推荐答案

我使用此代码：

I use this code:

    CDC sdc;
sdc.CreateDC(_T("DISPLAY"), NULL, NULL, NULL);
CDC dc;
dc.CreateCompatibleDC(&sdc);
CBitmap bmp;
//bmp.LoadOEMBitmap(IDB_BGBitmap);
bmp.CreateCompatibleBitmap(&sdc, 672, 480);
auto old_bmp = dc.SelectObject(bmp);
dc.FillSolidRect(0,0, 672, 480, RGB(255, 255, 255));
dc.SetBkMode(TRANSPARENT);
dc.SetBkColor(RGB(255,255,255));

dc.TextOut(10, 10, CString("Test"));
dc.SelectObject(old_bmp);

CBitmap bmp2;
bmp2.Attach(bmp.Detach());


CPictureHolder pictholder;    //our temp 'converter'
pictholder.CreateFromBitmap(bmp2);    //put the image variable into a container

imResult.putref_Picture(pictholder.GetPictureDispatch());
RedrawWindow();

所以我可以在图片上绘制文字;

so I can draw text on picture ;
