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 = ActiveGige1.Gain
HScroll1.Min = ActiveGige1.GetGain
HScroll1.Max = ActiveGige1.GetGain
ActiveGige1.Acquire=True
End Sub

Private Sub HScroll1_Scroll()
ActiveGige1.Gain = 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 GetGainMin and GetGainMax methods.

Note that the property is available only if the currently selected camera supports one of the following GenICam features: Gain, GainAbs, GainRaw.
