the :ref:`Link` class. Implements enhancement requests `#1187 <https://github.com/pymupdf/PyMuPDF/issues/1187>`_.
* **Added** option to *simulate* :meth:`TextWriter.fill_textbox` output for predicting the number of lines, that a given text would occupy in the textbox.
* **Added** text output support as subcommand `gettext` to the ``fitz`` CLI module. Most importantly, original **physical text layout** reproduction is now supported.
------
**Changes in Version 1.18.15**
* **Fixed** issue `#1088 <https://github.com/pymupdf/PyMuPDF/issues/1088>`_. Removing an annotation's fill color should now work again both ways, using the ``fill_color=[]`` argument in :meth:`Annot.update` as well as ``fill=[]`` in :meth:`Annot.set_colors`.
* **Fixed** issue `#1081 <https://github.com/pymupdf/PyMuPDF/issues/1081>`_. :meth:`Document.subset_fonts`: fixed an error which created wrong character widths for some fonts.
* **Fixed** issue `#1078 <https://github.com/pymupdf/PyMuPDF/issues/1078>`_. :meth:`Page.get_text` and other methods related to text extraction: changed the default value of the :ref:`TextPage` ``flags`` parameter. All whitespace and :data:`ligatures` are now preserved.
* **Fixed** issue `#1085 <https://github.com/pymupdf/PyMuPDF/issues/1085>`_. The old *snake_cased* alias of ``fitz.detTextlength`` is now defined correctly.
* **Changed** :meth:`Document.subset_fonts` will now correctly prefix font subsets with an appropriate six letter uppercase tag, complying with the PDF specification.
* **Added** new method :meth:`Widget.button_states` which returns the possible values that a button-type field can have when being set to "on" or "off".
* **Added** support of text with **Small Capital** letters to the :ref:`Font` and :ref:`TextWriter` classes. This is reflected by an additional bool parameter ``small_caps`` in various of their methods.
------
**Changes in Version 1.18.14**
* **Finished** implementing new, "snake_cased" names for methods and properties, that were "camelCased" and awkward in many aspects. At the end of this documentation, there is section :ref:`Deprecated` with more background and a mapping of old to new names.
* **Fixed** issue `#1053 <https://github.com/pymupdf/PyMuPDF/issues/1053>`_. :meth:`Page.insert_image`: when given, include image mask in the hash computation.
* **Fixed** issue `#1043 <https://github.com/pymupdf/PyMuPDF/issues/1043>`_. Added ``Pixmap.getPNGdata`` to the aliases of :meth:`Pixmap.tobytes`.
* **Fixed** an internal error when computing the enveloping rectangle of drawn paths as returned by :meth:`Page.get_drawings`.
* **Fixed** an internal error occasionally causing loops when outputting text via :meth:`TextWriter.fill_textbox`.
* **Added** :meth:`Font.char_lengths`, which returns a tuple of character widths of a string.
* **Added** more ways to specify pages in :meth:`Document.delete_pages`. Now a sequence (list, tuple or range) can be specified, and the Python ``del`` statement can be used. In the latter case, Python ``slices`` are also accepted.
* **Changed** :meth:`Document.del_toc_item`, which disables a single item of the TOC: previously, the title text was removed. Instead, now the complete item will be shown grayed-out by supporting viewers.
------
**Changes in Version 1.18.13**
* **Fixed** issue `#1014 <https://github.com/pymupdf/PyMuPDF/issues/1014>`_.
* **Fixed** an internal memory leak when computing image bboxes -- :meth:`Page.get_image_bbox`.
* **Added** support for low-level access and modification of the PDF trailer. Applies to :meth:`Document.xref_get_keys`, :meth:`Document.xref_get_key`, and :meth:`Document.xref_set_key`.
* **Added** documentation for maintaining private entries in PDF metadata.
* **Added** documentation for handling transparent image insertions, :meth:`Page.insert_image`.
* **Added** :meth:`Page.get_image_rects`, an improved version of :meth:`Page.get_image_bbox`.
* **Changed** :meth:`Document.delete_pages` to support various ways of specifying pages to delete. Implements `#1042 <https://github.com/pymupdf/PyMuPDF/issues/1042>`_.
* **Changed** :meth:`Page.insert_image` to also accept the xref of an existing image in the file. This allows "copying" images between pages, and extremely fast mutiple insertions.
* **Changed** :meth:`Page.insert_image` to also accept the integer parameter ``alpha``. To be used for performance improvements.
* **Changed** :meth:`Pixmap.set_alpha` to support new parameters for pre-multiplying colors with their alpha values and setting a specific color to fully transparent (e.g. white).
* **Changed** :meth:`Document.embfile_add` to automatically set creation and modification date-time. Correspondingly, :meth:`Document.embfile_upd` automatically maintains modification date-time (``/ModDate`` PDF key), and :meth:`Document.embfile_info` correspondingly reports these data. In addition, the embedded file's associated "collection item" is included via its :data:`xref`. This supports the development of PDF portfolio applications.
------
**Changes in Version 1.18.11 / 1.18.12**
* **Fixed** issue `#972 <https://github.com/pymupdf/PyMuPDF/issues/972>`_. Improved layout of source distribution material.
* **Fixed** issue `#962 <https://github.com/pymupdf/PyMuPDF/issues/962>`_. Stabilized Linux distribution detection for generating PyMuPDF from sources.
* **Added:** :meth:`Page.get_xobjects` delivers the result of :meth:`Document.get_page_xobjects`.
* **Added:** :meth:`Page.get_image_info` delivers meta information for all images shown on the page.
* **Added:** :meth:`Tools.mupdf_display_warnings` allows setting on / off the display of MuPDF-generated warnings. The default is off.
* **Added:** :meth:`Document.ez_save` convenience alias of :meth:`Document.save` with some different defaults.
* **Changed:** Image extractions of document pages now also contain the image's **transformation matrix**. This concerns :meth:`Page.get_image_bbox` and the DICT, JSON, RAWDICT, and RAWJSON variants of :meth:`Page.get_text`.
------
**Changes in Version 1.18.10**
* **Fixed** issue `#941 <https://github.com/pymupdf/PyMuPDF/issues/941>`_. Added old aliases for :meth:`DisplayList.get_pixmap` and :meth:`DisplayList.get_textpage`.
* **Fixed** issue `#929 <https://github.com/pymupdf/PyMuPDF/issues/929>`_. Stabilized removal of JavaScript objects with :meth:`Document.scrub`.
* **Fixed** issue `#927 <https://github.com/pymupdf/PyMuPDF/issues/927>`_. Removed a loop in the reworked :meth:`TextWriter.fill_textbox`.
* **Changed** :meth:`Document.xref_get_keys` and :meth:`Document.xref_get_key` to also allow accessing the PDF trailer dictionary. This can be done by using `-1` as the xref number argument.
* **Added** a number of functions for reconstructing the quads for text lines, spans and characters extracted by :meth:`Page.get_text` options "dict" and "rawdict". See :meth:`recover_quad` and friends.
