Dodaj obraz do struktury OpenXml

private string AddGraph(WordprocessingDocument wpd, string filepath)
{
    ImagePart ip = wpd.MainDocumentPart.AddImagePart(ImagePartType.Jpeg);
    using (FileStream fs = new FileStream(filepath, FileMode.Open))
    {
        if (fs.Length == 0) return string.Empty;
        ip.FeedData(fs);
    }

    return wpd.MainDocumentPart.GetIdOfPart(ip);
}

W tym przypadku używamy FileStream do pobierania obrazu, ale feedData (Stream) czeka na dowolny strumień.

W tym przykładzie ustawiłem rozmiar statyczny na 800 * 600, ale możesz ustawić dowolny potrzebny rozmiar
