GI.Pango.Structs.GlyphVisAttr

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

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

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.

Methods

Properties

isClusterStart

set for the first logical glyph in each cluster.

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

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 ()

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

set glyphVisAttr [ #isClusterStart := value ]

isColor

set if the the font will render this glyph with color. Since 1.50

getGlyphVisAttrIsColor :: MonadIO m => GlyphVisAttr -> m Word32

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

get glyphVisAttr #isColor

setGlyphVisAttrIsColor :: MonadIO m => GlyphVisAttr -> Word32 -> m ()

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

set glyphVisAttr [ #isColor := value ]
