### Struct

# Pango GlyphVisAttr

#### Description [src]

    struct PangoGlyphVisAttr {
      guint is_cluster_start;
    }

A `PangoGlyphVisAttr` structure communicates information between the shaping and rendering phases.

Currently, it contains only cluster start information. More attributes may be added in the future.

###### Structure members

`is_cluster_start` | Set for the first logical glyph in each cluster. (Clusters are stored in visual order, within the cluster, glyphs are always ordered in logical order, since visual order is meaningless; that is, in Arabic text, accent glyphs follow the glyphs for the base character.)
