Methods

Equals(CieLch)

Indicates whether the current object is equal to another object of the same type.

Declaration

public bool Equals(CieLch other)

Parameters

Type	Name	Description
CieLch	other	An object to compare with this object.

Returns

Type	Description
bool	true if the current object is equal to the other parameter; otherwise, false.

Equals(object?)

Indicates whether this instance and a specified object are equal.

Declaration

public override bool Equals(object? obj)

Parameters

Type	Name	Description
object	obj	The object to compare with the current instance.

Returns

Type	Description
bool	true if obj and this instance are the same type and represent the same value; otherwise, false.

Overrides

ValueType.Equals(object)

GetHashCode()

Returns the hash code for this instance.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	A 32-bit signed integer that is the hash code for this instance.

Overrides

ValueType.GetHashCode()

Saturation()

Computes the saturation of the color (chroma normalized by lightness)

Declaration

public float Saturation()

Returns

Type	Description
float	The float

Remarks

A value ranging from 0 to 100.

ToString()

Returns the fully qualified type name of this instance.
