Struct ConvertOptions 

pub struct ConvertOptions { /* private fields */ }

Options for convert. The default converts the whole source, stretched, with no rotation or flip, and maps pixels as Normalization::unsigned for float destinations.

let opts = ConvertOptions::new()
    .letterbox([0, 0, 0, 255])
    .placement(LetterboxPlacement::TopLeft)
    .pad_output([0.0; 4])
    .normalization(Normalization::imagenet())
    .rotation(Rotation::None);

Implementations

impl ConvertOptions

pub fn new() -> Self

The default options.

pub fn rotation(self, rotation: Rotation) -> Self

Rotate the output, in 90° steps.

pub fn flip(self, flip: Flip) -> Self

Flip the output.

pub fn crop(self, crop: Crop) -> Self

Set the source region and fit together.

pub fn source(self, source: Option<Region>) -> Self

Sample only source of the input; None samples all of it.

pub fn letterbox(self, pad: [u8; 4]) -> Self

Letterbox: keep the source aspect ratio and pad the rest with the RGBA pixel pad, which is mapped like the image.

pub fn placement(self, placement: LetterboxPlacement) -> Self

Where a letterboxed image sits. Ignored without a letterbox fit.

pub fn pad_output(self, pad: [f32; 4]) -> Self

Pad with these values as written to the destination (after normalization; quantized for integer destinations), instead of mapping the pixel pad. Ignored without a letterbox fit.

pub fn normalization(self, normalization: impl Into<Normalization>) -> Self

How pixel values map to the destination.

pub fn get_rotation(&self) -> Rotation

The output rotation.

pub fn get_flip(&self) -> Flip

The output flip.

pub fn get_crop(&self) -> Crop

The source region and fit.

pub fn get_placement(&self) -> LetterboxPlacement

The letterbox placement.

pub fn get_pad_output(&self) -> Option<[f32; 4]>

The output-domain pad, when set.

pub fn get_normalization(&self) -> Normalization

The pixel value mapping.
