隐藏控制台窗口

在做opencv实验的时候发现了一个十分有趣的东西，那就是通过使用#pragma命令可以使那个“黑黢黢”的控制台窗口隐藏

//隐藏控制台窗口
#pragma comment(linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"")

//缩放图像文件

#include <opencv2/opencv.hpp>
using namespace std;

//隐藏控制台窗口
#pragma comment(linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"")

int main()
{
	const char *pstrImageName = "冲浪大师赛001.jpg";
	const char *pstrSaveImageName = "冲浪大师赛001缩放图.jpg";
	const char *pstrWindowsSrcTitle = "原图";
	const char *pstrWindowsDstTitle = "缩放图";

	double fScale = 0.314;		//缩放倍数
	CvSize czSize;			    //目标图像尺寸

	//从文件中读取图像  
	IplImage *pSrcImage = cvLoadImage(pstrImageName, CV_LOAD_IMAGE_UNCHANGED);
	IplImage *pDstImage = NULL;	

	//计算目标图像大小
	czSize.width = pSrcImage->width * fScale;
	czSize.height = pSrcImage->height * fScale;

	//创建图像并缩放
	pDstImage = cvCreateImage(czSize, pSrcImage->depth, pSrcImage->nChannels);
	cvResize(pSrcImage, pDstImage, CV_INTER_AREA);

	//创建窗口
	cvNamedWindow(pstrWindowsSrcTitle, CV_WINDOW_AUTOSIZE);
	cvNamedWindow(pstrWindowsDstTitle, CV_WINDOW_AUTOSIZE);

	//在指定窗口中显示图像
	cvShowImage(pstrWindowsSrcTitle, pSrcImage);
	cvShowImage(pstrWindowsDstTitle, pDstImage);

	//等待按键事件
	cvWaitKey();

	//保存图片
	cvSaveImage(pstrSaveImageName, pDstImage);

	cvDestroyWindow(pstrWindowsSrcTitle);
	cvDestroyWindow(pstrWindowsDstTitle);
	cvReleaseImage(&pSrcImage);
	cvReleaseImage(&pDstImage);
	return 0;
