Image Acquisition: Saving an image (BMP)

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 write it to a BMP file.

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()

    ICImagingControl1.ShowDeviceSettingsDialog

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

End Sub

When the user clicks "Save BMP", .MemorySnapImage grabs an image from the image data stream and writes it into an internal ring buffer. Then .ShowSave activates the Windows dialog to save a file. In the last step .MemorySaveImage writes the buffered image to this file:

Private Sub btnSaveBMP_Click()

    ICImagingControl1.MemorySnapImage

    CommonDialog1.DefaultExt = "bmp"
    CommonDialog1.Filter = "BMP Images (*.bmp)|*.bmp|"
    CommonDialog1.ShowSave

    If CommonDialog1.FileName <> "" Then

        ICImagingControl1.MemorySaveImage CommonDialog1.FileName

    End If

End Sub
