The example even not work,

[orklann]

var notdefGlyph = new opentype.Glyph({
    name: '.notdef',
    unicode: 0,
    advanceWidth: 650,
    path: new opentype.Path()
});

var aPath = new opentype.Path();
aPath.moveTo(100, 0);
aPath.lineTo(100, 700);
// more drawing instructions...
var aGlyph = new opentype.Glyph({
    name: 'A',
    unicode: 65,
    advanceWidth: 650,
    path: aPath
});

var glyphs = [notdefGlyph, aGlyph];

// Log out `A` path, which result NaN
console.log(aGlyph.getPath());

var font = new opentype.Font({
    familyName: 'OpenTypeSans',
    styleName: 'Medium',
    unitsPerEm: 1000,
    ascender: 800,
    descender: -200,
    glyphs: glyphs
    });
font.download();

And the A glyph's path are all NaN

Output

[Log] Path (index.html, line 28)

commands: [{type: "M", x: NaN, y: NaN}, {type: "L", x: NaN, y: NaN}] (2)

fill: "black"

stroke: null

strokeWidth: 1

What am I doing wrong?

Hi!

Are you using the latest version on npm or the master branch maybe? In the browser or with Node.js (Which version?)

Also if you could join a full example as a gist it would help ;-)

@Jolg42 Sorry for the long waiting, I am busy these few days.

I make a repo which is very simple demo for showing this issue, please have a check.

Opentype.js Demo

Open the html, and check the console.
