Description

ttf2afm gives output that contains widths of all grlyphs. This information is required to embed fonts in PDF.

To calculate the width:

  • Get the unitsPerEm from the head table.
  • Get advanced width for each glyph from the hmtx table.

Calculate:

                     n               remainder(n, unitsPerEm) 1000
        f(n) := (----------) 1000 + ------------------------------
                 unitsPerEm                  unitsPerEm

where n is the advanced width.
