pub fn add_color_stop_rgb(&self, offset: f64, red: f64, green: f64, blue: f64)

Methods from Deref<Target = Pattern>§
sourcepub fn set_user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>,
value: Rc<T>
) -> Result<(), Error>
pub fn set_user_data<T: 'static>( &self, key: &'static UserDataKey<T>, value: Rc<T> ) -> Result<(), Error>
Attach user data to self for the given key.
sourcepub fn user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Option<Rc<T>>
pub fn user_data<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Option<Rc<T>>
Return the user data previously attached to self with the given key, if any.
sourcepub fn user_data_ptr<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Option<NonNull<T>>
pub fn user_data_ptr<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Option<NonNull<T>>
Return the user data previously attached to self with the given key, if any,
without incrementing the reference count.
The pointer is valid when it is returned from this method,
until the cairo object that self represents is destroyed
or remove_user_data or set_user_data is called with the same key.
sourcepub fn remove_user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Result<(), Error>
pub fn remove_user_data<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Result<(), Error>
Unattached from self the user data associated with key, if any.
If there is no other Rc strong reference, the data is destroyed.
