source ·
pub struct Canvas {
    pub pixels: Vec<u8>,
    pub size: Vector2I,
    pub stride: usize,
    pub format: Format,
}
Expand description

An in-memory bitmap surface for glyph rasterization.

Fields§

§pixels: Vec<u8>

The raw pixel data.

§size: Vector2I

The size of the buffer, in pixels.

§stride: usize

The number of bytes between successive rows.

§format: Format

The image format of the canvas.

Implementations§

source§

impl Canvas

source

pub fn new(size: Vector2I, 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).

source

pub fn with_stride(size: Vector2I, 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).
