- Update to v1.20.2
* This release uses MuPDF-1.20.3
* Fix linking issues on Unix systems.
* Fixed SegFault when applying redactions overlapping a transparent image.
* Improvements to documentation
* Removed some unused files and directories
- from v1.20.1
* Fix for building on FreeBSD.
* Fixed linkDest() had a broken call to re.match(), introduced in 1.20.0.
* Fixed get_drawings() and get_cdrawings() previously always returned
with closePath=False.
* Default FreeText annotation text color is now black.
* Improvements to sphinx-generated documentation
- from v1.20.0
* This release uses MuPDF-1.20.0
* Cope with new MuPDF link uri format, changed from #<int>,<int>,<int>
to #page=<int>&zoom=<float>,<float>,<float>.
* In tests/test_insertpdf.py, use new reference output joined-1.20.pdf.
We also check that new output values are approximately the same as the old ones.
* Fixed Leak of pdf_graft_map. Also fixed a SEGV issue that this seemed
to expose, caused by incorrect freeing of underlying fz_document.
* Fixed ownership of Annotation.get_pixmap().
* If pip builds from source because an appropriate wheel is not available,
we no longer require MuPDF to be pre-installed. Instead the required
MuPDF source is embedded in the sdist and automatically built into PyMuPDF.
* Various changes to setup.py to download the required MuPDF release
as required. See comments at start of setup.py for details.
* Tue May 10 2022 Matej Cepl <mcepl@suse.com>
- Clean up SPEC file.
- Switch to pip/wheel-based build.
* Sun Mar 06 2022 Hsiu-Ming Chang <cges30901@gmail.com>
- 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.
* Sun Feb 06 2022 Hsiu-Ming Chang <cges30901@gmail.com>
- 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.
* Mon Jan 10 2022 Hsiu-Ming Chang <cges30901@gmail.com>
- 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).
* Fri Dec 17 2021 Hsiu-Ming Chang <cges30901@gmail.com>
- 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).
* Mon Nov 22 2021 Hsiu-Ming Chang <cges30901@gmail.com>
- 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.
* Sat Apr 10 2021 John Vandenberg <jayvdb@gmail.com>
- Update to v1.18.11
* Improved layout of source distribution material.
* Stabilized Linux distribution detection for generating PyMuPDF
from sources.
* Page.get_xobjects delivers the result of Document.get_page_xobjects.
* Page.get_image_info delivers meta information for all images shown
on the page.
* Tools.mupdf_display_warnings allows setting on / off the display
of MuPDF-generated warnings. The default is off.
* Document.ez_save convenience alias of :meth:`Document.save`
with some different defaults.
* 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).
* Sat Feb 27 2021 John Vandenberg <jayvdb@gmail.com>
- Revised License to be AGPL-3.0-only
- Add %doc
- Remove COPYING now provided in tarball
- Update to v1.18.9
* Removed ambiguous statements concerning PyMuPDF's license,
which is now clearly stated to be GNU AGPL V3
* Fixed issue 895
* Since v1.17.6 PyMuPDF suppresses the font subset tags and only
reports the base fontname in text extraction outputs
"dict" / "json" / "rawdict" / "rawjson".
Now a new global parameter can request the old behaviour,
`Tools.set_subset_fontnames`.
* Pixmap creation now also works with filenames given as pathlib.
* Changed `Document.subset_fonts`: Text is not rewritten any more
and should therefore retain all its origial properties -- like
being hidden or being controlled by Optional Content mechanisms.
* `TextWriter.fill_textbox`, `TextWriter.append` now accept a new
boolean parameter `right_to_left`, which is *False* by default.
* Changed `TextWriter.fill_textbox` to return all lines of text,
that did not fit in the given rectangle. Also changed the default
of the `warn` parameter to no longer print a warning message
in overflow situations.
* Added a utility function `recover_quad`, which computes the
quadrilateral of a span. This function can be used when
quadrilaterals for text extracted with the "dict" or "rawdict"
options of `Page.get_text`.
* Mon Feb 08 2021 John Vandenberg <jayvdb@gmail.com>

* Fixed a memory leak in Page.insert_image when inserting
images from files or memory
* pathlib.Path objects should now correctly handle file path
hierarchies
- from v1.18.7
* Added an experimental Document.subset_fonts which reduces
the size of eligible fonts based on their use by text in the PDF
* Document.convert_to_pdf now also supports PDF documents
* Renamed Document.write to Document.tobytes for greater clarity.
