隱藏控製台窗口
在做opencv實驗的時候發現了一個十分有趣的東西，那就是通過使用#pragma命令可以使那個“黑黢黢”的控製台窗口隱藏
//隱藏控製台窗口 #pragma comment(linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"")
//縮放圖像文件
#include <opencv2/opencv.hpp>
using namespace std;
//隱藏控製台窗口
#pragma comment(linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"")
int main()
{
const char *pstrImageName = "衝浪大師賽001.jpg";
const char *pstrSaveImageName = "衝浪大師賽001縮放圖.jpg";
const char *pstrWindowsSrcTitle = "原圖";
const char *pstrWindowsDstTitle = "縮放圖";
double fScale = 0.314; //縮放倍數
CvSize czSize; //目標圖像尺寸
//從文件中讀取圖像
IplImage *pSrcImage = cvLoadImage(pstrImageName, CV_LOAD_IMAGE_UNCHANGED);
IplImage *pDstImage = NULL;
//計算目標圖像大小
czSize.width = pSrcImage->width * fScale;
czSize.height = pSrcImage->height * fScale;
//創建圖像並縮放
pDstImage = cvCreateImage(czSize, pSrcImage->depth, pSrcImage->nChannels);
cvResize(pSrcImage, pDstImage, CV_INTER_AREA);
//創建窗口
cvNamedWindow(pstrWindowsSrcTitle, CV_WINDOW_AUTOSIZE);
cvNamedWindow(pstrWindowsDstTitle, CV_WINDOW_AUTOSIZE);
//在指定窗口中顯示圖像
cvShowImage(pstrWindowsSrcTitle, pSrcImage);
cvShowImage(pstrWindowsDstTitle, pDstImage);
//等待按鍵事件
cvWaitKey();
//保存圖片
cvSaveImage(pstrSaveImageName, pDstImage);
cvDestroyWindow(pstrWindowsSrcTitle);
cvDestroyWindow(pstrWindowsDstTitle);
cvReleaseImage(&pSrcImage);
cvReleaseImage(&pDstImage);
return 0;
}
