SharpFNT is a C# library for reading and writing AngelCode bitmap fonts (.fnt) in binary, XML, and text. It is built for .NET Standard 1.3 or higher. I have a command line application for converting and inspecting AngelCode bitmap fonts available here.
The following loads a bitmap font from a file, outputs the name of the font, changes the font name, and then saves it as a new binary bitmap font.
using SharpFNT;
BitmapFont bitmapFont = BitmapFont.FromFile("ExampleFont.fnt");
Console.WriteLine(bitmapFont.Info.Face);
bitmapFont.Info.Face = "New Name";
bitmapFont.Save("ExampleFont2.fnt", FormatHint.Binary);
See the documentation for BMFont for information on rendering text and the properties of the file format.
SharpFNT can be downloaded on NuGet or from the releases section.
