Struct Animation 

pub struct Animation {
    pub in_: Option<Anim>,
    pub out: Option<Anim>,
    pub position: Keys<2>,
    pub scale: Keys<2>,
    pub opacity: Keys<1>,
    pub colour: Keys<4>,
}

A clip’s animation: its entrance, exit and keyframed parameters.

Fields

in_: Option<Anim>

out: Option<Anim>

position: Keys<2>

Absolute position (fractions of the frame from its middle).

scale: Keys<2>

Scale about the anchor, [x, y].

opacity: Keys<1>

Multiplies the alpha.

colour: Keys<4>

Replaces the text’s colour.

Implementations

impl Animation

pub fn parse(m: &Map<String, Value>) -> Self

From merged clip parameters: animation.{in,out} (else fade_in / fade_out) and keyframes.{position,scale,opacity,colour}.

pub fn is_plain_fade(&self) -> bool

Whether the overlay’s own linear fades draw it (no motion needed).

pub fn raster_scale(&self) -> f32

The largest scale keyframed (at least 1, at most 4): rasterise at it so the text stays sharp. An expression scale is read at the clip’s start only: use Animation::raster_scale_over when the clip’s length is known.

pub fn raster_scale_over(&self, len: f64, fps: f64) -> f32

Animation::raster_scale for a clip len seconds long at fps: an expression scale is sampled on every frame.

Trait Implementations

impl Clone for Animation

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Animation

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

Formats the value using the given formatter.

impl Default for Animation

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Animation

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

Equality operator ==.

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

Inequality operator !=.
