Enum Rotation 

pub enum Rotation {
    Deg0,
    Deg90,
    Deg180,
    Deg270,
}

Clockwise rotation to apply when displaying a frame.

This is the convention of the WebCodecs VideoFrame.rotation. A binding whose source states rotation another way converts it: FFmpeg’s display matrix angle is counter-clockwise, so a binding reports (-angle) mod 360.

Variants

Deg0

No rotation.

Deg90

Clockwise quarter turn.

Deg180

Half turn.

Deg270

Clockwise three-quarter turn, i.e. a counter-clockwise quarter turn.

Implementations

impl Rotation

pub const fn quarter_turns(self) -> u32

Clockwise quarter turns, 0..4.

pub const fn from_quarter_turns(quarter_turns: i32) -> Self

The rotation of quarter_turns clockwise quarter turns, of any sign.

pub const fn swaps_axes(self) -> bool

Whether the rotation exchanges width and height.
