Struct drawille::Canvas

pub struct Canvas { /* fields omitted */ }

A canvas object that can be used to draw to the terminal using Braille characters.

Methods

impl Canvas

fn new(width: u32, height: u32) -> Canvas

Creates a new Canvas with the given width and height.

Note that the Canvas can still draw outside the given dimensions (expanding the canvas) if a pixel is set outside the dimensions.

fn clear(&mut self)

Clears the canvas.

fn set(&mut self, x: u32, y: u32)

Sets a pixel at the specified coordinates.

fn unset(&mut self, x: u32, y: u32)

Deletes a pixel at the specified coordinates.

fn toggle(&mut self, x: u32, y: u32)

Toggles a pixel at the specified coordinates.

fn get(&self, x: u32, y: u32) -> bool

Detects whether the pixel at the given coordinates is set.

fn rows(&self) -> Vec<String>

Returns a Vec of each row of the Canvas.

Note that each row is actually four pixels high due to the fact that a single Braille character spans two by four pixels.

fn frame(&self) -> String

Draws the canvas to a String and returns it.

fn line(&mut self, x1: u32, y1: u32, x2: u32, y2: u32)

Draws a line from (x1, y1) to (x2, y2) onto the Canvas.
