normalizeBuffer method

Future<NormalizedImage?> normalizeBuffer(Uint8List bytes, int width, int height, int stride, int format, dynamic points, int rotation, ColorMode color,)

Normalize documents. bytes - bytes of the image. width - width of the image. height - height of the image. stride - stride of the image. format - format of the image. points - points of the document. Returns a NormalizedImage.
