Question

Background

My project is urgent and requires that I iterate a large XML file and return Base64 encoded images.

Each image must be inserted into an MS Word doc, and I am using the DocX library for that.

I am converting the Base64 strings to bitmap with no problem.

Problem

For the life of me, I can’t seem to get the bitmaps into a Novacode.Image object which can then be inserted to the document. NOTE: I already know how to convert to System.Drawing.Image format. It is Novacode.Image format (DocX) that is giving me grief.

If I try to convert a la (Novacode.Image)somebitmap; I get Can not cast expression of type Image to Bitmap. If I try to initialize a new Novacode.Image object I get Can not access internal constructor Image here.

Using C#, .NET 4, Forms App, lots of coffee.

Question

Only Novacode.Image objects can be inserted into the MS Word doc via the library, so how the heck do I get my bitmap in there??

I am bleary-eyed at this point so perhaps I am just missing something simple.

You have to use the DocX.AddImage() method to create a Novacode.Image object.

Follow these 5 steps to add a image to a word document:

1. Save your picture into a memory stream.
2. Create the Novacode.Image object by calling AddImage() method.
3. Create a picture by calling CreatePicture() on the Novacode.Image object created in step 2.
4. Set the shape of the picture (if needed).
5. Insert your picture into a pragraph.

The sample below shows how to insert a image into a word document:

using (DocX doc = DocX.Create(@"Example.docx"))
{
  using (MemoryStream ms = new MemoryStream())
  {
    System.Drawing.Image myImg = System.Drawing.Image.FromFile(@"test.jpg");

    myImg.Save(ms, myImg.RawFormat);  // Save your picture in a memory stream.
    ms.Seek(0, SeekOrigin.Begin);                    

    Novacode.Image img = doc.AddImage(ms); // Create image.

    Paragraph p = doc.InsertParagraph("Hello", false);

    Picture pic1 = img.CreatePicture();     // Create picture.
    pic1.SetPictureShape(BasicShapes.cube); // Set picture shape (if needed)

    p.InsertPicture(pic1, 0); // Insert picture into paragraph.

    doc.Save();
  }
}

Hope, this helps.
