编译：打开根目录下的CxImgLib.dsw工程文件，默认的编译是采用unicode-release方式编译的。为了在一般的vc6.0工程中使用，请改用debug/release版本，不包含unicode前缀。batch build编译成功后会生成一些lib文件、dll文件和demo.exe。
新建MFC测试工程，在lib文件夹中包含CxImgLib的头文件、lib文件
在工程目录下添加dll文件：cximage.dll cximagecrtd.dll
修改stdafx.h文件，
// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
//
#if !defined(AFX_STDAFX_H__0816B0BC_058B_410B_AB0D_3DB7188938DE__INCLUDED_)
#define AFX_STDAFX_H__0816B0BC_058B_410B_AB0D_3DB7188938DE__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers
#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions
#include <afxdisp.h> // MFC Automation classes
#include <afxdtctl.h> // MFC support for Internet Explorer 4 Common Controls
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h> // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT
//添加CxImage到你的程序中(目录为你上面添加位置,我把它们放在了lib文件夹中了)
#include "lib/ximage.h"
#pragma comment(lib,"lib/cximagecrtd.lib") //静态链接库时使用
#pragma comment(lib,"lib/cximage.lib")
#pragma comment(lib,"lib/Jpeg.lib")
#pragma comment(lib,"lib/consoleu.lib")
#pragma comment(lib,"lib/png.lib")
#pragma comment(lib,"lib/zlib.lib")
#pragma comment(lib,"lib/tiff.lib")
#pragma comment(lib,"lib/jasper.lib")
//#pragma comment(lib,"lib/j2k.lib")
#pragma comment(lib,"lib/jbig.lib")
#pragma comment(lib,"lib/libdcr.lib")
//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.
#endif // !defined(AFX_STDAFX_H__0816B0BC_058B_410B_AB0D_3DB7188938DE__INCLUDED_)
为测试的MFC工程添加一个按钮事件，添加代码
void CCxImageTestDlg::OnBtnSave()
{
// TODO: Add your control notification handler code here
//创建对象
CxImage *newImage = new CxImage();
newImage->Load("test.png",CXIMAGE_FORMAT_PNG);
//存储为文件,我发现的可以使用的有6个格式有三个格式未使用成功(gif,wbmg,wmf)....够用了吧?
newImage->Save("image.bmp",CXIMAGE_FORMAT_BMP); //注意不是CXIMAGE_SUPPORT_BMP
newImage->Save("image.tga",CXIMAGE_FORMAT_TGA);
newImage->Save("image.pcx",CXIMAGE_FORMAT_PCX);
newImage->Save("image.jpg",CXIMAGE_FORMAT_JPG);
newImage->Save("image.png",CXIMAGE_FORMAT_PNG);
newImage->Save("image.tiff",CXIMAGE_FORMAT_TIF);
newImage->Save("image.gif",CXIMAGE_FORMAT_GIF); //不成功,只能读取第一贞图片?
newImage->Save("image.wbmp",CXIMAGE_FORMAT_WBMP); //不成功
newImage->Save("image.wmf",CXIMAGE_FORMAT_WMF); //不成功
newImage->Save("image.mng",CXIMAGE_FORMAT_MNG); //默认-未打开此项功能
//newImage->Save("image.jbig",CXIMAGE_FORMAT_JBG); //默认-未打开此项功能
/*
* CxImage配置文件ximacfg.h
* #define CXIMAGE_SUPPORT_BMP 1 //可用状态(即不可取得和转换成这种格式)
* #define CXIMAGE_SUPPORT_MNG 0 //不可用状态
*/
}
修改编译选项：在project->setting->link->input->ignore lib中添上msvcrt.lib，避免与之冲突
编译后即可将test.png转成各种各样的image+后缀格式的文件