But the deprecated name remains available for some time.
* Document.tobytes` now supports linearized PDF output
* Document.save` now also supports writing to Python file objects.
In addition, the open function now supports Python file objects.

label definitions of a PDF.
* Added :meth:`Document.has_annots and Document.has_links to check
whether these object types are present anywhere in a PDF.
* Added expert low-level functions to simplify inquiry and
modification of PDF object sources:
+ Document.xref_get_keys lists the keys of object `xref`
+ Document.xref_get_key returns type and content of a key
+ Document.xref_set_key modifies the key's value
* Added parameter thumbnails to Document.scrub to also allow
removing page thumbnail images
* Improved documentation for how to add valid text marker
annotations for non-horizontal text
- from v1.18.6
* Introduced Python type hinting
* Fixed issue #812.
* Invalid document metadata previously prevented opening some
documents at all. This error has been removed.
* Text search and text extraction will make no rectangle
containment checks at all if the default clip=None is used.
* Fixed issue #785.
* Corrected a parameter check error.
* Added an option to set the desired line height for text boxes
* Changed text position retrieval to better cope with Tesseract's
glyphless font.
* Added an option to choose the prefix of new annotations,
fields and links for providing unique annotation ids
* Added getting and setting color and text properties for
Table of Contents items for PDFs
* Added PDF page label handling: Page.get_label() returns the
page label, Document.get_page_numbers return all page numbers
having a specified label, and Document.set_page_labels adds
or updates a PDF's page label definition.
- from v1.18.5
* Apart from several fixes, this version also focusses on several
minor, but important feature improvements.
Among the latter is a more precise computation of proper line
heights and insertion points for writing / inserting text.
As opposed to using font-agnostic constants, these values are
now taken from the font's properties.
* By using "small glyph heights" option, the full page text can
be extracted.
* Fixed issue #768.
* Fixed issue #750.
* The "dict", "rawdict" and corresponding JSON output variants
now have two new span keys: "ascender" and "descender".
These floats represent special font properties which can be
used to compute bboxes of spans or characters of exactly
fontsize height (as opposed to the default line height).
An example algorithm is shown in section "Span Dictionary"
here. Also improved the detection and correction of
ill-specified ascender / descender values encountered
in some fonts.
* Added a new, experimental Tools.set_small_glyph_heights. This
method sets or unsets a global parameter to always compute
bboxes with fontsize height. If "on", text searching and all
text extractions will returned rectangles, bboxes and quads
with a smaller height.
* Fixed issue #728.
* Changed fill color logic of 'Polyline' annotations: this
parameter now only pertains to line end symbols --
the annotation itself can no longer have a fill color
* Changed Page.getImageBbox to also compute the bbox if the image
is contained in an XObject.
* Changed Shape.insertTextbox, resp. Page.insertTextbox, resp.
TextWriter.fillTextbox to respect font's properties "ascender" /
"descender" when computing line height and insertion point.
This should no longer lead to line overlaps for multi-line output.
These methods used to ignore font specifics and used constant
values instead.
- from v1.18.4
* Adds several features to support PDF Optional Content, including
OCMDs (Optional Content Membership Dictionaries) with the full
scope of "visibility expressions" (PDF key /VE), text insertions
(including the TextWriter class) and drawings.
* Freetext annotations now support an uncolored rectangle when
fill_color=None.
* UTF-8 encoding errors are now handled for HTML / XML Page.getText.
* Empty values are no longer stored in the PDF /Info metadata
dictionary.
* Added new methods Document.set_oc and Document.get_oc to set or
get optional content references for existing image and form
XObjects. These methods are similar to the same-named methods
of Annot.
* Added Document.set_ocmd, Document.get_ocmd for handling OCMDs.
* Added Optional Content support for text insertion and drawing.
* Added new method Page.deleteWidget, which deletes a form field
from a page. This is analogous to deleting annotations.
* Added support for Popup annotations. This includes defining
the Popup rectangle and setting the Popup to open or closed.
