How can i read the CVB Color Format(defined in the GenICam Device Configurator) programatically via the C++ API?

I have found a function to set it, but no function to get/read it.

Hi @popeye

the CVB Color Format form the GenICam device configuration is written into the GenICam.ini file as integer. This file is located in %CVBDATA%/drivers. The format will be applied to the streamed images if you load a device using the GenICam.vin.  
There is no direct way to read it, except from the INI file.  
Can you describe your use case, I guess there is another way to cover your requirement.

If you use the discover interface (`DeviceFactory::Discover`), you can call `.SetParameter("PixelFormat", "0")` on the returned entries (not on the list). The `"0"` is the value from the _ini_ file; meaning raw in this case.
