void CHelloWorldPlusAppView::SaveL()
{
    TRect rect = Rect();
    CFbsBitmap* iBitmap=new(ELeave)CFbsBitmap();
    //Create a bitmap from specified rect
    iBitmap->Create(rect.Size(),EColor256);
    CCoeEnv::Static()->ScreenDevice()->CopyScreenToBitmap(iBitmap,rect);

Hi all ! I can do that . And this my way !

void CHelloWorldPlusAppView::SaveL()
{
    //Make a snapshot
    TRect rect = Rect();
    iFileSaver->CreateL      (KBmpFileName,&iClipFormat,&iCodec,&iCodec);
    iBitmap=new(ELeave)CFbsBitmap();
    //Create a bitmap from specified rect
    iBitmap->Create(rect.Size(),EColor256); // Adapt with your display mode
    CCoeEnv::Static()->ScreenDevice()->CopyScreenToBitmap(iBitmap,rect);
}



//This function is called when the gif file has been opened or an error has occured in the process
void CHelloWorldPlusAppView::MiuoOpenComplete(TInt aError)
{
}

//This function is called whenever a conversion process has finished
void CHelloWorldPlusAppView::MiuoConvertComplete(TInt aError)
{
}

//This function is called when the bitmap (output) file has been created
void CHelloWorldPlusAppView::MiuoCreateComplete(TInt aError)
{
    iFileSaver->ConvertL(*iBitmap);
}
