Struct Letterbox 

#[non_exhaustive]
pub struct Letterbox {
    pub placement: Option<LetterboxPlacement>,
    pub pad: Option<Vec<f32>>,
    pub pad_space: Option<PadSpace>,
}

Letterbox geometry for resize: letterbox.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

placement: Option<LetterboxPlacement>

Where the scaled image sits inside the input. Absent means centred.

pad: Option<Vec<f32>>

Per-channel pad value, in the space named by pad_space. Absent means 114 per channel in pixel space.

pad_space: Option<PadSpace>

Space pad is expressed in. Absent means pixel space.
