The sample demonstrates how to save a Word document to image with Spire.Doc.

private void button1_Click(object sender, EventArgs e)
{
    //Create word document
    Document document = new Document();
    document.LoadFromFile(@"..\..\..\..\..\..\Data\FindAndReplace.doc");

    //Save doc file.
    Image img = document.SaveToImages(0, ImageType.Bitmap);
    img.Save("sample.bmp");

    //Launching the image file.
    WordDocViewer("sample.bmp");
}

private void WordDocViewer(string fileName)
{
    try
    {
        System.Diagnostics.Process.Start(fileName);
    }
    catch { }
}

Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click
	'Create word document
	Dim document_Renamed As New Document()
	document_Renamed.LoadFromFile("..\..\..\..\..\..\Data\FindAndReplace.doc")

	'Save doc file.
	Dim img As Image = document_Renamed.SaveToImages(0, ImageType.Bitmap)
	img.Save("sample.bmp")

	'Launching the image file.
	WordDocViewer("sample.bmp")
End Sub

Private Sub WordDocViewer(ByVal fileName As String)
	Try
		Process.Start(fileName)
	Catch
	End Try
End Sub
