pub struct Canvas {
    pub pixels: Vec<u8>,
    pub size: Size2D<u32>,
    pub stride: usize,
    pub format: Format,
}

An in-memory bitmap surface for glyph rasterization.

Fields

pixels: Vec<u8>

The raw pixel data.

size: Size2D<u32>

The size of the buffer, in pixels.

stride: usize

The number of bytes between successive rows.

format: Format

The image format of the canvas.

Methods

impl Canvas

pub fn new(size: &Size2D<u32>, format: Format) -> Canvas

Creates a new blank canvas with the given pixel size and format.

Stride is automatically calculated from width.

The canvas is initialized with transparent black (all values 0).

pub fn with_stride(size: &Size2D<u32>, stride: usize, format: Format) -> Canvas

Creates a new blank canvas with the given pixel size, stride (number of bytes between successive rows), and format.

The canvas is initialized with transparent black (all values 0).

Trait Implementations

impl Debug for Canvas

fn fmt(&self, f: &mut Formatter) -> Result
