Struct ResizeOptions 

#[non_exhaustive]
pub struct ResizeOptions {
    pub filter: Filter,
    pub fit: Fit,
    pub without_enlargement: bool,
    pub without_reduction: bool,
    pub position: Position,
    pub background: [u8; 4],
}

Options for Resize.

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.

filter: Filter

The resampling filter. Defaults to Filter::Lanczos3.

fit: Fit

How the target box is interpreted.

without_enlargement: bool

Never scale up: an image already smaller than the box is left alone.

without_reduction: bool

Never scale down: an image already larger than the box is left alone (sharp’s withoutReduction).

position: Position

Which part Fit::Cover keeps and where Fit::Contain places the image. Centred by default, as in sharp.

background: [u8; 4]

The RGBA colour Fit::Contain pads with: opaque black by default, as in sharp. Grey formats take its luma; formats without alpha ignore its alpha.
