cximage开源软件应用

搞个 cximage702_full导入VS2010编译后

1.把所有.lib文件和.dll文件拷贝到 新项目的CXIMAGE文件夹里

2.在新项目的stdfx.h或所需要的文件里输入以下引用

#include "CXIMAGE/ximage.h"   
//#pragma comment(lib, "CXIMAGE/cximaged.lib")
//#pragma comment(lib, "CXIMAGE/cximagecrtd.lib")//在静态链接库中使用
#pragma comment(lib, "CXIMAGE/cximage.lib")
#pragma comment(lib, "CXIMAGE/png.lib")
#pragma comment(lib, "CXIMAGE/jpeg.lib")
#pragma comment(lib, "CXIMAGE/zlib.lib")
#pragma comment(lib, "CXIMAGE/tiff.lib")
#pragma comment(lib, "CXIMAGE/jbig.lib")
#pragma comment(lib, "CXIMAGE/jasper.lib")
#pragma comment(lib, "CXIMAGE/mng.lib")
#pragma comment(lib, "CXIMAGE/libdcr.lib")
#pragma comment(lib, "CXIMAGE/libpsd.lib")

3.如果用静态链接库编译或者生成带界面的MFCDLL 运行模式需要"release",

在引用时将MFCDLL生成的DLL和CXIMAGE/cximagecrtd.dll,CXIMAGE/cximaged.dll拷贝到目标工程目录中，

typedef void (*lpFun)(void);         
HINSTANCE hDll;   //DLL句柄  
lpFun pShowDlg; 
hDll = LoadLibrary(L"RegularDLL.dll");
if (NULL==hDll)
{
return ;
} 
pShowDlg = (lpFun)GetProcAddress(hDll,"ShowDlg");
if (NULL==pShowDlg)
{
return ;
}
pShowDlg(); 
FreeLibrary(hDll);

4.测试代码

CxImage image;  
CRect m_rect;
HBITMAP m_bitmap;
#define xishu 0.8

void CkkkDlg::OnBnClickedOk()
{
GetWindowRect(&m_rect);//GetWindowRect(&m_rect); //获得控件客户窗口大小 
image.Load(L"test00111.jpeg", CXIMAGE_FORMAT_JPG); 
if (image.IsValid()) 
{ 
//if (m_bitmap) DeleteObject(m_bitmap); 
image.Resample(m_rect.Width()*xishu, m_rect.Height()*xishu); //按照Picture控件的大小，（不按比例）缩放原始图片 
m_bitmap = image.MakeBitmap(m_picture.GetDC()->m_hDC); 
m_picture.SetBitmap(m_bitmap); 
//HBITMAP OldBitmap = m_picture.SetBitmap(m_bitmap); 
//if (OldBitmap) DeleteObject(OldBitmap);  
} 
}

void CkkkDlg::OnBnClickedButton2()//jpeg图片拼接
{
CxImage t_img1,t_img2,t_img3;


int t_h1,t_w1,t_h2,t_w2,t_h3,t_w3,t_bpp;


t_img1.Load(L"test00222.jpeg");

t_w2=t_img2.GetWidth();


t_h3=t_h1;


t_w3=t_w1+t_w2;


t_bpp=t_img1.GetBpp();


t_img3.Create(t_w3,t_h3,t_bpp);


t_img3.MixFrom(t_img1,0,0);


t_img3.MixFrom(t_img2,t_w1,0);


t_img3.Save(L"3.jpeg",CXIMAGE_FORMAT_JPG);
}


void  CkkkDlg::zoom(float zoom)
{
int left = m_rect.Width()*xishu*zoom-m_rect.Width()*xishu;
