Emoji.Wpf adds Emoji rendering support to WPF applications.

• Provides drop-in replacements for TextBlock and RichTextBox, no additional code required.
• Colour emoji! 😨 💩 🍰 ✈️ ✏️ 📞 ☘️

• Emoji for flags!
• Win11 style flags!
• Full vector emoji! Render at huge sizes without quality loss.
• Optional support for subpixel antialiasing.
• Lightweight; does not embed a font or emoji images; just uses the system font.
• Works with old .NET versions such as .NET Framework 4.0.
• Can work on Windows 7 or Windows 8 by installing the Segoe UI Emoji font in c:/Windows/Fonts.
• Free, opensource software, with no strings attached.
• Available as a Nuget package.

• Emoji.Wpf.TextBlock: an emoji-aware version of System.Windows.Controls.TextBlock.
• Emoji.Wpf.RichTextBox: an emoji-aware version of System.Windows.Controls.RichTextBox.
• Emoji.Wpf.Picker: an emoji picker

• Emoji.Image.Source: attach to either System.Windows.Controls.Image control or System.Windows.Media.DrawingImage object in order to manipulate emoji images

• bool Emoji.Wpf.EmojiData.EnableSubPixelRendering: enable subpixel rendering, defaults to false
• bool Emoji.Wpf.EmojiData.EnableWindowsStyleFlags: enable flag rendering, defaults to autodetected

Here is how to use Emoji.Wpf in your XAML:

    <Window ...
            xmlns:emoji="clr-namespace:Emoji.Wpf;assembly=Emoji.Wpf"
            ...>
        <Window.Resources>
            <DrawingImage x:Key="MyImageSource" emoji:Image.Source="👻"/>
        </Window.Resources>
        ...
        <emoji:RichTextBox FontSize="24" Margin="5"/>
        ...
        <emoji:TextBlock FontSize="24" Text="Hello! 💖😁🐨🐱‍🐉👩🏿‍👩🏻‍👦🏽 lol"/>
        ...
        <emoji:Picker FontSize="40"/>
        ...
        <Image Source="{StaticResource MyImageSource}"/>
        ...
        <Image emoji:Image.Source="🦑"/>
        ...
    </Window>

More classes are to come, but feedback on what is needed is welcome.

I am not a very good WPF or even C# developer, but I think this could become a very useful and robust library if given enough care. Any help appreciated!

Emoji.Wpf renders emoji as vector images, using the WPF text rendering engine. The geometry information is found in the Segoe UI Emoji font glyphs. The colour information is found in the same font, using Microsoft’s COLR/CPAL format extensions.
