fontgen's Introduction

FontGen

A simple utility application that takes a TTF file and converts it into a .pgm along with a text file describing which character maps to which coordinates.

Arguments

TTFFILE: filename of the .ttf (or any other format supported by freetype)
SIZE: size of the font (in pixel?!)
BORDER: an border that is left around each glyph, useful when one wants to add effects such as shadow or a black border
IMAGEWIDTH: width of the resulting image
IMAGEHEIGHT: height of the temporary image (ugly, but needed at the moment)
UNICODES: optional list of characters that shall be generated, default is the whole font

Example

Running:

build/fontgen generate AMRIGOM.TTF  16 2 512 512 "$(build/fontgen listchars AMRIGOM.TTF)"

Will produce a file /tmp/out.pgm:

And a font description /tmp/out.font:

(pingus-font
  (size 16)
  (glyph-count 257)
  (glyphs
    (glyph (unicode 9674) (offset 0 -13) (advance 8) (rect 0 0 12 21)) ;; ◊
    (glyph (unicode 124) (offset 3 -12) (advance 8) (rect 12 0 17 20)) ;; |
    (glyph (unicode 123) (offset 2 -12) (advance 8) (rect 17 0 26 19)) ;; {
    (glyph (unicode 91) (offset 1 -11) (advance 4) (rect 26 0 32 19)) ;; [
    (glyph (unicode 93) (offset 1 -11) (advance 4) (rect 32 0 38 19)) ;; ]
    (glyph (unicode 209) (offset 0 -15) (advance 10) (rect 38 0 52 19)) ;; Ñ
    (glyph (unicode 402) (offset -1 -11) (advance 8) (rect 52 0 65 19)) ;; ƒ
