I know this is most likely not what you want, since it is not free.
But Aspose can do what you need.
Spire.doc too. Again, not free.
Aspose:
string exeDir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + Path.DirectorySeparatorChar;
string dataDir = new Uri(new Uri(exeDir), @"../../Data/").LocalPath;
// Open the document.
Document doc = new Document(dataDir + "SaveAsPNG.doc");
//Create an ImageSaveOptions object to pass to the Save method
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.Png);
options.Resolution = 160;
// Save each page of the document as Png.
for (int i = 0; i < doc.PageCount; i++)
{
options.PageIndex = i;
doc.Save(string.Format(dataDir+i+"SaveAsPNG out.Png", i), options);
}
Spire.doc (WPF):
using Spire.Doc;
using Spire.Doc.Documents;
namespace Word2Image
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
Document doc = new Document("sample.docx", FileFormat.Docx2010);
BitmapSource[] bss = doc.SaveToImages(ImageType.Bitmap);
for (int i = 0; i < bss.Length; i++)
{
SourceToBitmap(bss[i]).Save(string.Format("img-{0}.png", i));
}
}
private Bitmap SourceToBitmap(BitmapSource source)
{
Bitmap bmp;
using (MemoryStream ms = new MemoryStream())
{
PngBitmapEncoder encoder = new PngBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(source));
encoder.Save(ms);
bmp = new Bitmap(ms);
}
return bmp;
}
}
}
