\"f7b-colour\"
\nA minimally-useful tracing of the standard numerals embossed
\non credit cards. The geometry should be checked against ISO\/IEC 7811—1:2002 should these data be used for official purposes. No claims of compliance are made here.<\/p>\n

As there are only 10 digits in this font, encoding it as a digital
\nform (TTF, OTF, or otherwise) is left as an exercise for the reader.<\/p>\n

Files<\/h2>\n
    \n
  1. f7b-colour.svg<\/a><\/em> – an A4 sheet with all 10 digits presented as a
    \nposter. Each digit is approximately 1284% standard size.<\/li>\n
  2. eps<\/em> folder<\/a> – PostScript source files. Each outline is approximately 5695% standard size, which is appropriate for a glyph in FontForge<\/a>.<\/li>\n<\/ol>\n

    Workflow<\/h2>\n

    The rough character outlines were created as short scripts in Python,
    \nusing the     Shapely<\/a> library to handle geometry. A confusing array of support tools (including, but not limited to: QCAD<\/a>, wellknown<\/a>
    \nand     OGR<\/a> added the arcs and fillets. The more complex arc intersections were calculated using GeoGebra<\/a>. Finally, the
    \noutlines — at this point, mostly in the form of PostScript Level 2
    \narct<\/strong> commands — were hand-keyed into the EPS files included here.<\/p>\n

    Notes on the data<\/h2>\n
      \n
    1. There are some typos in the published coordinates, particularly in
      \nthe “1” glyph. Whether these are genuine errors or
      \n‘      trap streets<\/a>‘, is hard to tell. The glyphs presented here are intended to be visually accurate<\/li>\n
    2. The published coordinates of the “8” glyph indicate that it is
      \nonly 97.6% as tall as the other digits. This has been carried
      \nthrough here.<\/li>\n<\/ol>\n
