Struct kansas::Canvas

pub struct Canvas { /* fields omitted */ }

Methods

impl Canvas

pub fn new() -> Self

create a new Canvas

pub fn on<E: Listener>(&mut self, handler: Callback<E>)

register a function to be used as an event handler

note: as of right now, registering the same event twice will overwrite the previous handler function

pub fn off<E: Listener>(&mut self)

pub fn context_mut(&mut self) -> &mut Context

get a mutable reference to the canvas's context

pub fn pause(&mut self)

hold execution until user hits Esc

Methods from Deref<Target = Context>

pub fn dimensions(&self) -> (u32, u32)

dimensions

pub fn fill_color<C>(&mut self, color: C) where     C: CanvasColor,

set fill color

pub fn fill_rect(&mut self, x: u32, y: u32, width: u32, height: u32)

fill rectangle with preset fill color

pub fn fill_by<C, F>(&mut self, x: u32, y: u32, width: u32, height: u32, f: F) where     F: Fn(u32, u32) -> C,     C: CanvasColor,

fill rectangle using a fill function

pub fn set_pixel<C: CanvasColor>(&mut self, x: u32, y: u32, c: C)

set a pixel to a specific color

this is a low level texture operation and is not effected by preset colors or alpha blending
