Required Methods
sourcefn from_image(image: Self::Image, range: f64, mid_value: f32) -> Self
fn from_image(image: Self::Image, range: f64, mid_value: f32) -> Self
Create an SDF from an image.
sourcefn render(&self, width: u32, height: u32) -> GrayFImage
fn render(&self, width: u32, height: u32) -> GrayFImage
Render this SDF to a single-channel float image of specified size.
sourcefn render_colored(&self, width: u32, height: u32) -> Self::ColoredOutput
fn render_colored(&self, width: u32, height: u32) -> Self::ColoredOutput
Render this SDF to a multi-channel float image of specified size. Colors represent MSDF edge colors.
