How to use the @tensorflow-models/posenet.singlePose function in @tensorflow-models/posenet

export function drawOffsetVectors(
  heatMapValues, offsets, outputStride, scale = 1, ctx) {
  const offsetPoints = posenet.singlePose.getOffsetPoints(
    heatMapValues, outputStride, offsets);

  const heatmapData = heatMapValues.buffer().values;
  const offsetPointsData = offsetPoints.buffer().values;

  for (let i = 0; i < heatmapData.length; i += 2) {
    const heatmapY = heatmapData[i] * outputStride;
    const heatmapX = heatmapData[i + 1] * outputStride;
    const offsetPointY = offsetPointsData[i];
    const offsetPointX = offsetPointsData[i + 1];

    drawSegment([heatmapY, heatmapX], [offsetPointY, offsetPointX],
      color, scale, ctx);
  }
}
