<enum name="PangoAlignment">
<description>
`PangoAlignment` describes how to align the lines of a `PangoLayout`
within the available space.

If the `PangoLayout` is set to justify using [method@Pango.Layout.set_justify],
this only has effect for partial lines.

See [method@Pango.Layout.set_auto_dir] for how text direction affects
the interpretation of `PangoAlignment values.

<enum name="PangoAttrType">
<description>
The `PangoAttrType` distinguishes between different types of attributes.

Along with the predefined values, it is possible to allocate additional
values for custom attributes using [func@AttrType.register]. The predefined
values are given below. The type of structure used to store the attribute is
listed in parentheses after the description.

<enum name="PangoDirection">
<description>
`PangoDirection` represents a direction in the Unicode bidirectional
algorithm.

Not every value in this enumeration makes sense for every usage of
`PangoDirection`; for example, the return value of [func@unichar_direction]
and [func@find_base_dir] cannot be %PANGO_DIRECTION_WEAK_LTR or
%PANGO_DIRECTION_WEAK_RTL, since every character is either neutral
or has a strong direction; on the other hand %PANGO_DIRECTION_NEUTRAL
doesn't make sense to pass to [func@itemize_with_base_dir].

The %PANGO_DIRECTION_TTB_LTR, %PANGO_DIRECTION_TTB_RTL values come from
an earlier interpretation of this enumeration as the writing direction
of a block of text and are no longer used; See `PangoGravity` for how
vertical text is handled in Pango.

If you are interested in text direction, you should really use fribidi
directly. `PangoDirection` is only retained because it is used in some
public apis.

<enum name="PangoGravity">
<description>
`PangoGravity` represents the orientation of glyphs in a segment
of text.

This is useful when rendering vertical text layouts. In those situations,
the layout is rotated using a non-identity [struct@Pango.Matrix], and then
glyph orientation is controlled using `PangoGravity`.

Not every value in this enumeration makes sense for every usage of
`PangoGravity`; for example, %PANGO_GRAVITY_AUTO only can be passed to
[method@Pango.Context.set_base_gravity] and can only be returned by
[method@Pango.Context.get_base_gravity].

<function name="pango_cairo_font_map_set_default">
<description>
Sets a default `PangoCairoFontMap` to use with Cairo.

This can be used to change the Cairo font backend that the
default fontmap uses for example. The old default font map
is unreffed and the new font map referenced.

Note that since Pango 1.32.6, the default fontmap is per-thread.
This function only changes the default fontmap for
the current thread. Default fontmaps of existing threads
are not changed. Default fontmaps of any new threads will
still be created using [func@PangoCairo.FontMap.new].

A value of %NULL for @fontmap will cause the current default
font map to be released and a new default font map to be created
on demand, using [func@PangoCairo.FontMap.new].

includes the original rectangle.

The @nearest rectangle is converted by rounding the coordinates
of the rectangle to the nearest device unit (pixel).

The rule to which argument to use is: if you want the resulting device-space
rectangle to completely contain the original rectangle, pass it in as
@inclusive. If you want two touching-but-not-overlapping rectangles stay
touching-but-not-overlapping after rounding to device units, pass them in
as @nearest.

<function name="pango_find_paragraph_boundary">
<description>
Locates a paragraph boundary in @text.

A boundary is caused by delimiter characters, such as
a newline, carriage return, carriage return-newline pair,

The index of the run of delimiters is returned in
@paragraph_delimiter_index. The index of the start
of the paragrap (index after all delimiters) is stored
in @next_paragraph_start.

If no delimiters are found, both @paragraph_delimiter_index

Creates a new font description from a string representation.

The string must have the form

&quot;\[FAMILY-LIST] \[STYLE-OPTIONS] \[SIZE] \[VARIATIONS]&quot;,

where FAMILY-LIST is a comma-separated list of families optionally
terminated by a comma, STYLE_OPTIONS is a whitespace-separated list
of words where each word describes one of style, variant, weight,
stretch, or gravity, and SIZE is a decimal number (size in points)
or optionally followed by the unit modifier &quot;px&quot; for absolute size.
VARIATIONS is a comma-separated list of font variation
specifications of the form &quot;\@axis=value&quot; (the = sign is optional).

The following words are understood as styles:
&quot;Normal&quot;, &quot;Roman&quot;, &quot;Oblique&quot;, &quot;Italic&quot;.

The following words are understood as variants:
&quot;Small-Caps&quot;, &quot;All-Small-Caps&quot;, &quot;Petite-Caps&quot;, &quot;All-Petite-Caps&quot;,
&quot;Unicase&quot;, &quot;Title-Caps&quot;.

