WPF-Math [![NuGet][badge-nuget]][nuget] ======== *WPF-Math* is a .NET library for rendering mathematical formulae using the LaTeX typsetting style, for the WPF framework. Getting Started --------------- The simplest way of using *WPF-Math* is to render a static formula in a XAML file as follows. ```xml <Window ... xmlns:controls="clr-namespace:WpfMath.Controls;assembly=WpfMath"> <controls:FormulaControl Formula="\left(x^2 + 2 \cdot x + 2\right) = 0" /> </Window> ``` For a more detailed sample, check out the [example project][example]. It shows the usage of data binding and some advanced concepts.  ### Using a rendering API The following example demonstrates usage of `TexFormula` API to render the image into a PNG file using the `RenderToPng` extension method: ```csharp using System.IO; using WpfMath; namespace ConsoleApplication2 { internal class Program { public static void Main(string[] args) { const string latex = @"\frac{2+2}{2}"; const string fileName = @"T:\Temp\formula.png"; var parser = new TexFormulaParser(); var formula = parser.Parse(latex); var pngBytes = formula.RenderToPng(20.0, 0.0, 0.0, "Arial"); File.WriteAllBytes(fileName, pngBytes); } } } ``` If you need any additional control over the image format, consider using the `GetRenderer` API: ```csharp using System; using System.IO; using System.Windows.Media.Imaging; using WpfMath; namespace ConsoleApplication2 { internal class Program { public static void Main(string[] args) { const string latex = @"\frac{2+2}{2}"; const string fileName = @"T:\Temp\formula.png"; var parser = new TexFormulaParser(); var formula = parser.Parse(latex); var renderer = formula.GetRenderer(TexStyle.Display, 20.0, "Arial"); var bitmapSource = renderer.RenderToBitmap(0.0, 0.0); Console.WriteLine($"Image width: {bitmapSource.Width}"); Console.WriteLine($"Image height: {bitmapSource.Height}"); var encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(bitmapSource)); using (var target = new FileStream(fileName, FileMode.Create)) { encoder.Save(target); Console.WriteLine($"File saved to {fileName}"); } } } } ``` You may also pass your own `IElementRenderer` implementation to `TexFormula.RenderFormulaTo` method if you need support for any alternate rendering engines.

WPF-Math requires C# 8 and F# 4.7 support. Here's the build and test script: ```console $ dotnet build --configuration Release $ dotnet test ``` To approve the test results if they differ from the existing ones, execute the `scripts/approve-all.ps1` script using PowerShell or PowerShell Core. To publish the package, execute the following command: ```console $ dotnet pack --configuration Release ``` History ------- The library was originally ported from the [JMathTex project][jmathtex], copyright 2004-2007 Universiteit Gent. The port was originally named *WPF-TeX* and was written and maintained by [Alex Regueiro][alex-regueiro]. It was later available as [*WPF-Math* on Launchpad][launchpad], but was unmaintained from 2011 until it was revived in [its current form][github].
