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

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.)
