Windows网络编程_练习题参考答案

对Windows网络编程的练习题有详细的讲解，课后习题基本上都有答案。

TestImage game

// TestImage.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include "cv.h" #include "highgui.h" int main( int argc, char** argv )//argc说明参数的个数，argv的值是一个char*的值 { IplImage* pImg1; //声明IplImage指针 IplImage* pImg2; //载入图像 // if( argc == 2 && // (pImg = cvLoadImage( argv[1], 1)) != 0 )//[[此处的argc==2是否需要改成argc==1？我改了之后才能运行成功。求大牛解惑]] // wmzzzz : 在"属性"|"debug"|里的command arguments 里加入参数(一个路径:要打开的文件路径) 这时 argc==2 就合理了...可以试试多加几个 // { pImg1 = cvLoadImage("Tulips.jpg");//修改5*5个像素点 pImg2 = cvLoadImage("Chrysanthemum.jpg"); for(int i=10;i<100;i++) { for(int j=50;j<125;j++) { CV_IMAGE_ELEM( pImg2, uchar, i, j*3 + 0 )=CV_IMAGE_ELEM( pImg1, uchar, i, j*3 + 0 )/2+CV_IMAGE_ELEM( pImg2, uchar, i, j*3 + 0 )/2; CV_IMAGE_ELEM( pImg2, uchar, i, j*3 + 1 )=CV_IMAGE_ELEM( pImg1, uchar, i, j*3 + 1 )/2+CV_IMAGE_ELEM( pImg2, uchar, i, j*3 + 1 )/2; CV_IMAGE_ELEM( pImg2, uchar, i, j*3 + 2 )=CV_IMAGE_ELEM( pImg1, uchar, i, j*3 + 2 )/2+CV_IMAGE_ELEM( pImg2, uchar, i, j*3 + 2 )/2; } } cvNamedWindow( "Image", 1 );//创建窗口 cvShowImage( "Image", pImg1 );//显示图像 cvNamedWindow( "Image", 1 );//创建窗口 cvShowImage( "Image", pImg2);//显示图像 cvWaitKey(0); //等待按键 cvDestroyWindow( "Image" );//销毁窗口 cvReleaseImage( &pImg1;); //释放图像 cvWaitKey(0); //等待按键 cvDestroyWindow( "Image" );//销毁窗口 cvReleaseImage( &pImg2;); //释放图像 return 0; }
