GI.HarfBuzz.Structs.ColorStopT

Information about a color stop on a color line.

Color lines typically have offsets ranging between 0 and 1, but that is not required.

Note: despite color being unpremultiplied here, interpolation in gradients shall happen in premultiplied space. See the OpenType spec COLR section for details.

Since: 7.0.0

Methods

Properties

color

the color, unpremultiplied

getColorStopTColor :: MonadIO m => ColorStopT -> m Word32

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

get colorStopT #color

setColorStopTColor :: MonadIO m => ColorStopT -> Word32 -> m ()

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

set colorStopT [ #color := value ]

isForeground

whether the color is the foreground

getColorStopTIsForeground :: MonadIO m => ColorStopT -> m Int32

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

get colorStopT #isForeground

setColorStopTIsForeground :: MonadIO m => ColorStopT -> Int32 -> m ()

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

set colorStopT [ #isForeground := value ]

offset

the offset of the color stop

getColorStopTOffset :: MonadIO m => ColorStopT -> m Float

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

get colorStopT #offset

setColorStopTOffset :: MonadIO m => ColorStopT -> Float -> m ()

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

set colorStopT [ #offset := value ]
