• protected IconInfo ()
• public IconInfo.for_pixbuf (IconTheme icon_theme, Pixbuf pixbuf)
  Creates a IconInfo for a Pixbuf.

Methods:

• public bool get_attach_points (out Point[] points)
  This function is deprecated and always returns false.
• public int get_base_scale ()
  Gets the base scale for the icon.
• public int get_base_size ()
  Gets the base size for the icon.
• public unowned Pixbuf? get_builtin_pixbuf ()
  Gets the built-in image for this icon, if any.
• public unowned string get_display_name ()
  This function is deprecated and always returns null.
• public bool get_embedded_rect (out Rectangle rectangle)
  This function is deprecated and always returns false.
• public unowned string? get_filename ()
  Gets the filename for the icon.
• public bool is_symbolic ()
  Checks if the icon is symbolic or not.
• public Pixbuf load_icon () throws Error
  Renders an icon previously looked up in an icon theme using lookup_icon; the size will be based on the size passed to lookup_icon.
• public async Pixbuf load_icon_async (Cancellable? cancellable = null) throws Error
  Asynchronously load, render and scale an icon previously looked up from the icon theme using lookup_icon.
• public Surface load_surface (Window? for_window) throws Error
  Renders an icon previously looked up in an icon theme using lookup_icon; the size will be based on the size passed to lookup_icon.
• public Pixbuf load_symbolic (RGBA fg, RGBA? success_color = null, RGBA? warning_color = null, RGBA? error_color = null, out bool was_symbolic = null) throws Error
  Loads an icon, modifying it to match the system colours for the foreground, success, warning and error colors provided.
• public async Pixbuf load_symbolic_async (RGBA fg, RGBA? success_color = null, RGBA? warning_color = null, RGBA? error_color = null, Cancellable? cancellable = null, out bool was_symbolic = null) throws Error
  Asynchronously load, render and scale a symbolic icon previously looked up from the icon theme using lookup_icon.
• public Pixbuf load_symbolic_for_context (StyleContext context, out bool was_symbolic = null) throws Error
  Loads an icon, modifying it to match the system colors for the foreground, success, warning and error colors provided.
• public async Pixbuf load_symbolic_for_context_async (StyleContext context, Cancellable? cancellable = null, out bool was_symbolic = null) throws Error
  Asynchronously load, render and scale a symbolic icon previously looked up from the icon theme using lookup_icon.
• public Pixbuf load_symbolic_for_style (Style style, StateType state, out bool was_symbolic = null) throws Error
  Loads an icon, modifying it to match the system colours for the foreground, success, warning and error colors provided.
• public void set_raw_coordinates (bool raw_coordinates)
  Sets whether the coordinates returned by get_embedded_rect and get_attach_points should be returned in their original form as specified in the icon theme, instead of scaled appropriately for the pixbuf returned by load_icon.
