  1. Region of InterestPart II Ku-Yaw Chang canseco@mail.dyu.edu.tw Assistant Professor, Department of Computer Science and Information Engineering Da-Yeh University

  2. Outline • Get DC • Drawing Mode - XOR • Complete ROI Medical Imaging System

  3. Get DC • Provided by the framework • void C***View::OnDraw(CDC* pDC) • To obtain DC elsewhere CDC * pDC = GetDC(); : // use pDC … : ReleaseDC(pDC); Medical Imaging System

  4. Drawing Mode - XOR ( A  B ) B = A Medical Imaging System

  5. Drawing Mode - XOR • Specifies the new drawing mode. • pDC->SetROP2(R2_XORPEN); Medical Imaging System

  6. Complete ROI • Add a state variable m_bLBtnDown into C***View • To keep track of the status of the mouse’s left button • Initialization : set to be ‘false’ • OnLButtonDown : set to be ‘true’ • OnLButtonUp : set to be ‘false’ Medical Imaging System

  7. Complete ROI • Use two variables to record the first and second points (C***View) • m_ptFirst and m_ptSecond • OnLButtonDown • m_ptFirst = point; • m_ptSecond = point; • OnLButtonUp • m_ptSecond = point; Medical Imaging System

  8. Complete ROI • OnMouseMove • Check m_bLBtnDown • Erase previous (old) ROI • m_ptFirst and m_ptSecond • m_ptSecond = point; • Draw new ROI • m_ptFirst and m_ptSecond Medical Imaging System

  9. Other Considerations • Scrollbar • CPoint GetScrollPosition() • Display ratio • m_nDisplayRatio Medical Imaging System
