GI.Pango.Structs.GlyphVisAttr

Description

The PangoGlyphVisAttr is used to communicate information between the shaping phase and the rendering phase. More attributes may be added in the future.

Methods

new :: MonadIO m => (ManagedPtr GlyphVisAttr -> GlyphVisAttr) -> [AttrOp GlyphVisAttr tag] -> m GlyphVisAttr #

noGlyphVisAttr :: Maybe GlyphVisAttr Source #

A convenience alias for Nothing :: Maybe GlyphVisAttr.

Methods

Overloaded 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 ]
