### Method

# Pango GlyphString index_to_x

#### Declaration [src]

    void
    pango_glyph_string_index_to_x (
      PangoGlyphString* glyphs,
      const char* text,
      int length,
      PangoAnalysis* analysis,
      int index_,
      gboolean trailing,
      int* x_pos
    )

#### Description [src]

Converts from character position to x position.

The X position is measured from the left edge of the run. Character positions are obtained using font metrics for ligatures where available, and computed by dividing up each cluster into equal portions, otherwise.
