18 Use cases
18.1 GenICam to mvIMPACT Acquire code generator
18.1.1 Using the code generator
As any GenICam™ compliant device for which there is a GenICam™ GenTL compliant capture
driver in mvIMPACT Acquire can be used using the mvIMPACT Acquire interface and it can't be
known which features are supported by a device until a device has been initialised and its
GenICam™ XML file has been processed it is not possible to provide a complete C++ wrapper for
every device statically.
Therefore an interface code generator has been embedded into each driver capable of handling
arbitrary devices. This code generator can be used to create a convenient C++ interface file that
allows access to every feature offered by a device.
Warning:
A code generated interface can result in incompatibility issues, because the interface name
will be constructed from the version and product information that comes with the GenICam
XML file (see comment in code sample below). To avoid incompatibility, please use the
common interface from the namespace mvIMPACT::acquire::GenICam whenever possible.
To access features needed to generate a C++ wrapper interface a device needs to be initialized.
Code can only be generated for the interface layout selected when the device was opened. If
interfaces shall be created for more than a single interface layout the steps that will explain the
creation of the wrapper files must be repeated for each interface layout.
Once the device has been opened the code generator can be accessed by navigating to "System
Settings -> CodeGeneration".
