Alpha融合菜单项
1. 增加alpha融合菜单项,修改相应的属性,建立类向导,编辑消息处理函数。
2. 在消息处理函数中添加如下代码
void CCVMFCView::OnAlphaMix()
{
//TODO: Add your command handler code here
//TODO: Add your command handler code here
IplImage*src1, *src2;
CStringcsAVI="src1 Files(lena.bmp)|*.bmp|";
CString csFilter=csAVI;
CStringcsFilter2="src2 Files(gs76.bmp)|*.bmp|";
CStringname[]={"","bmp",""};
CStringstrFileName;
CStringstrExtension;
CFileDialogFileDlg(true,NULL,NULL,OFN_HIDEREADONLY,csFilter);
if(FileDlg.DoModal()==IDOK ) { // 选择了文件名
strFileName= FileDlg.m_ofn.lpstrFile;
if(FileDlg.m_ofn.nFileExtension == 0) { // 无文件后缀
strExtension= name[FileDlg.m_ofn.nFilterIndex];
strFileName= strFileName + '.' + strExtension;
// 加文件后缀
}
src1=cvLoadImage(strFileName);
if(src1)
{
MessageBox("还需要打开一张图片!");
}
CFileDialog FileDlg(true,NULL,NULL,OFN_HIDEREADONLY,csFilter2);
if(FileDlg.DoModal()==IDOK ) { // 选择了文件名
strFileName= FileDlg.m_ofn.lpstrFile;
if(FileDlg.m_ofn.nFileExtension == 0) { // 无文件后缀
strExtension= name[FileDlg.m_ofn.nFilterIndex];
strFileName= strFileName + '.' + strExtension;
// 加文件后缀
}
src2=cvLoadImage(strFileName);
cvNamedWindow("src1",CV_WINDOW_AUTOSIZE);
cvMoveWindow("src1",300,300);
cvShowImage("src1",src1);
cvNamedWindow("src2",CV_WINDOW_AUTOSIZE);
cvMoveWindow("src2",300+src1->width,300);
cvShowImage("src2",src2);
intx = 112;
int y = 123;
int width =src2->width;
int height =src2->height;
double alpha = 0.5;
double beta = 1-alpha;
cvSetImageROI(src1, cvRect(x,y,width,height));
cvSetImageROI(src2, cvRect(0,0,width,height));
cvAddWeighted(src1, alpha, src2, beta,0.0,src1);
cvResetImageROI(src1);
cvNamedWindow( "Alpha_blend",CV_WINDOW_AUTOSIZE );
cvMoveWindow("Alpha_blend",350+src1->width+src2->width,300);
cvShowImage( "Alpha_blend", src1 );
cvWaitKey(0);
cvReleaseImage(&src1);
cvReleaseImage(&src2);
}
}
}
播放wav音乐
1.插入资源(插入->资源->定制->(输入WAVA))
2.在resources中找到"WAVA"文件,打开有个IDR_WAVA1
3.右键->import->浏览后缀名为.wav的音频文件
4.在CXXXXView的构造函数中添加:
PlaySound(MAKEINTRESOURCE(IDR_TAOBAO_SENT_SOUND),AfxGetResourceHandle(),SND_ASYNC|SND_RESOURCE);
5.在该文件的上方,添加头文件#include"mmsystem.h"
6.工程->设置->连接->库模板添加"winmm.lib"