The following words are understood as weights:
&quot;Thin&quot;, &quot;Ultra-Light&quot;, &quot;Extra-Light&quot;, &quot;Light&quot;, &quot;Semi-Light&quot;,
&quot;Demi-Light&quot;, &quot;Book&quot;, &quot;Regular&quot;, &quot;Medium&quot;, &quot;Semi-Bold&quot;, &quot;Demi-Bold&quot;,

&quot;Semi-Expanded&quot;, &quot;Expanded&quot;, &quot;Extra-Expanded&quot;, &quot;Ultra-Expanded&quot;.

The following words are understood as gravity values:
&quot;Not-Rotated&quot;, &quot;South&quot;, &quot;Upside-Down&quot;, &quot;North&quot;, &quot;Rotated-Left&quot;,
&quot;East&quot;, &quot;Rotated-Right&quot;, &quot;West&quot;.

Any one of the options may be absent. If FAMILY-LIST is absent, then
the family_name field of the resulting font description will be
initialized to %NULL. If STYLE-OPTIONS is missing, then all style
options will be set to the default values. If SIZE is missing, the
size in the resulting font description will be set to 0.

<description>
A monospace font is a font designed for text display where the the
characters form a regular grid.

For Western languages this would
mean that the advance width of all characters are the same, but
this categorization also includes Asian fonts which include
double-width characters: characters that occupy two grid cells.
g_unichar_iswide() returns a result that indicates whether a
character is typically double-width in a monospace font.

The best way to find out the grid-cell size is to call
[method@Pango.FontMetrics.get_approximate_digit_width], since the
results of [method@Pango.FontMetrics.get_approximate_char_width] may
be affected by double-width characters.

<function name="pango_glyph_item_apply_attrs">
<description>
Splits a shaped item (`PangoGlyphItem`) into multiple items based
on an attribute list.

The idea is that if you have attributes that don't affect shaping,
such as color or underline, to avoid affecting shaping, you filter
them out ([method@Pango.AttrList.filter]), apply the shaping process
and then reapply them to the result using this function.

All attributes that start or end inside a cluster are applied
to that cluster; for instance, if half of a cluster is underlined
and the other-half strikethrough, then the cluster will end
up with both underline and strikethrough attributes. In these
cases, it may happen that @item-&gt;extra_attrs for some of the
result items can have multiple attributes of the same type.

This function takes ownership of @glyph_item; it will be reused
as one of the elements in the list.

Convert a language tag to a `PangoLanguage`.

This function first canonicalizes the string by converting it to

<function name="pango_language_get_default">
<description>
Returns the `PangoLanguage` for the current locale of the process.

On Unix systems, this is the return value is derived from
`setlocale (LC_CTYPE, NULL)`, and the user can
affect this through the environment variables LC_ALL, LC_CTYPE or
LANG (checked in that order). The locale string typically is in
the form lang_COUNTRY, where lang is an ISO-639 language code, and
COUNTRY is an ISO-3166 country code. For instance, sv_FI for
Swedish as written in Finland or pt_BR for Portuguese as written in
Brazil.

On Windows, the C library does not use any such environment
variables, and setting them won't affect the behavior of functions
like ctime(). The user sets the locale through the Regional Options
in the Control Panel. The C library (in the setlocale() function)
does not use country and language codes, but country and language
names spelled out in English.
However, this function does check the above environment
variables, and does return a Unix-style locale string based on
either said environment variables or the thread's current locale.

Your application should call `setlocale(LC_ALL, &quot;&quot;)` for the user
settings to take effect. GTK does this in its initialization
functions automatically (by calling gtk_set_locale()).
See the setlocale() manpage for more details.

Note that the default language can change over the life of an application.

Also note that this function will not do the right thing if you
use per-thread locales with uselocale(). In that case, you should
just call pango_language_from_string() yourself.

When choosing language-specific resources, such as the sample

font feature requirements unique to the language. It is suitable for use

<description>
Determines the scripts used to to write @language.

If nothing is known about the language tag @language,
or if @language is %NULL, then %NULL is returned.
The list of scripts returned starts with the script that the
language uses most and continues to the one it uses least.

The value @num_script points at will be set to the number
of scripts in the returned array (or zero if %NULL is returned).

Most languages use only one script for writing, but there are
some that use two (Latin and Cyrillic for example), and a few
use three (Japanese for example). Applications should not make
any assumptions on the maximum number of scripts returned
though, except that it is positive if the return value is not
%NULL, and it is a small number.

The [method@Pango.Language.includes_script] function uses this
function internally.

