Net::ReadTimeout on Rails 6 with SVG favicon

[amingilani]

Hi, this may be related to #31

I've run through the steps as usual on your site, installed rails_real_favicon in :development, run bundle install and copied the configuration into config/favicon.json with the following:

    "master_picture": "app/assets/images/brand-mark.svg"

However, generating the favicon throws this:

rails generate favicon

This problem did not occur when I converted my SVG image to a PNG image and reran the same steps. It appears as though this gem is not compatible with SVG images.

I can document it for you if you'd point me in the right direction :)

I had the same problem on rails 6, the same application but on rails 5.2 worked fine. Used also svg.

[amingilani]

In that case, this is likely a bug.

Pr #36 fix this problem. You can close it

I did this with a svg and passed -t 90 and it processed everything.
