middleman-svg-fallback

Generate nice JPEG and PNG files from any SVG files in your images/ folder.

Also, generate gzipped SVGZ files.

Attention: This requires Inkscape.

Add this line to your Gemfile:

gem 'middleman-svg-fallback'

Activate the plugin in your config.rb:

activate :svg_fallback

You may provide the path to your inkscape binary, if it's not in the PATH. E.g. on macOS, you may use the following configuration:

activate :svg_fallback, inkscape_bin: '/Applications/Inkscape.app/Contents/Resources/bin/inkscape'

Furthermore, you may configure command line arguments, that should be passed on to inkscape:

activate :svg_fallback, inkscape_options: '--export-dpi=100 --export-background-opacity=0'

If configured properly, middleman-svg-fallback will generate fallback images (PNGs and JPGs) for all SVGs within your images_dir as you would expect. You can use them with a modernizr based CSS rule, like this for example:

.illustration {
  background: url('illustration.svg') 0 0 no-repeat;
}

.no-svg .illustration {
    background: url('illustration.png') 0 0 no-repeat;
}

The generated JPEG files are intended for use with OpenGraph. Facebook doesn't like PNGs in og:image properties, so the JPG versions will come in handy.
