Appends utf8 text, converting it to glyphs and connecting it as specified by rules. You cannot expect anything about language-specific typesetting rules, so if the given script does not use trivial placement, you should better avoid this

Returns :


gnome_glyphlist_advance ()

void                gnome_glyphlist_advance             (GnomeGlyphList *gl,
                                                         gboolean advance);

Whether or not to move the pen position by the font standard advance vector. Advancing happens immediately after glyph is sent through pipeline.

void                gnome_glyphlist_kerning             (GnomeGlyphList *gl,
                                                         gdouble kerning);

Amount of kerning to add between glyphs connected by an advance rule. It is specified as fraction of a full kerning value If a glyph is manually positioned, the kerning value is ignored Kerning will be added immediately before placing a new glyph FIXME: What does the last sentence mean? (Chema)


gnome_glyphlist_letterspace ()

void                gnome_glyphlist_letterspace         (GnomeGlyphList *gl,

Amount of white space to add between glyphs connected by an advance rule. It is specified in font units (i.e. 12 for 12pt font is the width of an em square). If glyph is manually positioned, letterspace value will be ignored. Letterspace will be added immediately before placing a new glyph FIXME: what does the last sentence mean? (Chema)
