Just wanted to give a shout out to Hiero, an outstanding bitmap font generator! It will convert any TTF system or file font to a format compatible with LibGDX. It will even apply some minor effects to the glyphs, such as outlines, shadows, and gradients. Use it for other engines as well, provided that you can ready their .fnt format.
For instance, this is Franklin Gothic Heavy at size 32 with a shadow, outline and gradient, squished into a 256×256 square. SUPER helpful!
