Static Methods

allocateFloat32(int elements) → Float32List

Allocates a contiguous Float32List of specified elements.

allocateUint8(int bytes) → Uint8List

Allocates a contiguous Uint8List of specified bytes.

copyUint8(Uint8List source, Uint8List destination, {int sourceOffset = 0, int destinationOffset = 0, int? length}) → void

Fast memory copy from source Uint8List to target Uint8List.

rgbaToRgb(Uint8List rgbaBuffer, int width, int height) → Uint8List

Converts an RGBA byte buffer to a 3-channel RGB buffer.

rgbToGrayscale(Uint8List rgbBuffer, int width, int height) → Uint8List

Converts an RGB byte buffer to a 1-channel Grayscale buffer using standard luminance. (Luminance = 0.299 * R + 0.587 * G + 0.114 * B)
