Example


The following VB example demonstrates the use of a scroll control for real-time adjustment of the camera's gain.

Private Sub
 Form_Load()

ActiveGeni1.Acquire=
True

HScroll1.Value = ActiveGeni1.GainRaw
HScroll1.Min = ActiveGeni1.GetFeatureMin("GainRaw")
HScroll1.Max = ActiveGeni1.GetFeatureMax("GainRaw")
End Sub


Private Sub
 HScroll1_Scroll()

ActiveGeni1.GainRaw = HScroll1.Value

End Sub

 

Remarks


This property changes the camera's video signal amplification. The valid property range can be retrieved by the GetFeatureMin and GetFeatureMax methods.

Note that the property is available only if the currently selected camera supports the GainRaw feature per GenICam standard.
