Methods

Properties

cluster

the index of the character in the original text that corresponds to this GlyphInfoT, or whatever the client passes to bufferAdd. More than one GlyphInfoT can have the same cluster value, if they resulted from the same character (e.g. one to many glyph substitution), and when more than one character gets merged in the same glyph (e.g. many to one glyph substitution) the GlyphInfoT will have the smallest cluster value of them. By default some characters are merged into the same cluster (e.g. combining marks have the same cluster as their bases) even if they are separate glyphs, bufferSetClusterLevel allow selecting more fine-grained cluster handling.

getGlyphInfoTCluster :: MonadIO m => GlyphInfoT -> m Word32

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

get glyphInfoT #cluster

setGlyphInfoTCluster :: MonadIO m => GlyphInfoT -> Word32 -> m ()

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

set glyphInfoT [ #cluster := value ]

codepoint

either a Unicode code point (before shaping) or a glyph index (after shaping).

getGlyphInfoTCodepoint :: MonadIO m => GlyphInfoT -> m Word32

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

get glyphInfoT #codepoint

setGlyphInfoTCodepoint :: MonadIO m => GlyphInfoT -> Word32 -> m ()

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

set glyphInfoT [ #codepoint := value ]
