Struct MaskProcessingOptions 

pub struct MaskProcessingOptions {
    pub binary: bool,
    pub blur: bool,
    pub blur_sigma: f32,
    pub mask_threshold: u8,
    pub dilate: bool,
    pub dilation_radius: f32,
    pub fill_holes: bool,
}

Configuration for mask post-processing operations.

Defines the pipeline of blur, threshold, dilation, and hole-filling operations applied to raw mattes. Used as defaults in Outline and can be overridden per operation via MatteHandle and MaskHandle.

Explicit Configuration

This struct does not apply automatic logic. For example, setting dilate = true or fill_holes = true will not automatically enable binary. If you need a binary mask for dilation or hole-filling to work meaningfully, you must explicitly set binary = true or call threshold in your processing chain.

Note: The CLI’s --binary auto mode does automatically enable thresholding when --dilate or --fill-holes is specified. The library leaves this decision to you for maximum control and predictability.

Fields

binary: bool

Whether to apply binary thresholding to the mask.

blur: bool

Whether to apply Gaussian blur to the mask.

blur_sigma: f32

Standard deviation (sigma) for Gaussian blur.

mask_threshold: u8

Threshold value (0–255) used for binary conversion and hole-filling.

dilate: bool

Whether to dilate the mask using a Euclidean distance transform.

dilation_radius: f32

Radius in pixels for the dilation operation.

fill_holes: bool

Whether to fill interior holes in the binary mask.

Trait Implementations

impl Clone for MaskProcessingOptions

fn clone(&self) -> MaskProcessingOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaskProcessingOptions

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

Formats the value using the given formatter.

impl Default for MaskProcessingOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for MaskProcessingOptions

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