Copy Code

Electronic Publications are essentially a package that consists of XHTML, XML and image files and is compressed to a ZIP archive. By default NOV rich text view uses medium compression level when creating the EPUB package. The medium compression level is a nice compromise between speed and compression ratio. If you want to change the compression level of an EPUB package, you should pass an NEpubSaveSettings instance with the proper value set to its CompressionLevel to the Save method.

Saving an Electronic Publication with a different compression level
Copy Code
NEpubSaveSettings saveSettings = new NEpubSaveSettings();
saveSettings.CompressionLevel = ENCompressionLevel.BestCompression;
m_RichTextView.SaveToFile(@"C:\MyBook.epub", new NEpubTextFormat(), saveSettings);
