Enum AnimFrameMode 

pub enum AnimFrameMode {
    Auto,
    Delta,
    Lossless,
}

How a single animation frame’s pixels are compressed into its ANMF “Frame Data” bitstream subchunk.

Reproduces the published-0.1.5 variant set. All three modes are wired in this build; the round-127 Auto and Delta paths encode the caller’s full-canvas frame as a lossless dirty-rect sub-frame against the previous canvas (the original lossy keyframe vs. inter-frame delta choice is deferred until the oxideav-vp8 lossy encoder is ready, at which point Auto will also evaluate a lossy candidate).

Variants

Auto

Evaluate both the full-canvas VP8L keyframe and the dirty-rect VP8L sub-frame and emit whichever is smaller. Falls back to the full-canvas keyframe for the first frame and for frames whose dirty rect happens to cover the whole canvas.

Delta

Always emit the dirty-rect sub-frame (the §2.7.1.1 B = 1 / D = 0 overwrite-no-dispose path). First frame is always the full canvas.

Lossless

Encode the frame as a standalone §2.6 VP8L lossless keyframe.

Trait Implementations

impl Clone for AnimFrameMode

fn clone(&self) -> AnimFrameMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AnimFrameMode

impl Debug for AnimFrameMode

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

Formats the value using the given formatter.

impl Default for AnimFrameMode

fn default() -> AnimFrameMode

Returns the “default value” for a type.

impl Eq for AnimFrameMode

impl PartialEq for AnimFrameMode

fn eq(&self, other: &AnimFrameMode) -> 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.
