Abstract renderer for grid graphics.

All coordinates are in centimeters from the device origin (bottom-left). The renderer converts these to whatever coordinate system the backend uses.

Required Methods

fn line(&mut self, x0_cm: f64, y0_cm: f64, x1_cm: f64, y1_cm: f64, gp: &Gpar)

Draw a single line segment.

fn polyline(&mut self, x_cm: &[f64], y_cm: &[f64], gp: &Gpar)

Draw a connected polyline (multiple segments sharing endpoints).

fn rect(&mut self, x_cm: f64, y_cm: f64, w_cm: f64, h_cm: f64, gp: &Gpar)

Draw a rectangle.

fn circle(&mut self, x_cm: f64, y_cm: f64, r_cm: f64, gp: &Gpar)

Draw a circle.

fn polygon(&mut self, x_cm: &[f64], y_cm: &[f64], gp: &Gpar)

Draw a filled polygon.

fn text(&mut self, x_cm: f64, y_cm: f64, label: &str, rot: f64, gp: &Gpar)

Draw a text label.

fn point(&mut self, x_cm: f64, y_cm: f64, pch: u8, size_cm: f64, gp: &Gpar)

Draw a point (plotting symbol).

fn clip(&mut self, x_cm: f64, y_cm: f64, w_cm: f64, h_cm: f64)

Set a clipping rectangle. All subsequent drawing is clipped to this region.

fn unclip(&mut self)

Remove the most recently set clipping rectangle.

fn device_size_cm(&self) -> (f64, f64)

Return the device size in centimeters (width, height).
