Struct Comp 

pub struct Comp {
    pub canvas: Canvas,
    pub layers: Vec<CompLayer>,
    pub project: Arc<CompProject>,
    /* private fields */
}

A composition: a canvas and layers, bottom first.

Fields

canvas: Canvas

layers: Vec<CompLayer>

project: Arc<CompProject>

Shared with nested comps.

Implementations

impl Comp

pub fn frames(&self) -> i64

Frames in the comp.

pub fn span(&self, layer: &CompLayer) -> Range<i64>

Comp frames where layer shows.

pub fn pieces(&self) -> Vec<Range<i64>>

Pieces of the comp, cut at layer in/out points, none shorter than a second (unless the comp is).

pub fn lower( &self, range: Range<i64>, out: Size, media: &dyn Media, ) -> Result<Piece>

Lowers comp frames range for a render of out px (lengths scale by out/canvas).

impl Comp

pub fn from_file(path: &Path) -> Result<Self>

Reads NAME.comp.json or NAME.comp.yaml; relative media paths resolve against its directory.

pub fn from_value(v: &Value, dir: &Path) -> Result<Self>

Reads a comp document; dir resolves relative media paths.
