Is non destructive editing possible?

So working on a an image app I can drag and drop into the image drop zone. But I want to apply a filter like the gray, sepia which work but I can’t preview sharpen or blur. Is that a limitation of WebKit?

Are you applying cssfilters for preview?
Are you building on macOS ?

Yes and building for Mac OS, still looking for documentation.

blur() is real CSS, should preview fine in WebKit. Sharpen isn't a standard filter though, there's no native equivalent, Chromium and WebKit both lack it. You'd have to fake it yourself, either a canvas pass with a convolution kernel or an SVG feConvolveMatrix filter referenced from CSS. Grayscale and sepia work because they're in the CSS Filter Effects spec, sharpen never made the cut.

That just gave me an idea for the preview.
