All attributes that start or end inside a cluster are applied

<doc xml:space="preserve">A #PangoGlyphItemIter is an iterator over the clusters in a
#PangoGlyphItem. The <firstterm>forward direction</firstterm> of the
iterator is the logical direction of text. That is, with increasing
@start_index and @start_char values. If @glyph_item is right-to-left
(that is, if <literal>@glyph_item->item->analysis.level</literal> is odd),
then @start_glyph decreases as the iterator moves forward. Moreover,
in right-to-left cases, @start_glyph is greater than @end_glyph.
An iterator should be initialized using either of
pango_glyph_item_iter_init_start() and
pango_glyph_item_iter_init_end(), for forward and backward iteration
respectively, and walked over using any desired mixture of
pango_glyph_item_iter_next_cluster() and
pango_glyph_item_iter_prev_cluster(). A common idiom for doing a
forward iteration over the clusters is:
<programlisting>
PangoGlyphItemIter cluster_iter;
gboolean have_cluster;
for (have_cluster = pango_glyph_item_iter_init_start (&amp;cluster_iter,
glyph_item, text);
have_cluster;
have_cluster = pango_glyph_item_iter_next_cluster (&amp;cluster_iter))
{
...
}
</programlisting>
Note that @text is the start of the text for layout, which is then
indexed by <literal>@glyph_item->item->offset</literal> to get to the
text of @glyph_item. The @start_index and @end_index values can directly
index into @text. The @start_glyph, @end_glyph, @start_char, and @end_char
values however are zero-based for the @glyph_item. For each cluster, the
item pointed at by the start variables is included in the cluster while
the one pointed at by end variables is not.
None of the members of a #PangoGlyphItemIter should be modified manually.</doc>

Note that this can change over the life of an application.
On Unix systems, this is the return value is derived from
<literal>setlocale(LC_CTYPE, NULL)</literal>, 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 <literal>setlocale(LC_ALL, "");</literal>
for the user settings to take effect. Gtk+ does this in its initialization
functions automatically (by calling gtk_set_locale()).
See <literal>man setlocale</literal> for more details.</doc>

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 first line of each paragraph is ellipsized.
This behvaior may be changed in the future to act per layout instead of per
paragraph. File a bug against pango at <ulink
url="http://bugzilla.gnome.org/">http://bugzilla.gnome.org/</ulink> 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.

always transforms to the same vector. If (@x1,@y1) transforms
to (@x2,@y2) then (@x1+@dx1,@y1+@dy1) will transform to

If you have a rectangle in device units (pixels), use

If you have the rectangle in Pango units and want to convert to

(using this function) and pass the result to pango_extents_to_pixels(),
first argument, for an inclusive rounded rectangle.

to pixels first and then transform, for example when the transformed

example).</doc>

version="1.4">
<doc xml:space="preserve">Given a script, finds a language tag that is reasonably
representative of that script. This will usually be the
most widely spoken or used language written in that script:
for instance, the sample language for %PANGO_SCRIPT_CYRILLIC
is <literal>ru</literal> (Russian), the sample language
for %PANGO_SCRIPT_ARABIC is <literal>ar</literal>.
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 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 "en:fa" 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.</doc>

On Unix systems, this is the return value is derived from
<literal>setlocale(LC_CTYPE, NULL)</literal>, 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 <literal>setlocale(LC_ALL, "");</literal>
for the user settings to take effect. Gtk+ does this in its initialization
functions automatically (by calling gtk_set_locale()).

as an accelerator will receive a %PANGO_UNDERLINE_LOW attribute,
and the first character so marked will be returned in @accel_char,
when calling 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 pango_markup_parser_finish() to get the data out
of it, and then use g_markup_parse_context_free() to free it.
This function is designed for applications that read pango markup
from streams. To simply parse a string containing pango markup,
the simpler pango_parse_markup() API is recommended instead.</doc>

for instance, the sample language for %PANGO_SCRIPT_CYRILLIC
is <literal>ru</literal> (Russian), the sample language
for %PANGO_SCRIPT_ARABIC is <literal>ar</literal>.
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 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 "en:fa" 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

%PANGO_VERSION_MAJOR, %PANGO_VERSION_MINOR, %PANGO_VERSION_MICRO

a check that the library in use at run-time is compatible with
the version of Pango the application or module was compiled against.
Compatibility is defined by two things: first the version
of the running library is newer than the version
@required_major.required_minor.@required_micro. Second
the running library must be binary compatible with the
version @required_major.required_minor.@required_micro
(same major version.)
For compile-time version checking use PANGO_VERSION_CHECK().</doc>
