Methods / Constructors
Method / Constructor		Defined By
	new Pango.GlyphString () Create a new Pango.GlyphString Create a new Pango.GlyphString
	copy () : Pango.GlyphString Copy a glyph string and associated storage. Copy a glyph string and associated storage. should be freed with pango_glyph_string_free(), or NULL if string was NULL. Returns: Pango.GlyphString	Pango.GlyphString
	extents (Font *font, Rectangle ink_rect, Rectangle logical_rect) : none Compute the logical and ink extents of a glyph string. Compute the logical and ink extents of a glyph string. See the documentation for pango_font_get_glyph_extents() for details about the interpretation of the rectangles. Parameters: Pango.Font font* Required (not null) Pango.Rectangle ink_rect Required (not null) or NULL to indicate that the result is not needed. Pango.Rectangle logical_rect Required (not null) or NULL to indicate that the result is not needed. Returns: none	Pango.GlyphString
	extents_range (Number *start, Number end, Font font, Rectangle ink_rect, Rectangle logical_rect) : none Computes the extents of a sub-portion of a glyph string. Computes the extents of a sub-portion of a glyph string. The extents are relative to the start of the glyph string range (the origin of their coordinate system is at the start of the range, not at the start of the entire glyph string). Parameters: Number start* Required (not null) Number end Required (not null) dices such that start <= index < end) Pango.Font font Required (not null) Pango.Rectangle ink_rect Required (not null) or NULL to indicate that the result is not needed. Pango.Rectangle logical_rect Required (not null) or NULL to indicate that the result is not needed. Returns: none	Pango.GlyphString
	free () : none Free a glyph string and associated storage. Free a glyph string and associated storage. Returns: none	Pango.GlyphString
	get_logical_widths (String *text, Number length, Number embedding_level) : Number Given a PangoGlyphString* resulting from pango_shape() and the corresponding text, determine the screen width corresponding to each character. Given a PangoGlyphString resulting from pango_shape() and the corresponding text, determine the screen width corresponding to each character. When multiple characters compose a single cluster, the width of the entire cluster is divided equally among the characters. See also pango_glyph_item_get_logical_widths(). Parameters: String text Required (not null) Number length Required (not null) Number embedding_level Required (not null) Returns: Number	Pango.GlyphString
	get_width () : Number Computes the logical width of the glyph string as can also be computed using pango_glyph_string_extents(). Computes the logical width of the glyph string as can also be computed using pango_glyph_string_extents(). However, since this only computes the width, it's much faster. This is in fact only a convenience function that computes the sum of geometry.width for each glyph in the glyphs. Returns: Number	Pango.GlyphString
	index_to_x (String *text, Number length, Analysis analysis, Number index_, Boolean trailing) : Number Converts from character position to x position. Converts from character position to x position. (X position is measured from the left edge of the run). Character positions are computed by dividing up each cluster into equal portions. Parameters: String text* Required (not null) Number length Required (not null) in text. Pango.Analysis analysis Required (not null) Number index_ Required (not null) Boolean trailing Required (not null) or end (TRUE) of the character. Returns: Number	Pango.GlyphString
	set_size (Number *new_len) : none Resize a glyph string to the given length. Resize a glyph string to the given length. Parameters: Number new_len* Required (not null) Returns: none	Pango.GlyphString
	x_to_index (String *text, Number length, Analysis analysis, Number x_pos) : Object Convert from x offset to character position. Convert from x offset to character position. Character positions are computed by dividing up each cluster into equal portions. In scripts where positioning within a cluster is not allowed (such as Thai), the returned value may not be a valid cursor position; the caller must combine the result with the logical attributes for the text to compute the valid cursor position. Parameters: String text* Required (not null) Number length Required (not null) in text. Pango.Analysis analysis Required (not null) Number x_pos Required (not null) Returns: index_: Number trailing: Number	Pango.GlyphString

Class / Namespace	Method / Signal / Properties
Gdk Method	Gdk.draw_glyphs (Drawable *drawable, GC gc, Font font, Number x, Number y, GlyphString glyphs*) : none This is a low-level function; 99% of text rendering should be done using gdk_draw_layout() instead.
Gdk Method	Gdk.draw_glyphs_transformed (Drawable *drawable, GC gc, Matrix matrix, Font font, Number x, Number y, GlyphString glyphs) : none Renders a PangoGlyphString* onto a drawable, possibly transforming the layed-out coordinates through a transformation matrix.
Pango Method	Pango.shape (String *text, Number length, Analysis analysis, GlyphString glyphs) : none Given a segment of text and the corresponding PangoAnalysis* structure returned from pango_itemize(), convert the characters into glyphs.
Pango.Renderer Method	draw_glyphs (Font *font, GlyphString glyphs, Number x, Number y) : none Draws the glyphs in glyphs* with the specified PangoRenderer.
PangoCairo Method	PangoCairo.glyph_string_path (Context cr, Font *font, GlyphString glyphs*) : none
PangoCairo Method	PangoCairo.show_glyph_string (Context cr, Font *font, GlyphString glyphs) : none Draws the glyphs in glyphs* in the specified cairo context.
PangoFT2 Method	PangoFT2.render (Bitmap *bitmap, Font font, GlyphString glyphs*, Number x, Number y) : none
PangoFT2 Method	PangoFT2.render_transformed (Bitmap *bitmap, Matrix matrix, Font font, GlyphString glyphs*, Number x, Number y) : none
PangoX Method	PangoX.fallback_shape (Font *font, GlyphString glyphs, String text, Number n_chars*) : none
PangoX Method	PangoX.render (Display *display, Drawable d, GC gc, Font font, GlyphString glyphs*, Number x, Number y) : none
PangoXft Method	PangoXft.picture_render (Display *display, Picture src_picture, Picture dest_picture, Font font, GlyphString glyphs, Number x, Number y) : none Renders a PangoGlyphString* onto an Xrender Picture object.
PangoXft Method	PangoXft.render (Draw *draw, Color color, Font font, GlyphString glyphs, Number x, Number y) : none Renders a PangoGlyphString* onto an XftDraw object wrapping an X drawable.
PangoXft Method	PangoXft.render_transformed (Draw *draw, Color color, Matrix matrix, Font font, GlyphString glyphs, Number x, Number y) : none Renders a PangoGlyphString* onto a XftDraw, possibly transforming the layed-out coordinates through a transformation matrix.
