Struct stdweb::web::CanvasGradient
[−]
[src]
pub struct CanvasGradient(_);
The CanvasGradient struct represents an opaque object describing a gradient. It is returned by the methods CanvasRenderingContext2D.createLinearGradient() or CanvasRenderingContext2D.createRadialGradient().
Methods
impl CanvasGradient[src]
pub fn add_color_stop(
&self,
offset: f64,
color: &str
) -> Result<(), AddColorStopError>[src]
&self,
offset: f64,
color: &str
) -> Result<(), AddColorStopError>
Adds a new stop, defined by an offset and a color, to the gradient. If the offset is
not between 0 and 1, an INDEX_SIZE_ERR is returned, if the color can't be parsed as a
CSS
