推荐答案

尝试完成的只是简单地编写具有透明背景的文字;即您正在尝试获取一些形式的alpha混合文本写在图像上。

最简单的方法是使用GDI +例程。它们被封装用于delphi，可从 http://www.progdigy.com/ 下载。有很多例子应该可以用作一个例子。

I presume what you're trying to accomplish is a little more complicated than simply writing text with a transparent background; i.e. you are trying to get some form of alpha-blended text written on the image.
The simplest method would be to make use of the GDI+ routines. They are encapsulated for delphi and available for download from http://www.progdigy.com/. There are many examples there which should be usable as an example.
