Cannot find references for awb_gains #82

Open kauevestena opened 5 years ago

kauevestena commented 5 years ago

Hello, i'm plannig to use the raspicam in an application where I have to use a custom White Balance, accordingly to the api reference we can change it with with awb_gains

but when I try to read the values (setting awb_mode to "off" does not change that), it says:

 ERROR: Parameter [/raspicam_node/awb_gains] is not set

And searching here in the repo, I cannot find any reference to it...

So, there is a way to use this setting? (i'm trying but it seems very buggy)

In fact, the driver just does not handle awb_gains, this is very sad for my purposes...

Where can I start, to modify the code in order to implement this functionality?
