GI.Pango.Structs.GlyphVisAttr

Description

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

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

Construct a GlyphVisAttr struct initialized to zero.

Methods

Properties

isClusterStart

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.)

getGlyphVisAttrIsClusterStart :: MonadIO m => GlyphVisAttr -> m Word32 Source #

Get the value of the “is_cluster_start” field. When overloading is enabled, this is equivalent to

get glyphVisAttr #isClusterStart

setGlyphVisAttrIsClusterStart :: MonadIO m => GlyphVisAttr -> Word32 -> m () Source #

Set the value of the “is_cluster_start” field. When overloading is enabled, this is equivalent to

set glyphVisAttr [ #isClusterStart := value ]
