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)
// 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
// Display decoded result of first found bar code in a text box
textBoxCode.Text = results;
textBoxCode.Text = "Not found!";
// Cleanup (could also be done using the garbage collector)
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
- 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.

- 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
