Bitmap fonts - s76/libgdx GitHub Wiki

LibGdx makes use of bitmap files (pngs) to render fonts. Each glyph in the font has a corresponding TextureRegion.

BitmapFont class code

Tools for Creating Bitmaps

Hiero - a utility for converting a system font to a bitmap

Glyph Designer - a commercial bitmap font tool with a wide variety of options for shadows, gradients, stroke, etc.

Other Tools

FreeTypeFontGenerator - generating bitmaps for fonts instead of supplying a pre-rendered bitmap made by utilities like Hiero

Distance field fonts - useful for scaling/rotating fonts without ugly artifacts

gdx-smart-font - unofficial libgdx addon for automatically generating and caching bitmap fonts based on screen size. (Uses FreeTypeFontGenerator)
