Namespaces:

Interfaces:

• CairoFont - `PangoCairoFont` is an interface exported by fonts for use with Cairo.
• CairoFontMap - `PangoCairoFontMap` is an interface exported by font maps for use with Cairo.

Delegates:

• public delegate void CairoShapeRendererFunc (Context cr, AttrShape attr, bool do_path)
  Function type for rendering attributes of type pango_attr_shape with Pango's Cairo renderer.

Methods:

• public unowned FontOptions? cairo_context_get_font_options (Context context)
  Retrieves any font rendering options previously set with [func@PangoCairo.
• public double cairo_context_get_resolution (Context context)
  Gets the resolution for the context.
• public unowned CairoShapeRendererFunc? cairo_context_get_shape_renderer (Context context)
  Sets callback function for context to use for rendering attributes of type pango_attr_shape.
• public void cairo_context_set_font_options (Context context, FontOptions? options)
  Sets the font options used when rendering text with this context.
• public void cairo_context_set_resolution (Context context, double dpi)
  Sets the resolution for the context.
• public void cairo_context_set_shape_renderer (Context context, owned CairoShapeRendererFunc? func)
  Sets callback function for context to use for rendering attributes of type pango_attr_shape.
• public Context cairo_create_context (Context cr)
  Creates a context object set up to match the current transformation and target surface of the Cairo context.
• public Layout cairo_create_layout (Context cr)
  Creates a layout object set up to match the current transformation and target surface of the Cairo context.
• public void cairo_error_underline_path (Context cr, double x, double y, double width, double height)
  Add a squiggly line to the current path in the specified cairo context that approximately covers the given rectangle in the style of an underline used to indicate a spelling error.
• public unowned FontMap cairo_font_map_get_default ()
• public FontMap cairo_font_map_new ()
• public FontMap? cairo_font_map_new_for_font_type (FontType fonttype)
• public void cairo_glyph_string_path (Context cr, Font font, GlyphString glyphs)
  Adds the glyphs in glyphs to the current path in the specified cairo context.
• public void cairo_layout_line_path (Context cr, LayoutLine line)
  Adds the text in `PangoLayoutLine` to the current path in the specified cairo context.
• public void cairo_layout_path (Context cr, Layout layout)
  Adds the text in a `PangoLayout` to the current path in the specified cairo context.
• public void cairo_show_error_underline (Context cr, double x, double y, double width, double height)
  Draw a squiggly line in the specified cairo context that approximately covers the given rectangle in the style of an underline used to indicate a spelling error.
• public void cairo_show_glyph_item (Context cr, string text, GlyphItem glyph_item)
  Draws the glyphs in glyph_item in the specified cairo context,
• public void cairo_show_glyph_string (Context cr, Font font, GlyphString glyphs)
  Draws the glyphs in glyphs in the specified cairo context.
• public void cairo_show_layout (Context cr, Layout layout)
  Draws a `PangoLayout` in the specified cairo context.
• public void cairo_show_layout_line (Context cr, LayoutLine line)
  Draws a `PangoLayoutLine` in the specified cairo context.
• public void cairo_update_context (Context cr, Context context)
  Updates a `PangoContext` previously created for use with Cairo to match the current transformation and target surface of a Cairo context.
• public void cairo_update_layout (Context cr, Layout layout)
  Updates the private `PangoContext` of a `PangoLayout` created with [ func@create_layout] to match the current transformation and target surface of a Cairo context.
