  Converts a channel to the [0, 255] range.
Returns number
- Defined in src/gif/Color.ts:17

`Static`rgb8

rgb8(red: number, green: number, blue: number): number
Constructs a color from individual channels ranging from 0 to 255.
Parameters
- red: number
- green: number
- blue: number
Returns number
- Defined in src/gif/Color.ts:36

`Static`rgb

rgb(red: number, green: number, blue: number): number
Constructs a color from individual channels ranging from 0 to 1.
Parameters
- red: number
- green: number
- blue: number
Returns number
- Defined in src/gif/Color.ts:41

`Static`hsv

hsv(hue: number, saturation: number, value: number): number
Constructs a color from HSV values ranging from 0 to 1.
Parameters
- hue: number
- saturation: number
- value: number
Returns number
- Defined in src/gif/Color.ts:46

`Static`toHexString

toHexString(color: number): string
Encodes a color as a hexadecimal string, like #abcdef.
Parameters

`Static`bytesToColorArray

bytesToColorArray(
    length: number,
    bytes: CouldBeIterable<number>,
    order?: string,
    endianness?: "big" | "little",
): { colors: Uint32Array; filledPixels: number; fullyFilled: boolean }
Interprets an array of bytes into colors.
Parameters
- length: number
- bytes: CouldBeIterable<number>
- order: string = 'RGB_'
  Swizzling order of bytes. Letters that don't correspond to any channel cause that byte to be ignored. Valid channels are R/r for red, G/g for green, and B/b for blue.
- endianness: "big" | "little" = 'big'
  In big-endian mode, the first byte is the most significant, while in little-endian mode, it's the least significant.
Returns { colors: Uint32Array; filledPixels: number; fullyFilled: boolean }
- Defined in src/gif/Color.ts:76

`Static`imageDataToColors

imageDataToColors(imageData: ImageData): Uint32Array
Parameters
- imageData: ImageData
Returns Uint32Array
- Defined in src/gif/Color.ts:155
