TriggerDelay

Description

Returns or sets the raw value of the trigger delay.


Syntax

[VB]
objActiveDcam.TriggerDelay [= Value]

[C/C++]
HRESULT get_TriggerDelay( long *pTriggerDelay );
HRESULT put_TriggerDelay( long TriggerDelay );


Data Type [VB]

Long

Parameters [C/C++]

pTriggerDelay [out,retval]

Pointer to the current trigger delay value

TriggerDelay [in]

The trigger delay value to be set

Return Values

S_OK

Success

E_FAIL

The trigger delay control is not available for the selected camera

E_INVALIDARG

The value is out of range

Example

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

Private Sub Form_Load()
ActiveDcam1.Acquire=True
HScroll1.Value = ActiveDcam1.TriggerDelay
HScroll1.Min = ActiveDcam1.GetTriggerDelayMin
HScroll1.Max = ActiveDcam1.GetTriggerDelayMax
End Sub

Private Sub HScroll1_Scroll()
ActiveDcam1.TriggerDelay = HScroll1.Value
End Sub

Remarks

This property changes the trigger delay which defines the time between the arrival of the trigger signal and acquisition of the frame.

The valid property range is reported by the GetTriggerDelayMin and GetTriggerDelayMax methods. Note that the property is available only if the currently selected camera supports software trigger delay control.
