Implementations§

source§

impl BoundsBuilder

source

pub fn new( x: Option<f64>, y: Option<f64>, width: Option<f64>, height: Option<f64>, transform: Transform ) -> Self

Constructs a new BoundsBuilder.

source

pub fn add_input(self, input: &FilterInput) -> Self

Adds a filter primitive input to the bounding box.

source

pub fn compute(self, ctx: &FilterContext) -> Bounds

Returns the final exact bounds, both with and without clipping to the effects region.
