Bgr565 Struct

Namespace: Meziantou.Framework.Imaging
Assembly: Meziantou.Framework.Imaging.dll
Package: Meziantou.Framework.Imaging 1.2.11
Source: Bgr565.cs
Available in package assets: net10.0net11.0

An opaque pixel with a 5-bit red, a 6-bit green and a 5-bit blue component, packed in a 16-bit value.

public struct Bgr565 : IEquatable<Bgr565>

Remarks

Bgr565.PackedValue is stored in native endianness and holds blue in its 5 low bits, green in the next 6 bits and red in its 5 high bits: the layout of DXGI_FORMAT_B5G6R5_UNORM and of the RGB_565 bitmaps of Android. The components go from 0 to 31 (red and blue) or 63 (green), the largest value of their bits.

A component is the fraction of its largest value: conversions to and from the other formats round to the nearest sample, so the conversion to a format with 8 bits or more per component and back is exact, and a conversion to this format reduces the precision.

Equals overloads

Equals(Bgr565)

Bgr565.cs

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

public readonly bool Equals(Bgr565 other)

Parameters

other Bgr565: An object to compare with this object.

Returns

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

Equals(object?)

Bgr565.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.

GetHashCode()

Bgr565.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()
