Bug 549520 – fr sample string
Overview of changes between 1.21.4 and 1.21.5
- Make the reference the font->fontmap reference weak. Previously all
fontmaps had circular references to their fonts and back, making them
leak instead of being freed upon finalization. Now they all clean after
themselves. There's a slight semantic change though, that a PangoFont does
not keep its fontmap alive anymore, so that's up to the user. But then
again, finalizing fontmaps is not a good idea to begin with.
- Improve pango_language_get_sample_string() to add language sample texts that
are actually usable. Compiled from a variety of sources.
See pango-language-sample-table.h.
- In pango_language_get_sample_string() use default language if provided
language is NULL.
- Update OpenType language-system tags to OpenType 1.5 draft intersected with
ISO639-3 of 2008/08/04.
- New API additions:
Add a minor new public API:
This is what pango_language_includes_script() has been using
internally. Previously one had to call that function over all
possible script values to determine which scripts a language
uses. The new API makes that much easier.
- Bugs fixed in this release:
Bug 549003 – pango_layout_set_height(): layout should not be cleared
unless required
Bug 143542 – PangoFT2Fontmap leak
Bug 314094 – Get rid of poutpourri default sample string

Bug 470895 – Improve OpenType language tag list
Bug 547432 – Deprecation of pango_(backend)_font_map_create_context()
not clean
Overview of changes between 1.21.3 and 1.21.4
- Use cairo_show_text_glyphs() if target cairo surface supports that.
This is done by adding a new PangoRenderer method, draw_glyph_item().
Custom PangoRenderer implementations that delegate to pango_cairo
may want to implement this method if they target PDF files.
- Requires cairo >= 1.7.4 now
- Win32 build improvements
- Justify lines broken by U+2028 LINE SEPARATOR
- Various small fixes and improvements
- New API additions:
New public API:
Make layout and layout-line default renderers go through
draw_glyph_item(), which then by default falls back to
draw_glyphs(). The advantage in draw_glyph_item() is that it
has access to the text and cluster information.
New public API, for iterating a PangoGlyphItem:
Make the following previously backend-only API public:
This also means that bindings are recommended to allow
instantiation of pango.Context. This was discouraged before.
New public API:
This is equivalent to pango_context_new() followed by an
immediate pango_context_set_font_map(). This change also
deprecates various per-fontmap-type context constructors:
Deprecate pango_cairo_font_map_create_context().
Deprecate pango_fc_font_map_create_context().
Deprecate pango_ft2_font_map_create_context().
Deprecate pango_win32_get_context().
Deprecate pango_xft_get_context().
Deprecate pango_x_get_context().
Language bindings are encouraged to bind
pango.Fontmap.create_context() and remove the create_context()
method from subclass implementations.

Overview of changes between 1.19.2 and 1.19.3
- pango_layout_get_pixel_extents() and pango_layout_line_get_pixel_extents()
now round extents to pixels inclusively. That is, pass both ink_rect and
logical_rect as first argument to pango_extents_to_pixels().
- Rename pango_extents_to_pixels() function arguments from @ink_rect and
@logical_rect to @inclusive and @nearest. Given that this API is a
fairly new addition and not commonly used, language bindings are
encouraged to update their argument names accordingly. Moreover, they
are encouraged to wrap this function as two different calls:
extents_to_pixels_inclusive() and extents_to_pixels_nearest(), or
similar conventions that best reflect their native language.
- HarfBuzz was relicensed to a more generous and simpler license.
Adapt. See pango/opentype/COPYING for the new license which is
- New public API:
This sets the height to which the #PangoLayout should be ellipsized at.
There are two different behaviors, based on whether @height is positive or
If @height is positive, it will be the maximum height of the layout. Only
lines would be shown that would fit, and if there is any text ommitted, an
ellipsis added. At least one line is included in each paragraph regardless
of how small the height value is. A value of zero will render exactly one
line for the entire layout.
If @height is negative, it will be the (negative of) maximum number of lines
per paragraph. That is, the total number of lines shown may well be more
than this value if the layout contains multiple paragraphs of text. The
default value of -1 means that first line of each paragraph is ellipsized.
Height setting only has effect if a positive width is set on @layout and
ellipsization mode of @layout is not %PANGO_ELLIPSIZE_NONE.
The behavior is undefined if a height other than -1 is set and ellipsization
mode is set to %PANGO_ELLIPSIZE_NONE, and may change in the future.
There are still bugs remaining to be fixed, notably bug 511172 (which will
be fixed before 1.20), and bug 511171 (which will be fixed in a future

