cv::Mat faceMat(mydata.depthPic,mydata.faceRec);
  

  cv::Mat faceMat_resize(this->pb_right->Height,this->pb_right->Width,faceMat.type());
  

  cv::resize(faceMat,faceMat_resize, faceMat_resize.size(),0.0,0.0,cv::INTER_LINEAR);
  

  cv::imshow("origin",faceMat);
  

  cv::imshow("painted",faceMat_resize);
  

  img=ConvertMatToBitmap(faceMat_resize);
  

  this->pb_right->Image=img;
  

  

  其中 cv::imshow能正常显示图片，但是pb_right显示不出图片。
  

  而img=ConvertMatToBitmap(faceMat);确可以正常显示图片。
  

  求问:
  

  System::Drawing::Bitmap^ bmpImg;   那个^代表什么意思？这样的变量是个指针还是有具体分配的空间？
  

  怎么样让pb_right可以正确显示faceMat_resize的内容?
  

  

  下面是ConvertMatToBitmap的函数体:
  

  System::Drawing::Bitmap^ FaceAnalyze::ConvertMatToBitmap(cv::Mat& cvImg)
  

  {
  

  System::Drawing::Bitmap^ bmpImg;
  

  //检查图像位深
  

  if(cvImg.depth() != CV_8U)
  

  {
  

  bmpImg = gcnew System::Drawing::Bitmap(1,1,System::Drawing::Imaging::PixelFormat::Format8bppIndexed);
  

  return (bmpImg);
  

  }
  

  //彩色图像
  

  if(cvImg.channels() == 3)
  

  {
  

  bmpImg = gcnew System::Drawing::Bitmap(
  

  cvImg.cols,
  

  cvImg.rows,
  

  cvImg.step,
  

  System::Drawing::Imaging::PixelFormat::Format24bppRgb,
  

  (System::IntPtr)cvImg.data );
  

  }
  

  else if(cvImg.channels() == 4)
  

  {
  

  bmpImg = gcnew System::Drawing::Bitmap(
  

  cvImg.cols,
  

  cvImg.rows,
  

  cvImg.step,
  

  System::Drawing::Imaging::PixelFormat::Format32bppArgb,
  

  (System::IntPtr)cvImg.data );
  

  }
  

  //灰度图像
  

  else if(cvImg.channels() == 1)
  

  {
  

  bmpImg = gcnew System::Drawing::Bitmap(
  

  cvImg.cols,
  

  cvImg.rows,
  

  cvImg.step,
  

  System::Drawing::Imaging::PixelFormat::Format8bppIndexed,
  

  (System::IntPtr)cvImg.data);
  

  }
  

  return (bmpImg);
  

  }
