TTFToBitmapConverter — wiki

This is a simple conversion script to convert TTF fonts to a plain Bitmap font table. 

import sys
import pygame

pygame.init ()

if len (sys.argv) < 4  or sys.argv[3] == sys.argv[1]:
    print "usage: %s fontfile size bitmapfile" % sys.argv[0]
    sys.exit ()

filename = sys.argv[1]
size = int(sys.argv[2])
outname = sys.argv[3]

font = pygame.font.Font (filename, size)

strings = [ "0123456789",
            "ABCDEFGHIJ",
            "KLMNOPQRST",
            "UVWXYZ \xc4\xd6\xdc",
            "abcdefghij",
            "klmnopqrst",
            "uvwxyz \xe4\xf6\xfc",
            ",;.:!?-+()"
            ]

surface = pygame.Surface ((len (strings[0]) * size, len (strings) * size),
                          depth=32)
surface.fill ((0, 0, 0))

for y, s in enumerate (strings):
    for x, c in enumerate (s):
        sf = font.render (c, True, (255, 255, 255))
        surface.blit (sf, (x * size, y * size))
pygame.image.save (surface, outname)
The strings table and colours can be changed as needed