- Update list of languages to that of fontconfig-2.4.91.
- Various optimizations, making rendering the same Pango layout using
changing cairo matrices much faster.
- Make sure all boxed type copy/free functions accept NULL as legitimate
input. Previously most were g_return_[val_]if_fail()ing it. This is
mostly for convenience when writing code in C.
- Apply 'vkrn' GPOS feature in vertical writing.
- In pangofc, set "pangoversion" in pattern passed to fontconfig,
such that font configuration can condition on being driven by Pango
or not.

aka HarfBuzz.
- Changed APIs:
* All PangoAttribute constructors are changed to initialize the
attribute to the range [0..MAXUINT]. The range was undefined
previously. All custom attribute constructors are recommended
to call the new pango_attribute_init() to do the same.
* Public API chance: Mark the following types as abstract:
PangoContext may be marked so in the future too.
* Make following macros public. Previously they were only
defined for backend/engine implementations.
- New public API:
* Convenience for initializing custom attributes:
* Adding boxed type for PangoGlyphItem:
* Add missing copy function for a boxed type in C:
* Add missing getter:
* Convenience for writing custom PangoRenderer's:
* PangoFc extensions to fontconfig's pattern syntax:

Patch from Martin Hosken
Overview of changes between 1.17.0 and 1.17.1
- Ported the rest of OpenType shapers to the new OpenType APIs and
added standard features to them: Hebrew, Indic, Khmer, Thai, and Tibetan.
- Added N'Ko support to the Arabic module. [Eugeniy Meshcheryakov]
- Small Indic module fix for Malayalam.
- Fixed font metrics returned by the ATSUI backend. [Richard Hult]
- Make itemization use pango_language_get_default() if context has no
language set on it. Ditto for pango_context_get_metrics() if both
input language and context language are NULL.
- Improved documentation on vertical text, also added stability note
to those parts of Pango API that are not indefinitely stable (shaper
and language engine APIs).
- Misc bug fixes.
- New OpenType engine API:
- Bugs fixed in this release:

Bug 438814 – synaptic crash with pango 1.17.0
Bug 440603 – Minor ABI change
Overview of changes between 1.16.4 and 1.17.0
- Text justification. A simple justification algorithm is implemented
that tries to justify by expanding spaces in the line, and if none
found, by adjust letter spacing. [Based on patch by Mathias
- The pango_script_get_sample_language() function is modified to use
the value of environment variables PANGO_LANGUAGE or LANGUAGE
(checked in that order) to make guess better languages for scripts.
The env var should be a list of language tags, like "en:fa" for
example where in effect makes Pango choose Persian (fa) fonts
instead of Arabic (ar) fonts when a run of text in the Arabic script
is found in an otherwise non-Arabic layout.
This trick is also useful for East Asian languages. For example a
Japanese user that cannot set her primary language to Japanese can
still set PANGO_LANGUAGE="ja" and Pango will map CJK characters to
The LANGUAGE env var is a standard gettext variable listing
languages the user wants to receive UI translated messages in.
However, since most packages don't provide separate English
translations, setting LANGUAGE="en:ja" doesn't have the intended
effect and UI messages will be shown in Japanese. For these
situations one can use LANGUAGE="en:C:ja". Pango skips the special
language tag 'C'.
- Simplified embedded-shape rendering with pangocairo backends do.
[Richard Hult]
- New header file: Moved PangoLanguage APIs into its own header
pango-language.h, which is included from pango-types.h.
- ATSUI backend now lists synthesized italic faces like other
- Misc optimizations and fixes.
OpenType Layout Engine Improvements:
- Vertical glyph variants are not selected in vertical text if the
font supports them.
- Instead of hardcoded OpenType script tag in each module, and using
Default Language System unconditionally, Pango will now find and use
the script/lang-sys pair that best matches the detected script and
language of a run of text. Moreover, it also applies the OpenType
'locl' feature.
These, plus the PANGO_LANGUAGE env var, give font designers and
users lots of options to provide/choose language-specific glyph
Only basic, arabic, and syriac modules updated to take advantage of
the new support so far.
New pango-view command line options:
Public API Changes:
- New public pangocairo API:
These are used by the default pangocairo renderer to render shape
attributes (see examples/cairoshape.c). Cairo-based PangoRenderer
implementations outside Pango may want to implement the draw_shape()
method similarly to provide compatibility with these new APIs. (See
bug #437533 for GdkPangoRenderer for example.)
- Other public API changes:
New is_expandable_space member in PangoLogAttr
- New OpenType engine API. These are engine API, for use by Pango
modules, and typically need not to be bound by language bindings:
- Bugs fixed in this release:
Bug 64538 – pango_layout_set_justify() doesn't work
Bug 325714 – Pango should respect $LANGUAGE
Bug 414264 – Pango vertical writing support is different with real
CJK usage.

