LiberationSans-Regular fonts 404 (Not Found)

[pendelru]

The entire QR-bill shows up but the fonts cannot be loaded:

GET https:///app/vendor/bundle/ruby/3.0.0/gems/qr-bills-1.0.9/web/assets/fonts/LiberationSans-Regular.woff net::ERR_ABORTED 404 (Not Found)
GET https:///app/vendor/bundle/ruby/3.0.0/gems/qr-bills-1.0.9/web/assets/fonts/LiberationSans-Regular.ttf net::ERR_ABORTED 404 (Not Found)

Code:
params[:output_params][:format] = "html"
@Bill = QRBills.generate(params)
<%= raw @Bill[:output] %>

Can anybody help?

I assume you want to embed the HTML output in a website. For that, the fonts need to be served by your web server. If you use Rails and sprockets, you need to copy the fonts to your assets/fonts directory.

In addition, you need to configure qr-bill to use those font paths:

  params[:fonts][:eot] = font_url('LiberationSans-Regular.eot')
  params[:fonts][:woff] = font_url('LiberationSans-Regular.woff')
  params[:fonts][:ttf] = font_url('LiberationSans-Regular.ttf')
  params[:fonts][:svg] = font_url('LiberationSans-Regular.svg')

The URLs here have to be publicly available, as the browser will try to fetch them.
