方法1

	g_savedPoints.resize(pResult->contourData.contourPointCount);
	//方法1
	std::copy(pResult->contourData.pointArray, pResult->contourData.pointArray + pResult->contourData.contourPointCount, g_savedPoints.begin());

方法2

	g_savedPoints.resize(pResult->contourData.contourPointCount);
	//方法2
	memcpy(g_savedPoints.data(), pResult->contourData.pointArray, pResult->contourData.contourPointCount * sizeof(FloatPoint));

以上两种方法都要注意，用之前要重定义确定容器大小：

	g_savedPoints.resize(pResult->contourData.contourPointCount);
