GlyphVisAttrRef

public struct GlyphVisAttrRef : GlyphVisAttrProtocol

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.

The GlyphVisAttrRef type acts as a lightweight Swift reference to an underlying PangoGlyphVisAttr instance. It exposes methods that can operate on this data type through GlyphVisAttrProtocol conformance. Use GlyphVisAttrRef only as an unowned reference to an existing PangoGlyphVisAttr instance.

    For type-safe access, use the generated, typed pointer _ptr property instead.
