API Examples

Read font description

FontDescription description = null;
using(var fs = File.OpenRead("Font.ttf")){
    description = FontDescription.Load(fs); // once it has loaded the data the stream is no longer required and can be disposed of

string name = description.FontName(CultureInfo.InvariantCulture);

Populating a font collection

FontCollection fonts = new FontCollection();
FontFamily font1 = fonts.Add("./path/to/font1.ttf");
FontFamily font2 = fonts.Add("./path/to/font2.woff");
