Struct Crop 

pub struct Crop {
    pub source: Option<Region>,
    pub fit: Fit,
}

Source-side convert geometry: which sub-rectangle of the source to sample (source) and how to fit it into the destination (fit). Destination placement is the destination itself — a tensor, or a Region view / batch tile of one — not a field here.

Fields

source: Option<Region>

Sub-rectangle of the source to sample. None samples the whole source.

fit: Fit

How the source is fit into the destination shape.

Implementations

impl Crop

pub fn new() -> Self

A no-op crop: whole source, stretched to fill the whole destination.

pub fn no_crop() -> Self

Alias for Crop::new — whole source, stretch to fill.

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

Letterbox fit: preserve the source aspect ratio, padding the remainder with pad (RGBA).

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

Sample only source of the input (builder).

pub fn with_fit(self, fit: Fit) -> Self

Set the fit mode (builder).

pub fn check_crop_dyn( &self, src: &TensorDyn, dst: &TensorDyn, ) -> Result<(), Error>

Validate against TensorDyn source and destination dimensions.

Trait Implementations

impl Clone for Crop

fn clone(&self) -> Crop

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Crop

impl Debug for Crop

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

Formats the value using the given formatter.

impl Default for Crop

fn default() -> Crop

Returns the “default value” for a type.

impl Eq for Crop

impl PartialEq for Crop

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