impl RadialGradient

source

pub fn new(x0: f64, y0: f64, r0: f64, x1: f64, y1: f64, r1: f64) -> Self

pub fn radial_circles(&self) -> Result<(f64, f64, f64, f64, f64, f64), Error>

Methods from Deref<Target = Gradient>

source

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

source

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

source

pub fn color_stop_count(&self) -> Result<isize, Error>

source

pub fn color_stop_rgba(
&self,
index: isize
) -> Result<(f64, f64, f64, f64, f64), Error>

Methods from Deref<Target = Pattern>

source

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.

source

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.

source

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.

source

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.
