halconget_region_points获得区域所有像素点的坐标

在HDevelop中

dev_open_window (0, 0, 300, 300, 'black', WindowHandle)
gen_region_line (RegionLines, 100, 50, 120, 50)
get_region_points (RegionLines, Rows, Columns)
*获得区域所有像素点的坐标

dev_display(RegionLines)

在Qt Creator中

  HObject  ho_RegionLines;
  HTuple  hv_WindowHandle, hv_Rows, hv_Columns;

  SetWindowAttr("background_color","black");
  OpenWindow(0,0,300,300,0,"visible","",&hv_WindowHandle);
  HDevWindowStack::Push(hv_WindowHandle);
  GenRegionLine(&ho_RegionLines, 100, 50, 120, 50);
  GetRegionPoints(ho_RegionLines, &hv_Rows, &hv_Columns);
  //获得区域所有像素点的坐标

  if (HDevWindowStack::IsOpen())
    DispObj(ho_RegionLines, HDevWindowStack::GetActive());