Note: while the return value is declared as `PangoScript`, the
returned values are from the `GUnicodeScript` enumeration, which
may have more values. Callers need to handle unknown values.

This routine is used in Pango's itemization process when

<function name="pango_layout_get_cursor_pos">
<description>
Given an index within a layout, determines the positions that of the
strong and weak cursors if the insertion point is at that index.

The position of each cursor is stored as a zero-width rectangle
with the height of the run extents.

&lt;picture&gt;
&lt;source srcset=&quot;cursor-positions-dark.png&quot; media=&quot;(prefers-color-scheme: dark)&quot;&gt;
&lt;img alt=&quot;Cursor positions&quot; src=&quot;cursor-positions-light.png&quot;&gt;
&lt;/picture&gt;

The strong cursor location is the location where characters of the
directionality equal to the base direction of the layout are inserted.
The weak cursor location is the location where characters of the
directionality opposite to the base direction of the layout are inserted.

The following example shows text with both a strong and a weak cursor.

&lt;picture&gt;
&lt;source srcset=&quot;split-cursor-dark.png&quot; media=&quot;(prefers-color-scheme: dark)&quot;&gt;
&lt;img alt=&quot;Strong and weak cursors&quot; src=&quot;split-cursor-light.png&quot;&gt;
&lt;/picture&gt;

The strong cursor has a little arrow pointing to the right, the weak
cursor to the left. Typing a 'c' in this situation will insert the
character after the 'b', and typing another Hebrew character, like 'ג',
will insert it at the end.

In the presence of bidirectional text, the correspondence between
logical and visual order will depend on the direction of the current
run, and there may be jumps when the cursor is moved off of the end

Motion here is in cursor positions, not in characters, so a single

<function name="pango_layout_set_height">
<description>
Sets the height to which the `PangoLayout` should be ellipsized at.

There are two different behaviors, based on whether @height is positive
or negative.

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 omitted,
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 the first line of each paragraph is ellipsized.
This behavior may be changed in the future to act per layout instead of per
paragraph. File a bug against pango at
[https://gitlab.gnome.org/gnome/pango](https://gitlab.gnome.org/gnome/pango)
if your code relies on this behavior.

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.

<function name="pango_layout_set_markup_with_accel">
<description>
Sets the layout text and attribute list from marked-up text.

See [Pango Markup](pango_markup.html)).

Replaces the current text and attribute list.

If @accel_marker is nonzero, the given character will mark the
character following it as an accelerator. For example, @accel_marker
might be an ampersand or underscore. All characters marked
as an accelerator will receive a %PANGO_UNDERLINE_LOW attribute,
and the first character so marked will be returned in @accel_char.
Two @accel_marker characters following each other produce a single
literal @accel_marker character.

The default value is 0.

Note: Since 1.44, Pango is using the line height (as determined
by the font) for placing lines when the line spacing factor is set
to a non-zero value with [method@Pango.Layout.set_line_spacing].
In that case, the @spacing set with this function is ignored.

By default, tabs are every 8 spaces. If @tabs is %NULL, the
default tabs are reinstated. @tabs is copied into the layout;
you must free your copy of @tabs yourself.

Note that tabs and justification conflict with each other:
Justification will move content away from its tab-aligned
positions. The same is true for alignments other than
%PANGO_ALIGN_LEFT.

<description>
Incrementally parses marked-up text to create a plain-text string

See the [Pango Markup](pango_markup.html) docs for details about the
supported markup.

If @accel_marker is nonzero, the given character will mark the
character following it as an accelerator. For example, @accel_marker
might be an ampersand or underscore. All characters marked
as an accelerator will receive a %PANGO_UNDERLINE_LOW attribute,
and the first character so marked will be returned in @accel_char,
when calling [func@markup_parser_finish]. Two @accel_marker characters
following each other produce a single literal @accel_marker character.

To feed markup to the parser, use g_markup_parse_context_parse()
on the returned `GMarkupParseContext`. When done with feeding markup
to the parser, use [func@markup_parser_finish] to get the data out
of it, and then use g_markup_parse_context_free() to free it.

Affine transformations are position invariant, so the same vector
always transforms to the same vector. If (@x1,@y1) transforms
to (@x2,@y2) then (@x1+@dx1,@y1+@dy1) will transform to
(@x1+@dx2,@y1+@dy2) for all values of @x1 and @x2.

<description>
Finds the index of a feature.

If the feature is not found, sets @feature_index to PANGO_OT_NO_FEATURE,
which is safe to pass to [method@PangoOT.Ruleset.add_feature] and similar
functions.

