Example


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

Private Sub
 Form_Load()

HScroll1.Value = ActiveGeni1.GainAbs
HScroll1.Min = ActiveGeni1.GetFeatureMin ("GainAbs")
HScroll1.Max = ActiveGeni1.GetFeatureMax ("GainAbs")
ActiveGeni1.Acquire=
True

End Sub


Private Sub
 HScroll1_Scroll()

ActiveGeni1.GainAbs = HScroll1.Value

End Sub

 

Remarks


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

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