Branding

Although you can style the elements and relationships on your diagrams, you can additionally apply some branding to the diagrams and documentation; including:

  • Font (name and optional web font URL)
  • Logo (URL to a PNG/JPG/GIF image file, or a data URI representing the image in base64 format)

Notes

When specifying the logo as a URL, if you are using the cloud service, the logo must be served over HTTPS. Also, for security reasons (see Allowing cross-origin use of images and canvas for more details), the web server hosting your logo must set the Access-Control-Allow-Origin header to allow cross-origin requests. Failure to have this header will mean that the process of exporting your diagrams to PNG will fail.

To avoid these problems, you can instead specify your logo as a base64 data URI instead. You can find utilities to convert an image file to a base64 encoded data URI in the Java/.NET client libraries, and online.
