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.GainAbs
HScroll1.Min = ActiveGige1.GetFeatureMin ("GainAbs")
HScroll1.Max = ActiveGige1.GetFeatureMax ("GainAbs")
ActiveGige1.Acquire=True
End Sub

Private Sub HScroll1_Scroll()
ActiveGige1.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.
