Enum EdgeMode

pub enum EdgeMode {
    Clamp = 0,
    Wrap = 1,
    Reflect = 2,
    Reflect101 = 3,
    Constant = 4,
}

Declares an edge handling mode

Variants

Clamp = 0

If kernel goes out of bounds it will be clipped to an edge and edge pixel replicated across filter

Wrap = 1

If kernel goes out of bounds it will be clipped, this is a slightly faster than clamp, however have different visual effects at the edge.

Reflect = 2

If filter goes out of bounds image will be replicated with rule fedcba|abcdefgh|hgfedcb.

Reflect101 = 3

If filter goes out of bounds image will be replicated with rule gfedcb|abcdefgh|gfedcba.

Constant = 4

If filter goes out of bounds image will be replicated with provided constant. Works only for filter APIs.

Trait Implementations

impl Clone for EdgeMode

fn clone(&self) -> EdgeMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeMode

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

Formats the value using the given formatter.

impl Default for EdgeMode

fn default() -> EdgeMode

Returns the “default value” for a type.

impl From<usize> for EdgeMode

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Ord for EdgeMode

fn cmp(&self, other: &EdgeMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EdgeMode

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

impl PartialOrd for EdgeMode

fn partial_cmp(&self, other: &EdgeMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
