d2fonts

The SVG renderer embeds fonts directly into the SVG as base64 data. This is to give deterministic outputs and load without a network call.

To include your own font, e.g. Helvetica, you must include the Truetype glyphs:

• ./ttf/Helvetica-Bold.ttf
• ./ttf/Helvetica-Italic.ttf
• ./ttf/Helvetica-Regular.ttf

You must also include an encoded version of these of mimetype application/font-woff:

• ./ttf/Helvetica-Bold.txt
• ./ttf/Helvetica-Italic.txt
• ./ttf/Helvetica-Regular.txt

If you include a font to contribute, it must have an open license.
