The Scrawl-canvas library's filters functionality is inspired by SVG filters. Filter operations can be ordered in ways to combine different sets of operations to achieve complex effects.<p>The library comes with an extensive set of pre-built filters, including: color and alpha channel manipulations; matrix, pixellate, blur; compositing and blending operations; palette reduction and dithering; image and noise asset upload (for use with composites and blends); gradient, and displacement, mapping.<p>Filters can be applied to individual graphical objects, to Groups of such objects, and also to Cell displays.<p>Additional links:<p>- A gallery of SC compound filter effects - <a href="https://scrawl-v8.rikweb.org.uk/demo/filters-103.html" rel="nofollow">https://scrawl-v8.rikweb.org.uk/demo/filters-103.html</a><p>- SC stencil (background) filter functionality - <a href="https://scrawl-v8.rikweb.org.uk/demo/filters-028.html" rel="nofollow">https://scrawl-v8.rikweb.org.uk/demo/filters-028.html</a>
