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).
