推荐答案

我想建议你从下面引用的CodeProject文章中找到它，但不知道你在问关于Windows。仍然不是100％肯定，但我看到你提到MFC，你的一些其他问题是针对Windows的。请参阅：

绘制线条，形状，或位图上的文字 [ ^ ]。



请查看我对您的问题的评论，下次请理解平台标签几乎总是重要的对于你的问题。

I wanted to advise you to find it out from the CodeProject article referenced below, but wasn''t sure you are asking about Windows. Still not 100% sure, but I saw that you mentioned MFC and some of your other questions was for Windows. Please see:
Drawing lines, shapes, or text on bitmaps[^].

Please see my comments to your question, and, next time, please understand that the platform tag is almost always important for your question.

亲爱的sergey

如果你使用visual c ++，下面的代码可以帮助你：

hi dear sergey
if you work with visual c++, below code helps you:

CImage i;
i.Load(_T("a.bmp"));
CDC cdc;
cdc.Attach(i.GetDC());
cdc.TextOut(_T("Hello world"),10,10);
cdc.Detach();
i.ReleaseDC();
