I recently got myself a Yubikey and wanted to set up the Yubico Authenticator with all the OTPs I had in Google Authenticator. Unfortunately Yubico Authenticator doesn't support scanning the QR-code that the Google Authenticator generates when you export the OTP-keys, and it seemed like quite the daunting task to log in to every service to generate new OTP-keys. So I decided to have a look at the contents of the QR code, to see if I could import the keys into Yubico Authenticator in one go. Luckily I found a blog post by Alex Bakker that describes the data format.

A list of all the properties for the Document Definition objects in PDF Make. Gathered from the examples source code. Up to date for version 0.1.38.

• The Document Definition is a javascript object: {}. It can contain the following.
• content: array. This defines the layout of your document. All your tags will be defined in there. You define tags using object (e.g. content: [{text: 'Hello World'}])
• styles: object. A dictionary of all the named styles in your document. You can then apply a style to any object using style: 'name' or style: ['name1', 'name2']
• defaultStyle: object. Defines a style to be applied to every element in the document.
• images: object. Another dictionary that you can use to specify all the images in your document.
