Struct Paint 

pub struct Paint { /* private fields */ }

A colour prepared for drawing.

Premultiplication happens once here rather than once per pixel. Constructing a Paint is the only division-by-255 in a fill.

Implementations

impl Paint

pub const fn new(color: Color) -> Paint

Prepares a colour for drawing.

pub const fn premultiplied(self) -> u32

The premultiplied 0xAARRGGBB word.

pub const fn alpha(self) -> u32

Straight alpha, 0..=255.

pub const fn is_opaque(self) -> bool

Returns true if drawing can skip the read-modify-write and just store.

pub const fn is_invisible(self) -> bool

Returns true if drawing would change nothing.

pub const fn scaled(self, coverage: u32) -> Paint

This paint scaled by an anti-aliasing coverage of 0..=255.
