- Update to v1.19.6
* Fixed #1620. The TextPage created by Page.get_textpage() will
now be freed correctly (removed memory leak).
* Fixed #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 Document
(fitz.open()) from an empty file or zero-length memory.
FileDataError – raised when MuPDF encounters irrecoverable
document structure issues.
* Added Page.load_widget() given a PDF field’s xref.
* Added Dictionary 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 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
TEXTFLAGS_WORDS for page.get_text("words"). See Text Extraction
Flags Defaults.
* Changed Page.annots() and Page.widgets() to detect and prevent
reloading the page (illegally) inside the iterator loops via
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 Tools
class. This, among other things, increases the performance of
geometry object creation.
* Changed 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.

- Update to v1.19.5
* Fixed #1518. A limited “fix”: in some cases, rectangles and
quadrupels were not correctly encoded to support re-drawing by
Shape.
* Fixed #1521. This had the same ultimate reason behind issue
#1510.
* Fixed #1513. Some Optional Content functions did not support
non-ASCII characters.
* Fixed #1510. Support more soft-mask image subtypes.
* Fixed #1507. Immunize against items in the outlines chain,
that are "null" objects.
* Fixed re-opened #1417. (“too many open files”). This was due
to insufficient calls to MuPDF’s fz_drop_document(). This also
fixes #1550.
* Fixed several undocumented issues in relation to incorrectly
setting the text span origin point_like.
* Fixed undocumented error computing the character bbox in
method Page.get_texttrace() when text is flipped (as opposed to
just rotated).
* Added items to the dictionary returned by image_properties():
orientation and transform report the natural image orientation
(EXIF data).
* Added method Document.xref_copy(). It will make a given target
PDF object an exact copy of a source object.

- Update to v1.19.4
* Fixed #1505. Immunize against circular outline items.
* Fixed #1484. Correct CropBox coordinates are now returned in
all situations.
* Fixed #1479.
* Fixed #1474. TextPage objects are now properly deleted again.
* Added Page methods and attributes for PDF /ArtBox, /BleedBox,
/TrimBox.
* Added global attribute TESSDATA_PREFIX for easy checking of OCR
support.
* Changed Document.xref_set_key() such that dictionary keys will
physically be removed if set to value "null".
* Changed Document.extract_font() to optionally return a
dictionary (instead of a tuple).

- Update to v1.19.3
* Fixed #1351. Reverted code that introduced the memory growth
in v1.18.15.
* Fixed #1417. Developped circumvention for growth of open file
handles using Document.insert_pdf().
* Fixed #1418. Developped circumvention for memory growth using
Document.insert_pdf().
* Fixed #1430. Developped circumvention for mass pixmap
generations of document pages.
* Fixed #1433. Solves a bbox error for some Type 3 font in
PyMuPDF text processing.
* Added Pixmap.color_topusage() to determine the share of the
most frequently used color. Solves #1397.
* Added Pixmap.warp() which makes a new pixmap from a given
arbitrary convex quad inside the pixmap.
* Added Annot.irt_xref and Annot.set_irt_xref() to inquire or
set the /IRT (“In Responde To”) property of an annotation.
Implements #1450.
* Added Rect.torect() and IRect.torect() which compute a matrix
that transforms to a given other rectangle.
* Changed Pixmap.color_count() to also return the count of each
color.
* Changed Page.get_texttrace() to also return correct span and
character bboxes if span["dir"] != (1, 0).

