Cross-platform FreeType bindings for .NET

SharpFont is a library that provides FreeType bindings for .NET. It's MIT licensed to make sure licensing doesn't get in the way of using the library in your own projects. Unlike Tao.FreeType, SharpFont provides the full public API and not just the basic methods needed to render simple text. Everything from format-specific APIs to the caching subsystem are included.

SharpFont simplifies the FreeType API in a few ways:

  • The error codes that most FreeType methods return are converted to exceptions.
  • Since the return values are no longer error codes, methods with a single out parameter are returned instead.
  • Most methods are instance methods instead of static methods. This avoids unnecessary redundancy in method calls and creates an API with a .NET look-and-feel.

For example, a regular FreeType method looks like this:

Face face;
int err = FT_New_Face(library, "./myfont.ttf", 0, &face);

The equivalent code in C# with SharpFont is:

Face face = new Face(library, "./myfont.ttf");

Quick Start

NuGet

SharpFont is available on NuGet. It can be installed by issuing the following command in the package manager console:

PM> Install-Package SharpFont

From Source

Clone the repository and compile the solution. Copy SharpFont.dll to your project and include it as a reference. On Windows, you must include a compiled copy of FreeType2 as freetype6.dll in the project's output directory. It is possible to rename the file by changing the filename constant in FT.Internal.cs and recompile. On Linux and OSX (and any other Mono supported platform), you must also copy SharpFont.dll.config to the project's output directory.

Mono

With the removal of the WIN64 configurations, the included Makefile is effectively redundant. However, you can still build SharpFont by calling make while in the root directory of this project.

FreeType

A large number of FreeType builds for Windows are now available in the SharpFont.Dependencies repository.

Known Issues

While SharpFont is fully compatible with and runs on 64-bit Windows, it relies on a patch for FreeType to do this. This patch is already included in SharpFont.Dependencies/freetype2. You do not need to worry about this as a user of the library. If you are compiling FreeType from source, you can find the patch and instructions at the same location.
