Halcon

Programming with HALCON

HALCON offers various language interfaces, such as a C++ and a native .NET interface. Using these interfaces you can access all of HALCON's more than 1800 powerful operators from programming languages like C, C++, C#, Visual Basic, or Delphi.

HALCON's open architecture allows you to access defined data structures and thus to integrate it with further software components such as a user interface or process control. HALCON's inbuilt high-performance memory management lets you concentrate on your application development.

  • HALCON/.NET:     In HALCON/.NET all HALCON operators and data structures are available as high-level classes, greatly simplifying the development of your application. HALCON/.NET can be used in .NET languages like C#, Visual Basic .NET, and C++. It can be used on Windows and with Mono also on Linux.
    private void timerCycle_Tick(object sender, System.EventArgs e)
    {
        HTuple results;
    
        // Create instance of reader without special parameters
        HBarCode reader = new HBarCode(new HTuple(), new HTuple());
    
        // Acquire next image
        HImage image = acquisition.GrabImage();
    
        // Find and decode bar codes of type EAN 13
        HRegion regions = reader.FindBarCode(image, "EAN-13", out results);
    
        if (results.Length > 0)
        {
            // Display image and bar code regions in graphics window
            window.DispImage(image);
            window.DispRegion(regions);
    
            // Display decoded result of first found bar code in a text box
            textBoxCode.Text = results[0];
        }
        else
        {
            textBoxCode.Text = "Not found!";
        }
    
        // Cleanup (could also be done using the garbage collector)
        regions.Dispose();
        image.Dispose();
        reader.Dispose();
    }
    With only a few lines of C# code you can build the entire application, e.g., to decode bar codes.
  • HALCON/C++:     With HALCON/C++ you can access the whole functionality of HALCON based on a C++ class hierarchy. This enables you to develop programs that are very compact and easy to maintain. HALCON/C++ is available on Windows, Linux and Mac OS X.
  • HDevelop:     If you develop your solution with the interactive rapid prototyping environment HDevelop the integration is very easy, since HDevelop can export your application as C++, C, C#, or Visual Basic source code.
  • HDevEngine:     HDevEngine - the "HDevelop Engine" - is a library that acts as an interpreter and lets you directly load and execute HDevelop programs and procedures from within your C++, C#, or Visual Basic application.
  • Parallel Programming:     HALCON not only supports multithreading and parallel programming, but also provides automatic parallelization to exploit the power of multi-core or multiprocessor hardware. Read more about multi-core performance.
  • HALCON Codelets:     Source code modules and classes – HALCON codelets – are used outside the development environment HDevelop. Many of these modules as well as corresponding example applications are available as source code and can be used as templates for new applications or directly called within newly developed code.
  • Protection of Know-how:     HALCON secures the know-how of the software developer: code, which is saved in external or local procedures, as well as code of entire procedure libraries or programs can be secured with a password. Therefore, functionality can be shared without revealing the program code.
