Struct ZoomSegment 

pub struct ZoomSegment {
    pub id: ZoomId,
    pub start: Frame,
    pub end: Frame,
    pub amount: f64,
    pub mode: ZoomMode,
    pub ease: EditEase,
}

A cinematic punch-in over [start, end) project frames.

Fields

id: ZoomId

Stable identifier within the project.

start: Frame

First project frame the zoom affects (inclusive).

end: Frame

One past the last project frame the zoom affects (exclusive).

amount: f64

Zoom factor at the hold. 1.0 = no zoom, 1.6 = 1.6× punch-in. A zoom out is unusual for a screen recording, so the zoom engine (crate::zoom_anim::zoom_at) clamps the produced scale to >= 1.0 — an amount < 1.0 reads as no zoom rather than a shrink.

mode: ZoomMode

What the zoom targets.

ease: EditEase

Easing of the in/out animation.

Implementations

impl ZoomSegment

pub fn manual(id: ZoomId, start: Frame, end: Frame, amount: f64) -> Self

A manual, centre-targeted zoom of amount over [start, end) with the default Easy-Ease curve.

pub fn len(self) -> Frame

Length of the zoom window in project frames (saturating at 0).

pub fn is_empty(self) -> bool

Whether the zoom window is empty (end <= start).

pub fn contains(self, project_frame: Frame) -> bool

Whether project_frame falls within this zoom’s window.

Trait Implementations

impl Clone for ZoomSegment

fn clone(&self) -> ZoomSegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZoomSegment

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ZoomSegment

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ZoomSegment

fn eq(&self, other: &ZoomSegment) -> 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 Serialize for ZoomSegment

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ZoomSegment

impl StructuralPartialEq for ZoomSegment