Bug 419262 - Don't create coverage every time it's asked for
Overview of changes between 1.16.0 and 1.16.1
- Improved Win32 backend: The Win32 backend has been
updated to always require Uniscribe at compile-time (it still
is optional at run-time), and to use the wide-character variants
of Windows APIs which improves the backend in many ways. The
1.16.0 release is obsolete as far as the Win32 backend is
concerned, and official DLLs were not built for it.
- Misc build system fixes
- Bugs fixed in this release:
Bug 110521 – can't find bold and/or italic fonts on win32
Bug 120195 – there are some functions in pangowin32-fontmap.c that

- Require automake 1.9
Bugs fixed in this release:
Bug 398238 – pangorc file missing from tests directory
Overview of changes between 1.15.3 and 1.15.4
- Finish vertical text support.
- Fix various bugs that could cause ellipsization to stop prematurely.
- Fix rendering of background color being off in presence of rise attribute.
- Improved text-on-path example (examples/cairotwisted.c)
Win32 Improvements:
- Don't check for X and don't warn about missing fontconfig. [Tor Lillqvist]
- Automatically use -mms-bitfields on Windows when building with gcc. [Tor]
- Update makefile.msv. [Hans Breuer]
Code base cleanups:
- Whitespace cleanups. Hopefully patches still apply using patch -l
- Replace C++-style // comments with C-style /* */ ones.
- Move the pango-view tool from examples/ into pango-view/. The examples/
dir is still available and for simple examples only.
Public API changes:
- New PangoLayout query functions:
The is_wrapped and is_ellipsized functions return whether the layout
had to wrap/ellipsize any paragraphs, as opposed to the get_wrap and
get_ellipsize that return the wrap/ellipsize mode set.
- Misc new function:
This is more a convenience function for internal use, but set public
to go with other pango_parse_* functions. Bindings should feel free
to ignore this.
- New header files:
Moved gravity and matrix stuff into their own header files pango-gravity.h
and pango-matrix.h. Both are included from pango-types.h.
- Vertical text:
New attribute types:
New enum type:
New macro:
New public functions:
replaced by pango_gravity_get_for_matrix()
Gravity API added in previous releases:
A tip on using the vertical text support: If you just want to get correct
behavior in rotated labels (say, vertical Chinese/Japanese, but rotated
Latin, etc), all you need to do is to set the context gravity to
PANGO_GRAVITY_AUTO. You can do this for example
pango_context_set_gravity (context, PANGO_GRAVITY_AUTO);
Bugs fixed in this release:
Bug 395328 – Map kATSDeletedGlyphcode to PANGO_GLYPH_EMPTY

