Methods

Properties

tag

The hb_tag_t tag of the variation-axis name

getVariationTTag :: MonadIO m => VariationT -> m Word32

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

get variationT #tag

setVariationTTag :: MonadIO m => VariationT -> Word32 -> m ()

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

set variationT [ #tag := value ]

value

The value of the variation axis

getVariationTValue :: MonadIO m => VariationT -> m Float

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

get variationT #value

setVariationTValue :: MonadIO m => VariationT -> Float -> m ()

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

set variationT [ #value := value ]
