Examples
Shows how to check if a page is a conflict page(i.e. it has changes that OneNote couldn’t automatically merge).
string dataDir = RunExamples.GetDataDir_Pages();
// Load OneNote document
Document doc = new Document(dataDir + "Aspose.one", new LoadOptions { LoadHistory = true });
var history = doc.GetPageHistory(doc.FirstChild);
for (int i = 0; i < history.Count; i++)
{
var historyPage = history[i];
Console.Write(" {0}. Author: {1}, {2:dd.MM.yyyy hh.mm.ss}",
i,
historyPage.PageContentRevisionSummary.AuthorMostRecent,
historyPage.PageContentRevisionSummary.LastModifiedTime);
Console.WriteLine(historyPage.IsConflictPage ? ", IsConflict: true" : string.Empty);
// By default conflict pages are just skipped on saving.
// If mark it as non-conflict then it will be saved as usual one in the history.
if (historyPage.IsConflictPage)
historyPage.IsConflictPage = false;
}
doc.Save(dataDir + "ConflictPageManipulation_out.one", SaveFormat.One);IsComposite
Checks whether the node is composite. If true then the node can have child nodes.
public override sealed bool IsComposite { get; }Property Value
LastChild
Gets the last child node of this node.
public T LastChild { get; }Property Value
T

Examples
Shows how to get an image from a document.
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_Images();
// Load the document into Aspose.Note.
Document oneFile = new Document(dataDir + "Aspose.one");
// Get all Image nodes
IList<Aspose.Note.Image> nodes = oneFile.GetChildNodes<Aspose.Note.Image>();
foreach (Aspose.Note.Image image in nodes)
{
using (MemoryStream stream = new MemoryStream(image.Bytes))
{
using (Bitmap bitMap = new Bitmap(stream))
{
// Save image bytes to a file
bitMap.Save(String.Format(dataDir + "{0}", Path.GetFileName(image.FileName)));
}
}
}Shows how to get image’s meta information.
// The path to the documents directory.
