C++ gdiplus成员不明确

我正试图在win32控制台应用程序（VS 2012）中运行此页面中的代码 有以下错误：

在gdiplusinit.h中，我看到GdiplusStartupInput、GdiplusStartupOutput和DebugEventLevel是模棱两可的。有人知道如何解决这个问题吗？

链接器无法解决您发布的所有错误。

似乎您忘记将库（类似于

gdi.lib

或

gdiplus.lib

）添加到VS项目中。

这里没有歧义，您只是忘记链接gdiplus.lib。将其添加到链接器的输入+附加依赖项设置中

一种简单的方法是将link指令放入源代码中：

#include <windows.h>
#include <gdiplus.h>
#pragma comment(lib,"gdiplus.lib")

#包括
#包括
#pragma注释（lib，“gdiplus.lib”）

有关在使用Visual Studio时添加提到的gdiplus.lib的其他信息。在解决方案资源管理器中右键单击项目。选择属性。折叠打开连接器部分。选择输入。将gdiplus.lib添加到Additional Dependencies的值中。是的，这是它在第一段中所说的。我知道，但我花了一些时间试图找出位置。因此，我的评论只是在你的回答之上做了一些额外的澄清
