halconconcat_obj两个区域组合成区域集

在HDevelop中

gen_region_line (RegionLines, 100, 50, 100, 150)
gen_region_line (RegionLines1, 150, 50, 150, 150)

concat_obj (RegionLines, RegionLines1, ObjectsConcat)
*两个区域组合成区域集
*参数3：输出区域

dev_open_window(0,100,300,300,'black',WindowHandle)
dev_display(ObjectsConcat)

在Qt Creator中

  HObject  ho_RegionLines, ho_RegionLines1, ho_ObjectsConcat;
  HTuple  hv_WindowHandle;

  GenRegionLine(&ho_RegionLines, 100, 50, 100, 150);
  GenRegionLine(&ho_RegionLines1, 150, 50, 150, 150);

  ConcatObj(ho_RegionLines, ho_RegionLines1, &ho_ObjectsConcat);
  //两个区域组合成区域集
  //参数3：输出区域

  SetWindowAttr("background_color","black");
  OpenWindow(0,100,300,300,0,"visible","",&hv_WindowHandle);
  HDevWindowStack::Push(hv_WindowHandle);
  if (HDevWindowStack::IsOpen())
    DispObj(ho_ObjectsConcat, HDevWindowStack::GetActive());
