A device CMYK color: the amounts of cyan, magenta, yellow and black inks, without color profile.

public readonly struct Cmyk : IEquatable<Cmyk>

Remarks

The conversions are the naive ones of CSS Color 5 (device-cmyk()), on the encoded RGB values as they are: the black is what the three inks share (full gray component replacement), and the inks do not interact. They do not describe what a press prints: an image of CMYK samples is converted with its ICC profile (CmykConversionOptions), and colors with IccColorTransform.

The values are not validated: the conversion to RGB clips each component to [0, 1].

Methods

NameDescription
Equals(Cmyk)Indicates whether the current object is equal to another object of the same type.
Equals(object?)Indicates whether this instance and a specified object are equal.
FromRgb(Rgba32)Converts an 8-bit RGB color to device CMYK. Alpha is ignored.
FromRgb(Rgba64)Converts a 16-bit RGB color to device CMYK. Alpha is ignored.
GetHashCode()Returns the hash code for this instance.
ToRgba32()Converts this color to an opaque 8-bit RGB color, each component clipped to [0, 1].
ToRgba64()Converts this color to an opaque 16-bit RGB color, each component clipped to [0, 1].
ToString()Returns the fully qualified type name of this instance.

Equals overloads

Equals(Cmyk)

Cmyk.cs

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

public bool Equals(Cmyk other)
Parameters
other Cmyk
An object to compare with this object.
Returns

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

Equals(object?)

Cmyk.cs

Indicates whether this instance and a specified object are equal.

public override bool Equals(object? obj)
Parameters
obj object?
The object to compare with the current instance.
Returns

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