Struct piet_svg::RenderContext

pub struct RenderContext { /* fields omitted */ }

piet::RenderContext for generating SVG images

Implementations

impl RenderContext

pub fn new() -> Self

Construct an empty RenderContext

pub fn write(&self, writer: impl Write) -> Result<()>

Write graphics rendered so far to an std::io::Write impl, such as std::fs::File

Additional rendering can be done afterwards.
