Hey,

I'm trying to use FontAwesome in my noesis project. I put it into our theme like this:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <FontFamily x:Key="FontAwesome">UIAssets/Fonts/FontAwesome.ttf#FontAwesome</FontFamily>
</ResourceDictionary>

Then I'm trying to use it in a label like this:

<Label FontFamily="#FontAwesome" FontSize="{Binding TitleFontSize, FallbackValue=48}">Play</Label>

At first I wasn't sure if that syntax was even going to find the font file but it does.
But then it fails making a font family out of that anyway.
We're getting the following exception:

NoesisException: Assets/MyTheme.xaml(38): Can't convert 'UIAssets/Fonts/FontAwesome.ttf#FontAwesome' into a 'FontFamily' object.

I used the ttf file from: https://github.com/FortAwesome/Font-Awe ... id-900.ttf

What am I doing wrong?

Hi,

I don't know if you renamed it, but if I download the file its name is fa-solid-900.ttf.
And after the # you have to write the font family name exposed by the ttf, in that font it is 'Font Awesome 5 Free'.

The following syntax should work:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <FontFamily x:Key="FontAwesome">UIAssets/Fonts/fa-solid-900.ttf#Font Awesome 5 Free</FontFamily>
</ResourceDictionary>

Apart from that, when using the font, you should reference it as an StaticResource.

<Label FontFamily="{StaticResource FontAwesome}" FontSize="{Binding TitleFontSize, FallbackValue=48}">Play</Label>

Let us know if this works.

Yeah I renamed the file. I used the original file now and still get this error:

NoesisException: Assets/MyTheme.xaml(38): Can't convert '/Assets/UIAssets/Fonts/fa-solid-900.ttf#Font Awesome 5 Free' into a 'FontFamily' object.

NoesisXaml:RegisterDependencies() (at Assets/NoesisGUI/Plugins/NoesisXaml.cs:55)
NoesisXaml:OnEnable() (at Assets/NoesisGUI/Plugins/NoesisXaml.cs:10)

with

<FontFamily x:Key="FontAwesome">/Assets/UIAssets/Fonts/fa-solid-900.ttf#Font Awesome 5 Free</FontFamily>

Could it be that Noesis simply can't find the file and we have to put it into the streaming assets somehow?

I just tried with an absolute path and it works fine also.

Could you verify if the NoesisFont asset was generated for the ttf?
Go to /Assets/UIAssets/Fonts/, right-click fa-solid-900.ttf, and select Reimport. It should generate a fa-solid.asset next to it.
Now got to /Assets/MyTheme.xaml and reimport it too. Is it working now?

There's definitely an .asset file for the font and for the theme xaml too. I get the same error as above when I reimport the theme. :S

I'll try to create a self-contained project to reproduce the issue independently from our project.

Ok, if you can isolate the problem in a small example, could you please report it in our bugtracker attaching that project?
Thanks.
