Tutorial

    Step 1: Call EM_Init to initialize CPMLIP as following example.

┅
LPTSTR lpBuffer = (LPTSTR)(new char[256]);
GetCurrentDirectory(256,lpBuffer);
EM_Init(lpBuffer);
delete []lpBuffer;
┅

    Step 2: Set parent window. For showing directly,you must set the SDL window in your application program's view window. This you should call EM_SetParentWnd as following codes.More see the sample of "demovc".

BOOL CDemovcApp::InitInstance()
{
    ┅
    char* pPopTitle = "Demovc(Cross Platform Multiple Layer Image Process SDK)";
    m_pMainWnd->SetWindowText(pPopTitle);
    m_pMainWnd->ShowWindow(SW_SHOW);
    m_pMainWnd->UpdateWindow();

    LPTSTR lpBuffer = (LPTSTR)(new char[256]);
    GetCurrentDirectory(256,lpBuffer);
    EM_Init(lpBuffer);
    delete []lpBuffer;

    CString str;
    g_pMyView1->GetWindowText(str);
    char* pParentTitle = str.GetBuffer(str.GetLength());
    EM_SetParentWnd(pPopTitle,pParentTitle);
    ┅
    return TRUE;
}

    Step 3: Call EM_SetPeekMessageFunction to set a function which can peek mouse messages and keyboard events.

    Step 4: To process texts you should call EM_GetTTFFaceName to create a font table which contains file names of all system fonts and all font's face names. Maybe you will show them in your font dialog, but prior thing is that it will create a same table in "fontlayer.dll", so that CPMLIP can create different images with different fonts. Give a exameple:

//---------------------------------------------------------------------------
//Create font table

#define MAX_FONT_COUNT     512
#define MAX_FACENAME       100
static  EM_FontTable       g_fonttable[MAX_FONT_COUNT];
static  int                g_fontcount = 0;

void CreateFontTable(){
#ifdef WIN32 // for windows

    LPITEMIDLIST pidl;
    LPMALLOC     pShellMalloc;
    char         szDir[MAX_PATH];
    char         filespec[MAX_PATH];
    long         hFile;
    _finddata_t  fileinfo;
    if(SUCCEEDED(SHGetMalloc(&pShellMalloc))){
        if(SUCCEEDED(SHGetSpecialFolderLocation(NULL, CSIDL_FONTS, &pidl))){    
            if(SHGetPathFromIDList(pidl, szDir)) {
                int len = strlen(szDir);
                if (szDir[len-1] != '\\')
                strcat(szDir,"\\");
            }
            pShellMalloc->Free(pidl);
        }
        pShellMalloc->Release();
    }
    strcpy(filespec, szDir);
    strcat(filespec, "*.ttf");
    if ((hFile = _findfirst(filespec, &fileinfo)) != -1){
        do{
            if (!(fileinfo.attrib & _A_SUBDIR)){
                char filename[MAX_PATH];
                strcpy(filename, szDir);
                strcat(filename, fileinfo.name);
                char pfacename[MAX_FACENAME];
                EM_GetTTFFaceName(filename, pfacename);
                int exist = 0;
                for(int i = 0; i < g_fontcount; i ++){
                    if(strcmp(pfacename , g_fonttable[i].name) == 0)
                        exist = 1;
                }
                if(exist == 0){
                    strcpy(g_fonttable[g_fontcount].path, filename);
                    strcpy(g_fonttable[g_fontcount].name, pfacename);
                    g_fontcount++;
                }
            }
        } while (_findnext(hFile, &fileinfo) == 0);
    _findclose(hFile);
    }
#else

#endif
