Image Acquisition: Saving a sequence of single images

The following programming example (Visual Basic) shows how you can use IC Imaging Control to grab an image from a device's live image data stream and to write it to a BMP file whose name is created automatically. Thus, you can generate a sequence of single images in a very simple way.

The sample application's window looks as follows:

The program starts by activating a built-in dialog to select a device (.ShowDeviceSettingsDialog). Then the device's live image data stream is displayed using .LiveStart (see image on the right):

Private Sub Form_Load()

    ImageNumber = 0

    ICImagingControl1.ShowDeviceSettingsDialog

    If ICImagingControl1.DeviceValid Then
        ICImagingControl1.LiveStart
    Else
        Unload Me
    End If

End Sub

When the user clicks "Save Next Image", .MemorySnapImage grabs an image from the image data stream and writes it into an internal ring buffer. Then, .MemorySaveImage forwards it to a BMP file:

Private Sub btnSaveNextImage_Click()

    ICImagingControl1.MemorySnapImage

    Dim filename As String
    filename = "Image " & ImageNumber & ".bmp"

    ICImagingControl1.MemorySaveImage filename

    ImageNumber = ImageNumber + 1

End Sub
