Struct tiny_skia::Pattern

source ·
pub struct Pattern<'a> { /* private fields */ }
Expand description

A pattern shader.

Essentially a SkImageShader.

Unlike Skia, we do not support FilterQuality::Medium, because it involves mipmap generation, which adds too much complexity.

Implementations§

source§

impl<'a> Pattern<'a>

source

pub fn new( pixmap: PixmapRef<'a>, spread_mode: SpreadMode, quality: FilterQuality, opacity: f32, transform: Transform ) -> Shader<'_>

Creates a new pattern shader.

opacity will be clamped to the 0..=1 range.

impl<'a> PartialEq<Pattern<'a>> for Pattern<'a>

source§

fn eq(&self, other: &Pattern<'a>) -> bool
