C++内存复制

方法1

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

方法2

	g_savedPoints.resize(pResult->contourData.contourPointCount);//方法2memcpy(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);
