## Examples

Shows how to add new image with tag.

```csharp
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_Tags();

// Create an object of the Document class
Document doc = new Document();

// Initialize Page class object
Aspose.Note.Page page = new Aspose.Note.Page(doc);

// Initialize Outline class object
Outline outline = new Outline(doc);

// Initialize OutlineElement class object
OutlineElement outlineElem = new OutlineElement(doc);

// Load an image
Aspose.Note.Image image = new Aspose.Note.Image(doc, dataDir + "icon.jpg");

// Insert image in the document node
outlineElem.AppendChildLast(image);
image.Tags.Add(NoteTag.CreateYellowStar());

// Add outline element node
outline.AppendChildLast(outlineElem);

// Add outline node
page.AppendChildLast(outline);

// Add page node
doc.AppendChildLast(page);

// Save OneNote document
dataDir = dataDir + "AddImageNodeWithTag_out.one";
doc.Save(dataDir);
```

Shows how to retrieve information about list's formatting.

```csharp
string dataDir = RunExamples.GetDataDir_Text();

// Load the document into Aspose.Note.
Document oneFile = new Document(dataDir + "ApplyNumberingOnText.one");

// Retrieve a collection nodes of the outline element
IList<OutlineElement> nodes = oneFile.GetChildNodes<OutlineElement>();

// Iterate through each node
foreach (OutlineElement node in nodes)
{
    if (node.NumberList != null)
    {
        NumberList list = node.NumberList;

        // Retrieve font name
        Console.WriteLine("Font Name: " + list.Font);

        // Retrieve font length
        Console.WriteLine("Font Length: " + list.Font.Length);

        // Retrieve font size
        Console.WriteLine("Font Size: " + list.FontSize);

        // Retrieve font color
        Console.WriteLine("Font Color: " + list.FontColor);

        // Retrieve format
        Console.WriteLine("Font format: " + list.Format);

        // Check bold
        Console.WriteLine("Is bold: " + list.IsBold);

        // Check italic
        Console.WriteLine("Is italic: " + list.IsItalic);
        Console.WriteLine();
    }
}
