Creation methods:

• protected Renderer ()

Methods:

• public void activate ()
  Does initial setup before rendering operations on this.
• public virtual void begin ()
• public void deactivate ()
  Cleans up after rendering operations on this.
• public virtual void draw_error_underline (int x, int y, int width, int height)
  Draw a squiggly line that approximately covers the given rectangle in the style of an underline used to indicate a spelling error.
• public virtual void draw_glyph (Font font, Glyph glyph, double x, double y)
  Draws a single glyph with coordinates in device space.
• public virtual void draw_glyph_item (string? text, GlyphItem glyph_item, int x, int y)
  Draws the glyphs in glyph_item with the specified `PangoRenderer`, embedding the text associated with the glyphs in the output if the output format supports it.
• public virtual void draw_glyphs (Font font, GlyphString glyphs, int x, int y)
  Draws the glyphs in glyphs with the specified `PangoRenderer`.
• public void draw_layout (Layout layout, int x, int y)
  Draws layout with the specified `PangoRenderer`.
• public void draw_layout_line (LayoutLine line, int x, int y)
  Draws line with the specified `PangoRenderer`.
• public virtual void draw_rectangle (RenderPart part, int x, int y, int width, int height)
  Draws an axis-aligned rectangle in user space coordinates with the specified `PangoRenderer`.
• public virtual void draw_shape (AttrShape attr, int x, int y)
• public virtual void draw_trapezoid (RenderPart part, double y1_, double x11, double x21, double y2, double x12, double x22)
  Draws a trapezoid with the parallel sides aligned with the X axis using the given `PangoRenderer`; coordinates are in device space.
• public virtual void end ()

• public unowned Matrix? get_matrix ()
  Gets the transformation matrix that will be applied when rendering.
• public virtual void part_changed (RenderPart part)
  Informs Pango that the way that the rendering is done for part has changed.
• public virtual void prepare_run (LayoutRun run)
• public void set_alpha (RenderPart part, uint16 alpha)
  Sets the alpha for part of the rendering.
• public void set_color (RenderPart part, Color? color)
  Sets the color for part of the rendering.
• public void set_matrix (Matrix? matrix)
