Struct Canvas 

pub struct Canvas<'r> {
    pub w: u32,
    pub h: u32,
    pub rgba: Vec<u8>,
    /* private fields */
}

An RGBA canvas w × h physical pixels.

Fields

w: u32

h: u32

rgba: Vec<u8>

Implementations

impl<'r> Canvas<'r>

pub fn new(gui_w: u32, gui_h: u32, scale: u32, res: &'r Resources) -> Self

pub fn font(&mut self, id: &str) -> Arc<Font>

pub fn fill( &mut self, x1: f32, y1: f32, x2: f32, y2: f32, top: u32, bottom: u32, )

pub fn text( &mut self, text: &str, font: &str, x: f32, y: f32, color: u32, shadow: bool, )

Font.drawInBatch: the shadow pass (offset, color / 4), then the text.

pub fn text_scaled( &mut self, text: &str, font: &str, x: f32, y: f32, k: f32, color: u32, shadow: bool, )

Self::text k times its size (the host scales the pose: no rounding to whole pixels).

pub fn draw(&mut self, op: &DrawOp)

pub fn png(&self) -> Result<Vec<u8>, String>