- Update to v1.19.2
* Fixed #1388. Fixed intermittent memory corruption when insert or
updating annotations.
* Fixed #1375. Inconsistencies between line numbers as returned
by the “words” and the “dict” options of `Page.get_text()` have
been corrected.
* Fixed #1364. The check for being a "rawdict" span in
`recover_span_quad()` now works correctly.
* Fixed #1342. Corrected the check for rectangle infiniteness in
`Page.show_pdf_page()`.
* Changed `Page.get_drawings()`, `Page.get_cdrawings()` to return
an indicator on the area orientation covered by a rectangle. This
implements #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 `Page.get_pixmap()` and
`Annot.get_pixmap()`. When given, parameter "matrix" is ignored,
and a Pixmap with the desired dots per inch is created.
* Added attributes `Pixmap.is_monochrome` and `Pixmap.is_unicolor`
allowing fast checks of pixmap properties. Addresses #1397.
* Added method `Pixmap.color_count()` to determine the unique
colors in the pixmap.
* Added boolean parameter "compress" to PDF document method
`Document.update_stream()`. Addresses / enables solution for
#1408.
- from v1.19.1
* Fixed #1328. “words” text extraction again returns correct (x0,
y0) coordinates.
* Changed `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 `Page.get_drawings()` and `Page.get_cdrawings()` to
automatically convert colors to RGB color tuples. Implements
#1332. Similar change was applied to `Page.get_texttrace()`.
* Changed `Page.get_text()` to support a parameter sort. If set
to True the output is conveniently sorted.
- from v1.19.0
* Supports MuPDF 1.19.*
* 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 Rect section for details.
* Added new parameter “no_new_id” to `Document.save()` /
`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 `Document.journal_enable()` and friends.
* Added new Pixmap methods `Pixmap.pdfocr_save()` and
`Pixmap.pdfocr_tobytes()`, which generate a 1-page PDF containing
the pixmap as PNG image with OCR text layer.
* Added `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 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 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 `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 `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 `Page.get_drawings()` and
`Page.get_cdrawings()` to include a “sequence number” indicating
the page appearance build operation that created the drawing.
* Fixed #1311. Field values in comboboxes should now be handled
correctly.
* Fixed #1290. Error was caused by incorrect rectangle emptiness
check, which is fixed due to new geometry logic of this version.
* Fixed #1286. Text alignment for redact annotations is working
again.
* Fixed #1287. Infinite loop issue for non-Windows systems when
applying some redactions has been resolved.
* Fixed #1284. Text layout destruction after applying redactions in
some cases has been resolved.
- from v1.18.19
* Fixed issue #1266. Failure to set `Pixmap.samples` in important
cases, was hotfixed in a new version 1.18.19.
- from v1.18.18
* Fixed issue #1257. Removing the read-only flag from PDF fields
is now possible.
* Fixed issue #1252. Now correctly specifying the zoom value for
PDF link annotations.
* Fixed issue #1244. Now correctly computing the transform matrix
in `Page.get_image__bbox()`.
* Fixed issue #1241. Prevent returning artifact characters in
`Page.get_textbox()`, which happened in certain constellations.
* Fixed issue #1234. Avoid creating infinite rectangles in corner
cases – `Page.get_drawings()`, `Page.get_cdrawings()`.
* Added test data and test scripts to the source PyPI source
distribution.
- from v1.18.17
* Fixed issue #1199. Using a non-existing page number in
`Document.get_page_images()` and friends will no longer lead to
segfaults.
* Changed `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 `Page.get_cdrawings()`, performance-optimized version of
`Page.get_drawings()`.
* Added `Pixmap.samples_mv`, memoryview of a pixmap’s pixel area.
Does not copy and thus always accesses the current state of that
area.
* Added `Pixmap.samples_ptr`, Python “pointer” to a pixmap’s pixel
area. Allows much faster creation (factor 800+) of Qt images.
- from v1.18.16
* Fixed issue #1184. Existing PDF widget fonts in a PDF are now
accepted (i.e. not forcedly changed to a Base-14 font).
* Fixed issue #1154. Text search hits should now be correct when
clip is specified.
* Fixed issue #1152.
* Fixed issue #1146.
* Added `Link.flags` and `Link.set_flags()` to the Link class.
Implements enhancement requests #1187.
* Added option to simulate `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.
- from v1.18.15
* Fixed issue #1088. Removing an annotation’s fill color should now
work again both ways, using the fill_color=[] argument in
`Annot.update()` as well as fill=[] in `Annot.set_colors()`.
* Fixed issue #1081. `Document.subset_fonts()`: fixed an error
which created wrong character widths for some fonts.
* Fixed issue #1078. `Page.get_text()` and other methods related to
text extraction: changed the default value of the TextPage flags
parameter. All whitespace and ligatures are now preserved.
* Fixed issue #1085. The old snake_cased alias of
`fitz.detTextlength` is now defined correctly.
* Changed `Document.subset_fonts()` will now correctly prefix font
subsets with an appropriate six letter uppercase tag, complying
with the PDF specification.
* Added new method `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 Font and
TextWriter classes. This is reflected by an additional bool
parameter small_caps in various of their methods.
- from v1.18.14
* 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 Deprecated
Names with more background and a mapping of old to new names.
* Fixed issue #1053. `Page.insert_image()`: when given, include
image mask in the hash computation.
* Fixed issue #1043. Added `Pixmap.getPNGdata` to the aliases of
`Pixmap.tobytes()`.
* Fixed an internal error when computing the envelopping
rectangle of drawn paths as returned by `Page.get_drawings()`.
* Fixed an internal error occasionally causing loops when
outputting text via `TextWriter.fill_textbox()`.
* Added `Font.char_lengths()`, which returns a tuple of character
widths of a string.
* Added more ways to specify pages in `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 `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.
- from v1.18.13
* Fixed issue #1014
* Fixed an internal memory leak when computing image bboxes –
`Page.get_image_bbox()`.
* Added support for low-level access and modification of the PDF
trailer. Applies to `Document.xref_get_keys()`,
`Document.xref_get_key(), and Document.xref_set_key()`.
* Added documentation for maintaining private entries in PDF
metadata.
* Added documentation for handling transparent image insertions,
`Page.insert_image()`.
* Added `Page.get_image_rects()`, an improved version of
`Page.get_image_bbox()`.
* Changed `Document.delete_pages()` to support various ways of
specifying pages to delete.
* Changed `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 `Page.insert_image()` to also accept the integer
parameter alpha. To be used for performance improvements.
* Changed `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 `Document.embfile_add()` to automatically set creation
and modification date-time. Correspondingly,
`Document.embfile_upd()` automatically maintains modification
date-time (/ModDate PDF key), and `Document.embfile_info()`
correspondingly reports these data. In addition, the embedded
file’s associated “collection item” is included via its xref.
This supports the development of PDF portfolio applications.

* Image extractions of document pages now also contain the image's
**transformation matrix**. This concerns `Page.get_image_bbox`
and the DICT, JSON, RAWDICT, and RAWJSON variants of `Page.get_text`.
- from v1.18.10
* Added old aliases for `DisplayList.get_pixmap` and
`DisplayList.get_textpage`.
* Stabilized removal of JavaScript objects with `Document.scrub`.
* Removed a loop in the reworked `TextWriter.fill_textbox`.
* `Document.xref_get_keys` and `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 `Page.get_text` options
"dict" and "rawdict".
* Added `Tools.unset_quad_corrections` to suppress character quad
corrections (occasionally required for erroneous fonts).
