``bash`

This library takes some elements in a SVG file, rasterizes them using LibRsvg, and replaces the original elements with tags with data uris.
It uses Sharp to create WebP images from the PNG output of LibRsvg.
#### Filter
You can select which elements to rasterize by using the filter option. This library uses Cheerio, which has the same API as jQuery.
The CLI uses this function by default, which selects all elements with an id that have no children with ids:
`javascript`
function($) {
const x = $('*[id]:not([id$="!"])').toArray();
return x.filter(el => !$(el).children('*[id]:not([id$="!"])').length);
}
If librsvg has to be built from scratch, libffi must be installed on your system, and in your PKG_CONFIG_PATH.
`bash`
export PKG_CONFIG_PATH="/usr/local/Cellar/libffi/3.2.1/lib/pkgconfig:${PKG_CONFIG_PATH}"
- No transforms on elements that are rasterized, nor on their parents.
- Support transform (very common on Inkscape files)
Applies to leaf-with-id and leaf-with-id-illustrator:
- Id ends with @: do not rasterize&
- Id ends with : force rasterize!`: act as if no id
- Id ends with
