Enum Canvas 

#[non_exhaustive]
pub enum Canvas {
    Raster {
        width: u32,
        height: u32,
        pixel_format: PixelFormat,
    },
    Vector {
        width: f32,
        height: f32,
        unit: LengthUnit,
    },
}

Canvas — either pixel-based (NLE, compositor) or vector-coord (PDF pages).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Raster

Pixel raster. Used by the streaming compositor and the NLE timeline.

Fields

width: u32

height: u32

pixel_format: PixelFormat

Vector

Unit-agnostic vector canvas. PDF pages use this; the unit is whatever the producer declared. All scene coordinates live in this unit; rasterisation happens at export time.

Fields

width: f32

height: f32

unit: LengthUnit

Implementations

impl Canvas

pub const fn raster(width: u32, height: u32) -> Self

Convenience for the common case: 8-bit 4:2:0 raster.

pub fn raster_size(&self) -> Option<(u32, u32)>

Pixel dims for raster canvases, None for vector canvases.

Trait Implementations

impl Clone for Canvas

fn clone(&self) -> Canvas

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Canvas

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

Formats the value using the given formatter.

impl PartialEq for Canvas

fn eq(&self, other: &Canvas) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Canvas

impl StructuralPartialEq for Canvas
