Implementations

impl StripGenerator

pub fn new(width: u16, height: u16, level: Level) -> Self

Create a new strip generator.

pub fn generate_filled_path<'a>( &'a mut self, path: impl IntoIterator<Item = PathEl>, fill_rule: Fill, transform: Affine, anti_alias: bool, func: impl FnOnce(&'a [Strip]), )

Generate the strips for a filled path.

pub fn generate_stroked_path<'a>( &'a mut self, path: impl IntoIterator<Item = PathEl>, stroke: &Stroke, transform: Affine, anti_alias: bool, func: impl FnOnce(&'a [Strip]), )

Generate the strips for a stroked path.

pub fn alpha_buf(&self) -> &[u8]

Return a reference to the current alpha buffer of the strip generator.

pub fn extend_alpha_buf(&mut self, alphas: &[u8])

Extend the alpha buffer with the given alphas.

pub fn set_alpha_buf(&mut self, alpha_buf: Vec<u8>)

Set the alpha buffer.

pub fn take_alpha_buf(&mut self) -> Vec<u8>

Take the alpha buffer and set it to an empty one.

pub fn replace_alpha_buf(&mut self, alphas: Vec<u8>) -> Vec<u8>

Swap the alpha buffer with the given one.

pub fn reset(&mut self)

Reset the strip generator.

fn make_strips(&mut self, fill_rule: Fill, anti_alias: bool)
