Struct MaskPipeline 

pub struct MaskPipeline { /* private fields */ }

An ordered mask processing pipeline.

Implementations

impl MaskPipeline

pub fn new() -> Self

Create an empty mask pipeline.

pub fn is_empty(&self) -> bool

Return whether the pipeline has no operations.

pub fn operations(&self) -> &[MaskOperation]

Return the ordered operations in this pipeline.

pub fn blur_with(self, sigma: f32) -> Self

Add a blur operation with a custom sigma.

Panics

Panics if sigma is not greater than zero.

pub fn threshold_with(self, value: u8) -> Self

Add a threshold operation with a custom value.

pub fn dilate_with(self, radius: f32) -> Self

Add a dilation operation with a custom radius.

A radius of zero leaves the mask unchanged.

Panics

Panics if radius is negative or NaN.

pub fn erode_with(self, radius: f32) -> Self

Add an erosion operation with the default boundary behavior.

A radius of zero leaves the mask unchanged.

Panics

Panics if radius is negative or NaN.

pub fn erode_with_border_mode( self, radius: f32, border_mode: ErosionBorderMode, ) -> Self

Add an erosion operation with a custom radius and boundary behavior.

A radius of zero leaves the mask unchanged.

Panics

Panics if radius is negative or NaN.

pub fn fill_holes_with(self, threshold: u8) -> Self

Add a hole-filling operation with a custom threshold.

pub fn keep_largest_component(self) -> Self

Keep only the largest connected foreground component.

pub fn keep_n_largest_components(self, count: usize) -> Self

Keep the largest count connected foreground components.

pub fn drop_components_below_area(self, min_area: f32) -> Self

Drop connected foreground components below min_area pixels.

Panics

Panics if min_area is negative or NaN.

Trait Implementations

impl Clone for MaskPipeline

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaskPipeline

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

Formats the value using the given formatter.

impl Default for MaskPipeline

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for MaskPipeline

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
