TinyHtml.Wpf 1.1.0

TinyHtml.Wpf

Introduction

TinyHtml.Wpf is a WPF HTML rendering library based on litehtml. It provides the rendering backend for WPF. Contrary to similar libraries it uses native WPF drawing to render texts, images and other stuff. So it is fully capable of doing high dpi and blends seemlessly with other content.

Originally it was developed by me to replace HTMLayout that we used before. However text rendering was always blocky and didn't blend well with other WPF content. We use this extensively for dynamic formatted text that is authored as HTML.

This library does not provide scripting capabilities or very advanced HTML. It proved to be quite capable nonetheless.

A Nuget package can be found on nuget.org. It supports x86 and x64 (or AnyCPU) applications.

Requirements

• .NET 4.6
• A WPF application
• Visual Studio 2017 for building

Supported features

• WPF Text rendering
• HTML Tables
• HTML Lists
• Images
• css
• and much more...

Building

1. Get sources from https://github.com/fsdsabel/TinyHtmlWpf: <br/><pre><code>git clone --recursive https://github.com/fsdsabel/TinyHtmlWpf.git</code></pre>
2. Open the Solution TinyWpfHtml.sln in Visual Studio 2017
3. Compile configuration Release - x86
4. Compile configuration Release - x64
5. Binaries should be in Bin directory and HtmlTestApp should run

Usage

Basically there is only one class you need. It is WpfHtmlControl which is subclassed from a standard WPF Control. This control loads a default master style sheet. If you want a custom one, you can derive from WpfHtmlControlBase and load your own.

The master style sheet is used for all the default HTML elements like paragraphs or bold elements. For example you could do something like this:

public class MyWpfHtmlControl : WpfHtmlControlBase
{
    static MyWpfHtmlControl()
    {
        using (var s = typeof (MyWpfHtmlControl).Assembly.GetManifestResourceStream(typeof (MyWpfHtmlControl), "master.css"))
        {
            SetMasterStylesheet(new StreamReader(s).ReadToEnd());
        }
    }
}

You would then use MyWpfHtmlControl in your application.

The most basic usage of a WpfHtmlControl would be:

<local:WpfHtmlControl Background="Blue" Foreground="Red" FontSize="16" 
                      Html="&lt;b&gt;Hello world!&lt;/b&gt;"></local:WpfHtmlControl>

It is possible to bind to the Html property to update the displayed HTML dynamically.

If you want to display images, you have to override OnLoadResource.
