Methods / Constructors
Method / Constructor		Defined By
	new Pango.Renderer (Object *properties) Create a new Pango.Renderer Create a new Pango.Renderer Parameters: Object properties*
	activate () : none Does initial setup before rendering operations on renderer. Does initial setup before rendering operations on renderer. pango_renderer_deactivate() should be called when done drawing. Calls such as pango_renderer_draw_layout() automatically activate the layout before drawing on it. Calls to pango_renderer_activate() and pango_renderer_deactivate() can be nested and the renderer will only be initialized and deinitialized once. Returns: none	Pango.Renderer
	deactivate () : none Cleans up after rendering operations on renderer. Cleans up after rendering operations on renderer. See docs for pango_renderer_activate(). Returns: none	Pango.Renderer
	draw_error_underline (gint32 x, gint32 y, gint32 *width, gint32 height) : none Draw a squiggly line that approximately covers the given rectangle in the style of an underline used to indicate a spelling error. Draw a squiggly line that approximately covers the given rectangle in the style of an underline used to indicate a spelling error. (The width of the underline is rounded to an integer number of up/down segments and the resulting rectangle is centered in the original rectangle) This should be called while renderer* is already active. Use pango_renderer_activate() to activate a renderer. Parameters: gint32 x Required (not null) X coordinate of underline, in Pango units in user coordinate system gint32 y Required (not null) Y coordinate of underline, in Pango units in user coordinate system gint32 width Required (not null) width of underline, in Pango units in user coordinate system gint32 height Required (not null) height of underline, in Pango units in user coordinate system Returns: none	Pango.Renderer
	draw_glyph (Font *font, guint32 glyph, gdouble x, gdouble y) : none Draws a single glyph with coordinates in device space. Draws a single glyph with coordinates in device space. Parameters: Pango.Font font* Required (not null) a PangoFont guint32 glyph Required (not null) the glyph index of a single glyph gdouble x Required (not null) X coordinate of left edge of baseline of glyph gdouble y Required (not null) Y coordinate of left edge of baseline of glyph Returns: none	Pango.Renderer
	draw_glyph_item (String *text, GlyphItem glyph_item, gint32 x, gint32 y) : none 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 (PDF for example). 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 (PDF for example). Note that text is the start of the text for layout, which is then indexed by glyph_item->item->offset. If text is NULL, this simply calls pango_renderer_draw_glyphs(). The default implementation of this method simply falls back to pango_renderer_draw_glyphs(). Parameters: String text Required (not null) the UTF-8 text that glyph_item refers to, or NULL Pango.GlyphItem glyph_item Required (not null) a PangoGlyphItem gint32 x Required (not null) X position of left edge of baseline, in user space coordinates in Pango units. gint32 y Required (not null) Y position of left edge of baseline, in user space coordinates in Pango units. Returns: none	Pango.Renderer
	draw_glyphs (Font *font, GlyphString glyphs, gint32 x, gint32 y) : none Draws the glyphs in glyphs* with the specified PangoRenderer. Draws the glyphs in glyphs with the specified PangoRenderer. Parameters: Pango.Font font Required (not null) a PangoFont Pango.GlyphString glyphs Required (not null) a PangoGlyphString gint32 x Required (not null) X position of left edge of baseline, in user space coordinates in Pango units. gint32 y Required (not null) Y position of left edge of baseline, in user space coordinates in Pango units. Returns: none	Pango.Renderer
	draw_layout (Layout *layout, gint32 x, gint32 y) : none Draws layout* with the specified PangoRenderer. Draws layout with the specified PangoRenderer. Parameters: Pango.Layout layout Required (not null) a PangoLayout gint32 x Required (not null) X position of left edge of baseline, in user space coordinates in Pango units. gint32 y Required (not null) Y position of left edge of baseline, in user space coordinates in Pango units. Returns: none	Pango.Renderer
	draw_layout_line (LayoutLine *line, gint32 x, gint32 y) : none Draws line* with the specified PangoRenderer. Draws line with the specified PangoRenderer. Parameters: Pango.LayoutLine line Required (not null) a PangoLayoutLine gint32 x Required (not null) X position of left edge of baseline, in user space coordinates in Pango units. gint32 y Required (not null) Y position of left edge of baseline, in user space coordinates in Pango units. Returns: none	Pango.Renderer
	draw_rectangle (RenderPart *part, gint32 x, gint32 y, gint32 width, gint32 height) : none Draws an axis-aligned rectangle in user space coordinates with the specified PangoRenderer. Draws an axis-aligned rectangle in user space coordinates with the specified PangoRenderer. This should be called while renderer* is already active. Use pango_renderer_activate() to activate a renderer.