a value
Bug 323173 – Add layout of mixed direction text for vertical layout
Bug 394453 – Use -mms-bitfields
Bug 392628 – Don't check for X on win32
Overview of changes between 1.15.2 and 1.15.3
- Fix Hangul crasher and other Hangul bugs introduced in 1.15.2
- Spell-checked docs
- Build fixes
- Don't introduce bitfields in public structs. This changes some public API
that was broken in the 1.15 series. The new struct is backward compatible
with the older Pango series, but not with earlier 1.15.x devel releases.
- New Public API:
* PangoAnalysis.flags and PANGO_ANALYSIS_FLAGS_CENTERED_BASELINE. These are
mostly only useful for the vertical text support in Pango, but language
bindings probably want to update their bindings for PangoAnalysis to
include these.
* New PangoMatrix methods:
The transform_rectangle methods are particularly useful when an
app/toolkit wants to know the extents of a rotated layout in device
coordinates. It will be used by Gtk+ for example, and is used by the
pango-view tool too. The _pixel_ variant takes a PangoRectangle in device
units instead of Pango units.
* Unit conversion helpers:
The first two just convert between Pango units (fixed precision) and
double floating-point numbers. The current implementations are as simple
as "(int)floor (d * PANGO_SCALE + 0.5)" and "(double)i / PANGO_SCALE", but
the idea is to have optimized versions of these that do not use the FPU in
the future. That will be appreciated by embedded devices without FPU
units. Since the functionality can be generally useful, the API is made
The pango_extents_to_pixels() function in conjunction with
pango_matrix_transform_rectangle() makes it possible to convert extents to
device space and round then, instead of having to transform rounded
user-space extents.
- Bugs fixed in this release:
Bug 351496 – PangoAnalysis::gravity breaks binary compatibility
Bug 388702 – Crash when there's no Hangul glyph in the font.
Bug 384543 – FcFontMatch misuse
Bug 392789 – vpath build fails in basic module
Patch from J. Ali Harlow
Bug 390877 – Don't feed pango-features.h to glib-mkenums
Patch from Yevgen Muntyan
Overview of changes between 1.15.1 and 1.15.2
* Engines:
- Improved Hangul shaper engine
- Improved Indic shaper and language engines
- Require libthai >= 0.1.7 for the Thai language engine
* Optimizations:
- Avoid some floating-point operations. Should cut the number of float
ops per expose event in pangocairo to a half.
- Cache ink and logical extents for PangoLayout
* New Public API:
- New, generated, public header file pango-features.h. Included by
pango.h. Currently contains the version information. In the future,
can be expanded to define which backends have been enabled, etc.
- Public macros and functions for compile- and run-time version checking:
The scheme chosen here is a mixture of approaches taken by glib and cairo.
The advantage over the glib model is that there are no public variables,
but it still gives access to a string and numerical representation of the
version number at compile- and run-time.
The macros enable conditional compilation of code depending on newer Pango
APIs, while the runtime functions allow refusing to run against old
versions of the library.
- New, readonly, version of methods that give read/write access to the
internals of PangoLayout:
These should be used when you do not intend to modify the run/line,
which is most of the time the case. The only exception known to me
is Firefox that adjusts glyph widths to do justification. Most other
uses that do not write to the returned structs (or structs accessible from
them) should be ported to the new readonly API to benefit from major
optimizations (in this case, line extents caching). The list includes,
but is not limited to, Gtk+, SWT, ClassPath, gnome-applets, libgnomeprint,
xmlroff, GtkMathView, Conglomerate, Dia, Anjuta, wxWindows, The Gimp,
and various other applications/libraries:
Worth noting here is that, many uses of pango_layout_get_lines() can be
replaced by a pango_layout_get_iter() that works both more elegantly and
more efficiently. The versioning macros introduced in this release can be
used to make code use these new symbols without breaking compilation
against older Pango (though, such code compiled with the new Pango cannot
be run against an older Pango).
- pango_language_get_default(): Note that, this does not make Pango
fallback to the default language automatically (yet), but the user can
use this function to set the default language of the locale on a context:
pango_context_set_language (context, pango_language_get_default());
This essentially deprecates gtk_get_default_language(). The pango-view
tool has been updated to use this feature, so it now respects $LANG when
choosing fonts.
- pango_color_to_string().
* Bugs fixed in this release:
Bug 326099 – Setting width, indentation and ellipsizing doesn't work
as I would expect
Bug 385478 – Fix tests on OPD platform

Bug 333982 – Fallback to $LANG whenever NULL PangoLanguage is used
Patch from LingNing Zhang
Overview of changes between 1.15.0 and 1.15.1
* Add Thai langauage engine. (currently makes tests/testboundary fail.)
* Add Lao and improved Thai sample text.
* Improved Indic module.
* Output correct path for hexboxes in pango_cairo_layout_path().
* Implement get_resolution method for the FT2 fontmap. Shouldn't make
any difference whatsoever. Open a bug if it does.
* Misc small fixes.
* Optimizations:
- Rework PangoLayout algorithms to avoid calling a recursive call to
pango_layout_get_extents(). Avoids one pango_font_get_glyph_extents()
call per glyph per layout rendering. We now make 2 such calls.
- Don't cache run_logical_rect in PangoLayoutIter.
Avoids one pango_font_get_glyph_extents() call per glyph per layout
rendering. We are down to 1 now.
- Cache line extents. This avoids the final pango_font_get_glyph_extents()
call per glyph per layout rendering. Now we don't make any
pango_font_get_glyph_extents() calls when rendering a layout (some
conditions apply)!
internal uses, that is, just a NULL-check.
- Use simple, fast, casts instead of PANGO_CAIRO_*() macros where the
object cannot have reached us if it wasn't of the right type.
