Intent to Ship: Support for full 'filter' property syntax on SVG elements

Explainer

None

Specification

https://drafts.fxtf.org/filter-effects-1/

Summary

Allows the full syntax of the 'filter' property to be used on SVG elements which previously only supported single url(...) references. This allows filter functions such as blur(...), sepia(...) and grayscale(...) to apply to SVG elements as well as non-SVG elements. It makes the platform support for 'filter' more uniform and allows for easier application of some "canned" effects.

Blink component

Blink>SVG

Search tags

svg filters

TAG review

No TAG review because this is a feature that we already implement, and it has been shipping in Gecko for a number of years already.

TAG review status

Not applicable

Risks

Interoperability and Compatibility

The main risk is the lack of support in WebKit.

Gecko: Shipped/Shipping (https://bugzilla.mozilla.org/show_bug.cgi?id=1057180) (Shipped in FF 35)

WebKit: No signal (https://lists.webkit.org/pipermail/webkit-dev/2020-December/031653.html)

Web developers: Positive Bug currently has 44 stars.

Ergonomics

This addition should generally improve ergonomics because it removes one reason for adding special cases based on which element something will/could apply to. Performance should be in line with the already existing support.

Is this feature fully tested by web-platform-tests?

Yes

BTW, WebKit signals are positive now.

LGTM3

Nice to see this becoming a reliable feature of the web. Once WebKit
implements the final part, is this "done" from the web's point of view?

From a spec (Filter Effects L1) perspective, I guess the answer would be: "Almost done" (the filter() <image> value being the last hold-out)
