首先,VS2010中已经有GDI+SDK包的,不需要额外下载
1:在stdafx.h文件中加入下面3行代码,添加相应的头文件和库
#pragma comment( lib, "gdiplus.lib" )
#include "gdiplus.h"
using namespace Gdiplus;
2:定义一个全局变量 ULONG_PTR m_gdiplusToken;
其中,ULONG_PTR是一个DWORD数据类型,该成员变量用来保存GDI+被初始化后在应用程序中的GDI+标识,以便能在应用程序退出后,引用该标识来调用Gdiplus:: GdiplusShutdown来关闭GDI+。
3:使用GDI+函数前,先,最好放在OnInitDialog()中
Gdiplus::GdiplusStartupInput gdiplusStartupInput;
Gdiplus::GdiplusStartup(&m_gdiplusToken, &gdiplusStartupInput, NULL);
或者
3.在C****App的InitInstance()中加入:
//初始化GDI+
GdiplusStartupInput gsi;
GdiplusStartup(&m_gdiplusToken,&gsi,NULL);
4.重载ExitInitInstance()函数
Gdiplus::GdiplusShutdown(m_gdiplusToken);
这就是基本的配置了

在MFC里使用GDI+
(2008-03-12 11:31:20)
1. 在"stdafx.h"里加入以下:
#include <gdiplus.h>
using namespace
Gdiplus;
#pragma comment(lib, "gdiplus.lib")
2. 为CWinApp的派生类增加两个成员:
ULONG_PTR
m_gdiplusToken;
GdiplusStartupInput m_gdiplusStartupInput;
3. 在该派生类的InitInstance()函数中加入
GdiplusStartup(&m_gdiplusToken,
&m_gdiplusStartupInput, NULL);
4. 在该派生类的ExitInstance()函数中加入
GdiplusShutdown(m_gdiplusToken);
5. 到此,基本上已经可以用了,例如:
Graphics g(this->GetSafeHwnd(),TRUE);
Pen
myPen(Color::Red,50);
myPen.SetWidth(20);
g.DrawLine(&myPen,50, 50,
145, 365);
6. 但是,假如你用以下代码却不能编译通过:
Graphics
g(this->GetSafeHwnd(),TRUE);
Pen* myPen = new
Pen(Color::Red,50);
g.DrawLine(myPen,50, 50, 145, 365);
提示
error C2660:
“Gdiplus::GdiplusBase::operator new” : 函数不接受 3 个参数
的错误。
7. 要解决此问题,需参考微软的文章,全文如下:
PRB: Microsoft Foundation
Classes DEBUG_NEW Does Not Work with GDI+
Article ID : 317799
Last Review : February 12,

SYMPTOMS
When you build a
debug version of a Microsoft Foundation Classes (MFC) application that uses
GDI+, you may receive an error message that resembles the following:
error C2660: ‘Gdiplus::GdiplusBase::operator new‘ : function does
not take 3 parameters
CAUSE
In debug builds, MFC
defines a preprocessor macro that expands the new operator to an overloaded new
operator that takes two extra parameters. The extra parameters are the source
file name and code line number. MFC can use this information to report memory
leaks to the programmer when in debug mode. This works for MFC classes because
MFC provides overloads for new that accept the extra parameters.
However, because this expansion is done by the preprocessor, it
affects all usage of the new operator. If any non-MFC classes are used in the
project, their new operator is also expanded, even if no suitable overload of
new is available in that class. This is what happens in GDI+, and as a result,
you receive a compile-time error message.
WORKAROUND
To work around
this problem, choose one of the following methods:
" Turn off the preprocessor expansion by commenting
out the following lines of code in the source file:
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
NOTE: This method has the disadvantage of
not using features in MFC that help you track memory allocations and
leaks.
" Provide GDI+ with overloads for new and delete operators by
writing some code that accepts and discards the additional parameters. You can
paste the following code, which demonstrates this approach, into a new header
file and include the new header file instead of the Gdiplus.h file.
//// Ensure that GdiPlus header files work properly with
MFC DEBUG_NEW and STL header files.
#define iterator _iterator
#ifdef _DEBUG
