opencv 批量更改图片大小

注意不要引发 ssize.area()>0 的错误 ，操作之前需要先将图片id统一下

//批量更改图片大小
#include<iostream>
#include<stdio.h>
#include<opencv2\opencv.hpp>
#include<string>

using namespace std;
using namespace cv;

int main()
{
	Mat src;
	string path1 = "..\\posdata\\";
	string path2 = "..\\posdata2\\";
	string pp=".jpg";

	for (int i = 1; i < 15; i++)
	{
		string c;
		c = to_string(i);
		string path = path1 + c + pp;
		src = imread(path, 1);
		resize(src, src, Size(60,60));

		string pathh = path2 + c + pp;
		imwrite(pathh,src);
	}

	return 0;
}
