Struct font_kit::canvas::Canvas

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

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

impl Canvas

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).

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).

pub(crate) fn blit_from_canvas(&mut self, src: &Canvas)

pub(crate) fn blit_from( &mut self, dst_point: Vector2I, src_bytes: &[u8], src_size: Vector2I, src_stride: usize, src_format: Format, )

pub(crate) fn blit_from_bitmap_1bpp( &mut self, dst_point: Vector2I, src_bytes: &[u8], src_size: Vector2I, src_stride: usize, )

fn blit_from_with<B: Blit>( &mut self, rect: RectI, src_bytes: &[u8], src_stride: usize, src_format: Format, )

Trait Implementations

impl Debug for Canvas

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

Formats the value using the given formatter.