	draw_trapezoid (RenderPart *part, gdouble y1_, gdouble x11, gdouble x21, gdouble y2, gdouble x12, gdouble x22) : none Draws a trapezoid with the parallel sides aligned with the X axis using the given PangoRenderer; coordinates are in device space. Draws a trapezoid with the parallel sides aligned with the X axis using the given PangoRenderer; coordinates are in device space. Parameters: Pango.RenderPart part* Required (not null) type of object this trapezoid is part of gdouble y1_ Required (not null) Y coordinate of top of trapezoid gdouble x11 Required (not null) X coordinate of left end of top of trapezoid gdouble x21 Required (not null) X coordinate of right end of top of trapezoid gdouble y2 Required (not null) Y coordinate of bottom of trapezoid gdouble x12 Required (not null) X coordinate of left end of bottom of trapezoid gdouble x22 Required (not null) X coordinate of right end of bottom of trapezoid Returns: none	Pango.Renderer
	get_color (RenderPart *part) : Pango.Color Gets the current rendering color for the specified part. Gets the current rendering color for the specified part. if it hasn't been set and should be inherited from the environment. Parameters: Pango.RenderPart part* Required (not null) the part to get the color for Returns: Pango.Color the color for the specified part, or NULL	Pango.Renderer
	get_layout_line () : Pango.LayoutLine Gets the layout line currently being rendered using renderer. Gets the layout line currently being rendered using renderer. Calling this function only makes sense from inside a subclass's methods, like in its draw_shape() for example. The returned layout line should not be modified while still being rendered. rendered using renderer at this time. Returns: Pango.LayoutLine the layout line, or NULL if no layout line is being	Pango.Renderer
	get_matrix () : Pango.Matrix Gets the transformation matrix that will be applied when rendering. Gets the transformation matrix that will be applied when rendering. See pango_renderer_set_matrix(). (which is the same as the identity matrix). The returned matrix is owned by Pango and must not be modified or freed. Returns: Pango.Matrix the matrix, or NULL if no matrix has been set	Pango.Renderer
	part_changed (RenderPart *part) : none Informs Pango that the way that the rendering is done for part* has changed in a way that would prevent multiple pieces being joined together into one drawing call. Informs Pango that the way that the rendering is done for part has changed in a way that would prevent multiple pieces being joined together into one drawing call. For instance, if a subclass of PangoRenderer was to add a stipple option for drawing underlines, it needs to call pango_renderer_part_changed (render, PANGO_RENDER_PART_UNDERLINE); When the stipple changes or underlines with different stipples might be joined together. Pango automatically calls this for changes to colors. (See pango_renderer_set_color()) Parameters: Pango.RenderPart part Required (not null) the part for which rendering has changed. Returns: none	Pango.Renderer
	set_color (RenderPart *part, Color color) : none Sets the color for part of the rendering. Sets the color for part of the rendering. Parameters: Pango.RenderPart part* Required (not null) the part to change the color of Pango.Color color Required (not null) the new color or NULL to unset the current color Returns: none	Pango.Renderer
	set_matrix (Matrix *matrix) : none Sets the transformation matrix that will be applied when rendering. Sets the transformation matrix that will be applied when rendering. Parameters: Pango.Matrix matrix* Required (not null) a PangoMatrix, or NULL to unset any existing matrix. (No matrix set is the same as setting the identity matrix.) Returns: none	Pango.Renderer