In the future, this may set @feature_index to an special value that if
used in [method@PangoOT.Ruleset.add_feature] will ask Pango to synthesize
the requested feature based on Unicode properties and data. However, this
function will still return %FALSE in those cases. So, users may want to
ignore the return value of this function in certain cases.

Finds the index of a language and its required feature index.

If the language is not found, sets @language_index to %PANGO_OT_DEFAULT_LANGUAGE
and the required feature of the default language system is returned in
required_feature_index. For best compatibility with some fonts, also
searches the language system tag 'dflt' before falling back to the default
language system, but that is transparent to the user. The user can simply
ignore the return value of this function to automatically fall back to the
default language system.

either, %PANGO_OT_NO_SCRIPT is placed in @script_index.

All other functions taking an input script_index parameter know
how to handle %PANGO_OT_NO_SCRIPT, so one can ignore the return

<function name="pango_ot_ruleset_new_for">
<description>
Creates a new `PangoOTRuleset` for the given OpenType info, script, and
language.

This function is part of a convenience scheme that highly simplifies
using a `PangoOTRuleset` to represent features for a specific pair of script
and language.  So one can use this function passing in the script and
language of interest, and later try to add features to the ruleset by just
specifying the feature name or tag, without having to deal with finding
script, language, or feature indices manually.

In addition to what [ctor@PangoOT.Ruleset.new] does, this function will:

* Find the `PangoOTTag` script and language tags associated with
@script and @language using [func@PangoOT.tag_from_script] and
[func@PangoOT.tag_from_language],

* For each of table types %PANGO_OT_TABLE_GSUB and %PANGO_OT_TABLE_GPOS,
find the script index of the script tag found and the language
system index of the language tag found in that script system, using
[method@PangoOT.Info.find_script] and [method@PangoOT.Info.find_language],

* For found language-systems, if they have required feature index,
add that feature to the ruleset using [method@PangoOT.Ruleset.add_feature],

* Remember found script and language indices for both table types,
and use them in future [method@PangoOT.Ruleset.maybe_add_feature] and
[method@PangoOT.Ruleset.maybe_add_features].

Because of the way return values of [method@PangoOT.Info.find_script] and
[method@PangoOT.Info.find_language] are ignored, this function automatically
finds and uses the 'DFLT' script and the default language-system.

<description>
Reads an entire line from a file into a buffer.

Lines may be delimited with '\n', '\r', '\n\r', or '\r\n'. The delimiter
is not written into the buffer. Text after a '#' character is treated as
a comment and skipped. '\' can be used to escape a # character.
'\' proceeding a line delimiter combines adjacent lines. A '\' proceeding
any other character is ignored and written into the output buffer
unmodified.

Draws the glyphs in @glyph_item with the specified `PangoRenderer`,

output format supports it.

This is useful for rendering text in PDF.

Note that this method does not handle attributes in @glyph_item.
If you want colors, shapes and lines handled automatically according
to those attributes, you need to use pango_renderer_draw_layout_line()
or pango_renderer_draw_layout().

Note that @text is the start of the text for layout, which is then
indexed by `glyph_item-&gt;item-&gt;offset`.

If @text is %NULL, this simply calls [method@Pango.Renderer.draw_glyphs].

<function name="pango_script_get_sample_language">
<description>
Finds a language tag that is reasonably representative of @script.

The language will usually be the most widely spoken or used language
written in that script: for instance, the sample language for
%PANGO_SCRIPT_CYRILLIC is ru (Russian), the sample language for
%PANGO_SCRIPT_ARABIC is ar.

For some scripts, no sample language will be returned because
there is no language that is sufficiently representative. The
best example of this is %PANGO_SCRIPT_HAN, where various different
variants of written Chinese, Japanese, and Korean all use
significantly different sets of Han characters and forms
of shared characters. No sample language can be provided
for many historical scripts as well.

As of 1.18, this function checks the environment variables
`PANGO_LANGUAGE` and `LANGUAGE` (checked in that order) first.
If one of them is set, it is parsed as a list of language tags
separated by colons or other separators. This function
will return the first language in the parsed list that Pango
believes may use @script for writing. This last predicate
is tested using [method@Pango.Language.includes_script]. This can
be used to control Pango's font selection for non-primary
languages. For example, a `PANGO_LANGUAGE` enviroment variable
set to &quot;en:fa&quot; makes Pango choose fonts suitable for Persian (fa)
instead of Arabic (ar) when a segment of Arabic text is found
in an otherwise non-Arabic text. The same trick can be used to
choose a default language for %PANGO_SCRIPT_HAN when setting
context language is not feasible.
