Exception thrown when no font element present in svg

[nzbart]

I have an svg that renders correctly in Inkscape, but causes svg2ttf to throw the following exception:

var fontFaceElem = fontElem.getElementsByTagName('font-face')[0];
                              ^                                   
TypeError: Cannot call method 'getElementsByTagName' of undefined 

There is no font element in the svg, which is below:

Is it valid to have the missing font element, and should svg2ttf cater for this scenario?

That's not font, that's simple svg image. Of cause, it can't be converted.

svg2ttf requires valid svg font on input.

I was mislead by the description of this project, which says

svg2ttf converts SVG graphics to TTF format.

Now that I have read your feedback and re-read the Readme, the only clue that would suggest to me that the "SVG graphics" must actually be an "SVG font" is the name of the svgFontString variable in the API.

[puzrin]

Yes, description is not enouth good.

[tfburton]

This got me too

Thanks for reminder. I've updated description & improved error message. If you need generator from icons - try to search "dependens" of this project on npm https://www.npmjs.com/package/svg2ttf
