Ah, a bit more complex as it is a callback method called from a plugin/component. I guess QPix?
Are you sure the event constants are the correct ones? : ($event=imageSaved) : ($event=resolution) : ($event=pixelFormat) I've never used this plugin, but in the online manual I found qpx_AcqImgeSaved, qpx_AcqSetupResolution as event kind param constants. You might be checking invalid events where the eventInfoParam is not the expected value.
