<!-- ##### STRUCT PangoColor ##### -->
<para>

represent a color in an uncalibrated RGB color-space.
</para>

@red: The red component of the color. This is a value between 0 and 65535, 
      with 65535 indicating full intensity.
@green: The green component of the color. This is a value between 0 and 65535, 
      with 65535 indicating full intensity.

      with 65535 indicating full intensity.

<!-- ##### MACRO PANGO_TYPE_COLOR ##### -->
<para>
The #GObject type for #PangoColor.
</para>

</para>



<!-- ##### FUNCTION pango_language_from_string ##### -->
<para>

</para>

@language: 
@Returns: 


<!-- ##### MACRO pango_language_to_string ##### -->
<para>
Returns a RFC-3066 format string representing the given language tag. 
</para>

@language: a language tag.
@Returns: a string representing the language tag.


<!-- ##### FUNCTION pango_language_matches ##### -->
<para>

</para>

@language: 
@range_list: 
@Returns: 


<!-- ##### STRUCT PangoAttrList ##### -->
<para>
The #PangoAttrList structure represents a list of attributes
that apply to a section of text. The attributes are, in general,
allowed to overlap in an arbitrary fashion, however, if the
attributes are manipulated only through pango_attr_list_change(),
the overlap between properties will meet stricter criteria.
</para>
<para>
Since the #PangoAttrList structure is stored as a linear list,
it is not suitable for storing attributes for large amounts
of text. In general, you should not use a single #PangoAttrList
for more than one paragraph of text.
</para>


<!-- ##### MACRO PANGO_TYPE_ATTR_LIST ##### -->
<para>
The #GObject type for #PangoAttrList.
</para>

A predicate function used by pango_attr_list_filter()
to filter out a subset of attributes for a list.
</para>

@attribute: a #PangoAttribute
@data: callback data passed to pango_attr_list_filter()
@Returns: %TRUE if the attribute should be filtered out


<!-- ##### FUNCTION pango_attr_list_get_iterator ##### -->
<para>

</para>

@list: 
@Returns: 


<!-- ##### STRUCT PangoAttrIterator ##### -->
<para>
The #PangoAttrIterator structure is used to represent an
iterator through a #PangoAttrList. A new iterator is created
with pango_attr_list_get_iterator(). Once the iterator
is created, it can be advanced through the style changes
in the text using pango_attr_iterator_next(). At each
style change, the range of the current style segment and the
attributes currently in effect can be queried.
