|
|
* Description: Interface for executing HDevelop programs and procedures
|
|
* within a C++ application using the HALCON/C++ interface.
|
|
* Attention: This engine uses the new HALCON/C++ interface that was
|
|
* introduced in HALCON 11.
|
|
* If your HDevEngine application was developed with a prior
|
|
* version of HALCON and uses the old HALCON/C++ interface
|
|
* We recommend to migrate it to the new HALCON/C++ interface.
|
|
* However, if this is not possible, you can use the legacy
|
|
* HDevEngine from the path
|
|
* %HALCONROOT%/include/hdevengine10
|
|
* In addition, your application must be linked against the
|
|
* libraries halconcpp10 and hdevenginecpp10 (instead of
|
|
* halconcpp and hdevenginecpp).
|
|
* Changes within the source files are not needed.
