[ CCode ( type_id = "pango_context_get_type ()" ) ]
public sealed class Context : Object

A `PangoContext` stores global information used to control the itemization process.

The information stored by `PangoContext` includes the fontmap used to look up fonts, and default values such as the default language, default gravity, or default font.

To obtain a `PangoContext`, use [method@Pango.FontMap.create_context].

Namespace: Pango

Package: pango

Creation methods:

public Context ()
Creates a new `PangoContext` initialized to default values.

Methods:

public void changed ()
Forces a change in the context, which will cause any `PangoLayout` using this context to re-layout.
public Direction get_base_dir ()
Retrieves the base direction for the context.
public Gravity get_base_gravity ()
Retrieves the base gravity for the context.
public unowned FontDescription? get_font_description ()
Retrieve the default font description for the context.
public unowned FontMap? get_font_map ()
Gets the `PangoFontMap` used to look up fonts for this context.
public Gravity get_gravity ()
Retrieves the gravity for the context.
public GravityHint get_gravity_hint ()
Retrieves the gravity hint for the context.
public unowned Language get_language ()
Retrieves the global language tag for the context.
public unowned Matrix? get_matrix ()
Gets the transformation matrix that will be applied when rendering with this context.
public FontMetrics get_metrics (FontDescription? desc, Language? language)
Get overall metric information for a particular font description.
public bool get_round_glyph_positions ()
Returns whether font rendering with this context should round glyph positions and widths.
public uint get_serial ()
Returns the current serial number of this.
public void list_families (out (unowned FontFamily)[] families)
List all families for a context.
public Font? load_font (FontDescription desc)
Loads the font in one of the fontmaps in the context that is the closest match for desc.
public Fontset? load_fontset (FontDescription desc, Language language)
Load a set of fonts in the context that can be used to render a font matching desc.
public void set_base_dir (Direction direction)
Sets the base direction for the context.
public void set_base_gravity (Gravity gravity)
Sets the base gravity for the context.
public void set_font_description (FontDescription? desc)
Set the default font description for the context
public void set_font_map (FontMap? font_map)
Sets the font map to be searched when fonts are looked-up in this context.
public void set_gravity_hint (GravityHint hint)
Sets the gravity hint for the context.
public void set_language (Language? language)
Sets the global language tag for the context.
public void set_matrix (Matrix? matrix)
Sets the transformation matrix that will be applied when rendering with this context.
public void set_round_glyph_positions (bool round_positions)
Sets whether font rendering with this context should round glyph positions and widths to integral positions, in device units.