Methods / attributes Annot.set_popup, Annot.set_open,
Annot.has_popup, Annot.is_open, Annot.popup_rect, Annot.popup_xref
* Annot methods and attributes converted to lower case with
underscores, while keeping UPPERCASE for the constants.
Old names will remain available to prevent code breaks, but they
will no longer be mentioned in the documentation.
- from v1.18.3
* Introduces support for PDF's Optional Content concept.
This includes several new Document methods for inquiring and setting
optional content status and adding optional content
configurations and groups. In addition, images, form XObjects
and annotations now can be bound to optional content specifications.
* Fixed issue #714.
* Fixed issue #711.
* If a PDF user password, but no owner password is supplied nor
present, then the user password is also used as the owner password.
* Fixed expand and deflate parameters of methodsDocument.save
and Document.write. Individual image and font compression should
now finally work.
- from v1.18.2
* Contains some interesting improvements for text searching: any
number of search hits is now returned and the hit_max parameter
was removed. The new clip parameter in addition allows to restrict
the search area. Searching now detects hyphenations at line breaks
and accordingly finds hyphenated words.
* If using quads=False in text searching, then overlapping rectangles
on the same line are joined. Previously, parts of the search string,
which belonged to different "marked content" items, each generated
their own rectangle -- just as if occurring on separate lines.
* Added Document.isRepaired, which is true if the PDF was
repaired on open.
* Added Document.setXmlMetadata which either updates or creates
PDF XML metadata
* Added Document.getXmlMetadata returns PDF XML metadata.
* Changed creation of PDF documents: they will now always carry a
PDF identification (/ID field) in the document trailer
* Changed Page.searchFor: a new parameter clip is accepted to
restrict the search to this rectangle. Correspondingly, the
attribute TextPage.rect is now respected by TextPage.search.
* Changed parameter hit_max in Page.searchFor and TextPage.search
is now obsolete: methods will return all hits.
* Changed character selection criteria in Page.getText: a character
is now considered to be part of a clip if its bbox is fully
contained. Before this, a non-empty intersection was sufficient.
* Changed Document.scrub to support a new option redact_images.
- from v1.18.1
* Detects and recovers from more cyclic resource dependencies
in PDF pages and for the first time reports them in the
MuPDF warnings store.
* Fixed issue #686.
* Added opacity options for the Shape class: Stroke and fill
colors can now be set to some transparency value.
This means that all Page draw methods, methods
Page.insertText, Page.insertTextbox, Shape.finish,
Shape.insertText, and Shape.insertTextbox support two
new parameters: stroke_opacity and fill_opacity.
* Added new parameter mask to Page.insertImage for
optionally providing an external image mask
* Added Annot.soundGet for extracting the sound of an audio
annotation.
- from v1.18.0
* Supports MuPDF v1.18
* An upstream bug occurred occasionally for some pages only
and seems to be fixed now: page layout should no longer
be ruined in these cases.
* Unsuccessful storage allocations should now always lead to
exceptions (circumvention of an upstream bug intermittently
crashing the interpreter).
* Pixmap size is now based on size_t instead of int in C and
should be correct even for extremely large pixmaps
* Specification of dashes for PDF drawing insertion should now
correctly reflect the PDF spec
* A memory leakage in Page.insert_pdf has been removed
* Added keyword "images" to Page.apply_redactions for
fine-controlling the handling of images
* Added Annot.getText and Annot.getTextbox, which offer
the same functionality as the Page versions
* Added key "number" to the block dictionaries of Page.getText /
Annot.getText for options "dict" and "rawdict"
* Added glyph_name_to_unicode and unicode_to_glyph_name.
Both functions do not really connect to a specific font and
are now independently available, too.
The data are now based on the Adobe Glyph List.
* Added convenience functions adobe_glyph_names and
adobe_glyph_unicodes which return the respective available data
* Added Page.getDrawings which returns details of drawing
operations on a document page. Works for all document types
* Improved performance of Document.insert_pdf.
Multiple object copies are now also suppressed across multiple
separate insertions from the same source. This saves time,
memory and target file size. Previously this mechanism was only
active within each single method execution. The feature can also
be suppressed with the new method bool parameter final=1,
which is the default.
* For PNG images created from pixmaps, the resolution (dpi) is
now automatically set from the respective Pixmap.xres and
Pixmap.yres values
