Alpha Fusion menu item

1. Add the Alpha Fusion menu item, modify the corresponding properties, create a Class Wizard, and edit the message processing function.

2. Add the following code to the message processing function:

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) {// select the file name

Strfilename = filedlg. m_ofn.lpstrfile;

If (filedlg. m_ofn.nfileextension = 0) {// No file suffix

Strextension = Name [filedlg. m_ofn.nfilterindex];

Strfilename = strfilename + '.' + strextension;

// Add the file suffix

}

Src1 = cvloadimage (strfilename );

If (src1)

{

MessageBox ("You also need to open an image! ");

}

Cfiledialog filedlg (true, null, null, ofn_hidereadonly, csfilter2 );

If (filedlg. domodal () = idok) {// select the file name

Strfilename = filedlg. m_ofn.lpstrfile;

If (filedlg. m_ofn.nfileextension = 0) {// No file suffix

Strextension = Name [filedlg. m_ofn.nfilterindex];

Strfilename = strfilename + '.' + strextension;

// Add the file suffix

}

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 );

}

}

}

Play wav music

1. Insert a resource (insert-> resource-> Custom-> (enter Wava ))

2. Find the "Wava" file in resources and open an idr_wava1 file.

3. Right-click and choose import from the shortcut menu to view audio files suffixed with .wav.

4. Add the following in the constructor of cxxxxview:

Playsound (makeintresource (Idr_taobao_sent_sound), Afxgetresourcehandle (), snd_async | snd_resource );

5. Add the header file # include "mmsystem. H" at the top of the file"

6. Project-> Settings-> connection-> library template Add "winmm. lib"
