CHandleImage 自己写的用GDI+处理图像的一个类

 

  该类可以实现的功能：

          在图像上选定某一矩形区域并查看

          使用左右方向键调整矩形区域大小，使用向下方向键重新生成一个矩形区域

          鼠标点击某区域，可以查看此区域内的图像

          删除建立好的区域等

使用时要先初始化，主要初始化m_pImageObj、m_pGraphics1、rectTracker1

 

初始化阶段：

      1.   设置要处理的图像 

     m_handleImage.m_pImageObj=m_pImage; //m_pImageObj为Bitmap*类型  可以在OnDraw中设置

 

     2.  设置处理图像的绘图设备环境
     

    需在OnDraw中设置if (m_handleImage.headRectTraker!=NULL){if (m_handleImage.m_pGraphics1!=NULL)delete m_handleImage.m_pGraphics1;Graphics *pG=new Graphics(&bmp);m_handleImage.m_pGraphics1=pG;    //所有的绘制工作都是在位图中预先绘制pt=m_ClientRect.TopLeft();  //新建位图Bitmap bmp(m_ClientRect.Width(),m_ClientRect.Height());相对于视图的偏移量m_handleImage.DrawRectLock(pt); //位图绘制完毕后，将绘图设备重置为：视图绘图区 GetDC()->m_hDCif (m_handleImage.m_pGraphics1!=NULL)delete m_handleImage.m_pGraphics1;m_handleImage.m_pGraphics1=new Graphics(GetDC()->m_hDC);}

 

需在锁定时设置void NewImageView::OnBnClickedButton7()  //锁定图片{// TODO: 在此添加控件通知处理程序代码m_handleImage.m_bLock=!m_handleImage.m_bLock;if (m_handleImage.m_bLock){GetDlgItem(IDC_BUTTON7)->SetWindowText(_T("取消锁定"));}else{GetDlgItem(IDC_BUTTON7)->SetWindowText(_T("锁定图片"));}SetRectTracker();  Invalidate(FALSE);if(m_handleImage.m_pGraphics1!=NULL)   //  实时更新绘图设备上下文环境{delete m_handleImage.m_pGraphics1;m_handleImage.m_pGraphics1=new Graphics(GetDC()->m_hDC);}elsem_handleImage.m_pGraphics1=new Graphics(GetDC()->m_hDC);}

 

  3  以屏幕显示的图像为橡皮筋区域，设置橡CHandleImage类的皮筋区域（橡皮筋区域的坐标为视图坐标系） 
    
     在ONSIZE中 需重新设置橡皮筋区域
     在放大缩小或移动图片时，也需要重新设置橡皮筋区域

  void NewImageView::SetRectTracker()  {  CRectTracker rectTracker1;  int x,y,cx,cy; //橡皮筋的起始位置和长宽  rectTracker1.Draw(GetDC());  int nWidth = m_ImgW/m_fRate*m_fzoom;  int nHeight = m_ImgH/m_fRate*m_fzoom;  if(m_fzoom>1.0)  {  x=m_ClientRect.TopLeft().x+m_Point.x;  y=m_ClientRect.TopLeft().y+m_Point.y;  cx=m_pBmp->GetWidth();  cy=m_pBmp->GetHeight();  }  else  {  x=m_ClientRect.TopLeft().x+(m_ClientRect.Width()-nWidth)/2;  y=m_ClientRect.TopLeft().y+(m_ClientRect.Height()-nHeight)/2;  cx=m_pBmp->GetWidth();  cy=m_pBmp->GetHeight();  }  rectTracker1.m_rect.SetRect(x,y,x+cx,y+cy); //设置橡皮筋区域  m_handleImage.m_RectTracker1=rectTracker1;   m_handleImage.AdjustAllRect();  //调整矩形  m_handleImage.ReSetLinePos();   //调整线  }

 

一个简单的例子：
