Question

Can I read and preview fonts (mainly ttf and otf) in C#? What other languages can/should I use?

• Info like font family, font name

Answer 1

Caution: don't use System.Drawing / System.Windows.Forms if you want to preview OTF fonts. Unless they're TTF's in disguise, you won't get them to show. System.Drawing, based on GDI+, only supports TTF fonts!

However, if you can use .NET 3.0, you could use

Fonts.GetFontFamilies(location)

from System.Windows.Media namespace (just reference PresentationCore.dll).

From a FontFamily, you can get the individual Typefaces (.ttc files contain more than one 'font', but a FontFamily also combines the various weights and variants). And from a Typeface, you can call TryGetGlyphTypeface to get the GlyphTypeface, which has a CharacterToGlyphMap property, which should tell you which unicode codepoints are physically supported.

It also seems possible to use GlyphTypeface directly, but I see no way that you can handle .ttc files. However, if that's not relevant, just create a GlyphTypeface per file.

I'd advice against trying all Unicode codepoints sequentially though.

To preview a font you can render it out to a form like this:

public partial class MyForm: Form
{
   .
   .
   .
   public void ShowMyFont()
   {
      Graphics graphics = this.CreateGraphics();
      graphics.DrawString("Hello world!", new Font("Arial", 12), Brushes.Black, 0, 0);
   }
}
