All Implemented Interfaces:

Proxy

Enclosing class:

Renderer

public static class Renderer.RendererClass
extends GObject.ObjectClass

Class structure for PangoRenderer.

The following vfuncs take user space coordinates in Pango units and have default implementations:

• draw_glyphs
• draw_rectangle
• draw_error_underline
• draw_shape
• draw_glyph_item

The default draw_shape implementation draws nothing.

The following vfuncs take device space coordinates as doubles and must be implemented:

• draw_trapezoid
• draw_glyph
