Struct Color32

Namespace
LMKit.Graphics.Primitives
Assembly
LM-Kit.NET.dll

Immutable 32-bit color value with 8-bit R, G, B, and A channels.

public readonly struct Color32 : IEquatable<Color32>
Implements
Inherited Members

Examples

// Opaque white
var white = new Color32(255, 255, 255);

// Semi-transparent red
var red50 = new Color32(255, 0, 0, 128);

// Pack/unpack RRGGBBAA
int rgba = red50.ToRgba();          // 0xFF000080
var again = Color32.FromRgba(rgba); // equal to red50

Remarks

Each component is stored as a byte in the range 0..255.

Packed integer format: 0xRRGGBBAA (alpha in the least significant byte).

Use ToRgba() and FromRgba(int) for round-trips.

Constructors

Color32(byte)

Initializes a new opaque Color32 from a single grayscale value.

Color32(byte, byte, byte)

Initializes a new opaque Color32 from red, green, and blue components (alpha=255).

Color32(byte, byte, byte, byte)

Initializes a new Color32 from red, green, blue, and alpha components.

Fields

A

Alpha channel (0..255). 0=fully transparent, 255=fully opaque.

B

Blue channel intensity (0..255).

G

Green channel intensity (0..255).

R

Red channel intensity (0..255).

Methods

Deconstruct(out byte, out byte, out byte, out byte)

Deconstructs the color into (r, g, b, a).

Equals(Color32)
Equals(object)
FromBgr(int)

Creates an opaque Color32 from a packed 24-bit BGR integer (0xBBGGRR).

FromBgr(int, byte)

Creates a Color32 from a packed 24-bit BGR integer (0xBBGGRR) and an alpha.

FromRgb(int)

Creates an opaque Color32 from a packed 24-bit RGB integer (0xRRGGBB).

FromRgb(int, byte)

Creates a Color32 from a packed 24-bit RGB integer (0xRRGGBB) and an alpha.

FromRgba(int)

Creates a Color32 from a packed 32-bit RGBA integer (0xRRGGBBAA).

GetHashCode()
GetLuminance()

Computes the perceived brightness (luminance) of this color as a single 8-bit grayscale value. Uses Rec. 601 luma weights: 0.299 * R + 0.587 * G + 0.114 * B.

ToRgb()

Converts this color to a packed 24-bit RGB integer (0xRRGGBB), dropping alpha.

ToRgba()

Converts this color to a packed 32-bit RGBA integer (0xRRGGBBAA).

ToString()
WithAlpha(byte)

Returns a copy of this color with a different alpha.

Operators

operator ==(Color32, Color32)
operator !=(Color32, Color32)
