Examples
Shows how to add a thumbnail to a document that we save as an Epub.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Writeln("Hello world!");
// If we save a document, whose "Thumbnail" property contains image data that we added, as an Epub,
// a reader that opens that document may display the image before the first page.
BuiltInDocumentProperties properties = doc.BuiltInDocumentProperties;
byte[] thumbnailBytes = File.ReadAllBytes(ImageDir + "Logo.jpg");
properties.Thumbnail = thumbnailBytes;
doc.Save(ArtifactsDir + "DocumentProperties.Thumbnail.epub");
// We can extract a document's thumbnail image and save it to the local file system.
DocumentProperty thumbnail = doc.BuiltInDocumentProperties["Thumbnail"];
File.WriteAllBytes(ArtifactsDir + "DocumentProperties.Thumbnail.gif", thumbnail.ToByteArray());
