Server Side Fonts

Overview

• The Windows Server Core container that root filesystem for TAS is based contains very little system font files
• This becomes an issue for any server side file generation that relies on font files, such as PDF's and Word Doc files
• The following guide offers a workaround to manually load system fonts

Locate and copy necessary font files

• Open File Explore and navigate to C:\Windows\Fonts on your desktop
• Copy files the app needs

Add font files to the project

• Create a directory for fonts such as SystemFonts
• Paste the copied font files into that directory

Create App_Start\FontLoader.cs

using System;
using System.IO;
using System.Runtime.InteropServices;

namespace OnboardingApp.App_Start
{
    public class FontLoader
    {
        [DllImport("gdi32.dll")]
        static extern int AddFontResource(string lpFilename);
        public static void AddFont(string fontFilePath)
        {
            AddFontResource(fontFilePath);
        }

        public static void Load(string fontDir)
        {
            var files = Directory.GetFiles(fontDir);

            foreach (var file in files)
            {
                AddFont(file);
            }
        }
    }
}

Update Global.asax

namespace OnboardingApp
{
    public class Global : HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {
            // Code that runs on application startup
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);

            // load all font files in the directory into the system fonts table
            FontLoader.Load($"{AppDomain.CurrentDomain.BaseDirectory}\\SystemFonts");
        }
    }
}
