💡 SVGcode (svgco.de/) is mega slow in Safari/Firefox. I now know why: Safari doesn't support
CanvasRenderingContext2D.filter
at all❗️ (bugs.webkit.org/show_bug.cgi?id=198416) and Firefox doesn't support it w/ SVG filters (bugzilla.mozilla.org/show_bug.cgi?id=1755678). Demo: canvas-svg-filter.glitch.me/. -
I use
CanvasRenderingContext2D.filter
to apply anfeComponentTransfer
filter that posterizes the input image, which makes it feasible to trace. This filter just never kicks in on Safari/Firefox. Try it by loading SVGcode with the?debug
query param: svgco.de/?debug.
