Rgba64 Struct

Namespace: Meziantou.Framework.Imaging
Assembly: Meziantou.Framework.Imaging.dll
Package: Meziantou.Framework.Imaging 1.2.11
Source: Rgba64.cs
Available in package assets: net10.0net11.0

A pixel with 16-bit red, green, blue and straight (non-premultiplied) alpha components.

public struct Rgba64 : IEquatable<Rgba64>

Remarks

Components are stored as UInt16 values in native endianness. Codecs convert from/to the endianness of the encoded format; raw byte access (ImageFrame.CopyPixelBytesTo) exposes native-endian values.

Implements

IEquatable<Rgba64>

Constructors

Name	Description
Rgba64(ushort, ushort, ushort, ushort)	Initializes a new instance of the `Rgba64` struct.

Rgba64(ushort, ushort, ushort, ushort)

Rgba64.cs

Initializes a new instance of the Rgba64 struct.

public Rgba64(ushort r, ushort g, ushort b, ushort a = 65535)

Parameters

r ushort: The red component.
g ushort: The green component.
b ushort: The blue component.
a ushort: The straight alpha component. Defaults to fully opaque.

Methods

Name	Description
Equals(Rgba64)	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.
FromRgba32(Rgba32)	Creates an `Rgba64` from an `Rgba32` using exact full-range expansion (`v * 257`).
GetHashCode()	Returns the hash code for this instance.
ToString()	Returns the fully qualified type name of this instance.

Equals overloads

Equals(Rgba64)

Rgba64.cs

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

public readonly bool Equals(Rgba64 other)

Parameters

other Rgba64: An object to compare with this object.

Returns

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

Equals(object?)

Rgba64.cs

Indicates whether this instance and a specified object are equal.

public override readonly 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.

FromRgba32(Rgba32)

Rgba64.cs

Creates an Rgba64 from an Rgba32 using exact full-range expansion (v * 257).

public static Rgba64 FromRgba32(Rgba32 value)

Parameters

value Rgba32: The 8-bit pixel.

Returns

Rgba64 The widened pixel.

GetHashCode()

Rgba64.cs

Returns the hash code for this instance.

public override readonly int GetHashCode()

Returns

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

ToString()

Rgba64.cs

Returns the fully qualified type name of this instance.

public override readonly string ToString()

Returns

string The fully qualified type name.

Operators

Name	Description
operator ==(Rgba64, Rgba64)	Compares two pixels for equality.
operator !=(Rgba64, Rgba64)	Compares two pixels for inequality.

operator ==(Rgba64, Rgba64)

Rgba64.cs

Compares two pixels for equality.

public static bool operator ==(Rgba64 left, Rgba64 right)

Parameters

left Rgba64: The first pixel.
right Rgba64: The second pixel.

Returns

bool true if all components are equal; otherwise false.

operator !=(Rgba64, Rgba64)

Rgba64.cs

Compares two pixels for inequality.

public static bool operator !=(Rgba64 left, Rgba64 right)

Parameters

left Rgba64: The first pixel.
right Rgba64: The second pixel.

Returns

bool true if any component differs; otherwise false.
