GI.Pango.Objects.EngineShape
Description
The EngineShape class is implemented by engines that
customize the rendering-system dependent part of the
Pango pipeline for a particular script or language.
A EngineShape implementation is then specific to both
a particular rendering system or group of rendering systems
and to a particular script. For instance, there is one
EngineShape implementation to handle shaping Arabic
for Fontconfig-based backends.
Synopsis
- newtype EngineShape = EngineShape (ManagedPtr EngineShape)
- class (GObject o, IsDescendantOf EngineShape o) => IsEngineShape o
- toEngineShape :: (MonadIO m, IsEngineShape o) => o -> m EngineShape
- noEngineShape :: Maybe EngineShape

class (GObject o, IsDescendantOf EngineShape o) => IsEngineShape o Source #
Type class for types which can be safely cast to EngineShape, for instance with toEngineShape.

toEngineShape :: (MonadIO m, IsEngineShape o) => o -> m EngineShape Source #
Cast to EngineShape, for types for which this is known to be safe. For general casts, use castTo.
noEngineShape :: Maybe EngineShape Source #
A convenience alias for Nothing :: Maybe EngineShape.
