Shows how to extract an embedded font from a document, and save it to the local file system.

Document doc = new Document(MyDir + "Embedded font.docx");

FontInfo embeddedFont = doc.FontInfos["Alte DIN 1451 Mittelschrift"];
byte[] embeddedFontBytes = embeddedFont.GetEmbeddedFont(EmbeddedFontFormat.OpenType, EmbeddedFontStyle.Regular);
File.WriteAllBytes(ArtifactsDir + "Alte DIN 1451 Mittelschrift.ttf", embeddedFontBytes);

// Embedded font formats may be different in other formats such as .doc.
// We need to know the correct format before we can extract the font.
doc = new Document(MyDir + "Embedded font.doc");

Assert.IsNull(doc.FontInfos["Alte DIN 1451 Mittelschrift"].GetEmbeddedFont(EmbeddedFontFormat.OpenType, EmbeddedFontStyle.Regular));
Assert.IsNotNull(doc.FontInfos["Alte DIN 1451 Mittelschrift"].GetEmbeddedFont(EmbeddedFontFormat.EmbeddedOpenType, EmbeddedFontStyle.Regular));

// Also, we can convert embedded OpenType format, which comes from .doc documents, to OpenType.
embeddedFontBytes = doc.FontInfos["Alte DIN 1451 Mittelschrift"].GetEmbeddedFontAsOpenType(EmbeddedFontStyle.Regular);

File.WriteAllBytes(ArtifactsDir + "Alte DIN 1451 Mittelschrift.otf", embeddedFontBytes);
