I need to get Windows fonts to work in a docker Linux container but first, before I try that, I’m seeing if I can test with embedded fonts on Windows when the font is not installed on windows. I’m running this on Windows 10, .Net Core 3.1, in Visual Studio 2019, and Aspose.PDF for .Net 22.6.0.
So, I downloaded a font which is not installed on windows and embedded it in a resource on my unit test just to try it. This didn’t work with any font I tried it with. I tried upper case, lower case, etc. for the font name. I opened the font and looked at the font name stored just to double check.
I tried the “Short Baby” font from this page since it’s unlikely to be installed already

[TestMethod]
public void LoadFontResources()
{
// Retrieve a list of embedded fonts
var fontNames = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames().Where( name => name.ToLower().EndsWith( "ttf" ) );
Stream fontStream;
foreach ( var fontName in fontNames )
{
Console.WriteLine( $"Loading font {fontName}");
// Test to see the name and ensure it is valid
fontStream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream( fontName );
Aspose.Pdf.Text.Font fontA = FontRepository.OpenFont( fontStream, FontTypes.TTF );
fontStream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream( fontName );
using ( var ms = new MemoryStream() )
{
fontStream.CopyTo( ms );
var fontSource = new MemoryFontSource( ms.ToArray() );
// Verified that the fontSource does have the array of bytes for the array loaded.
FontRepository.Sources.Add( fontSource );
// Didn't work here either
//var font1 = FontRepository.FindFont( "Short Baby" );
}
}
//FontRepository.ReloadFonts(); // Not sure if this is needed, tried with and without
// Test to see if it worked. It does not.
// Tried "Short Baby", "ShortBaby","shortbaby","short baby","ShortBaby-Mg2w"
var font2 = FontRepository.FindFont( "Short Baby" );
}
I added an OpenFont statement just to verify the font loads and the name used. I attached a debug screenshot for this example.
