...it is valid to say that they apply to the object in its own post-transform coordinate system, because that's what the spec says: The ‘transform’ attribute is applied to an element before processing any other coordinate or length values supplied for that element. In the element <rect x="10&q...

...it's not so much that the filter is being applied first, as that the filter is being applied in the new coordinate system introduced by the transform. Whether it's implemented as "render filtered version, then transform" or "transform coordinate system, then render filter" wo...

You could define a fill attribute after a stroke attribute You could do this but it has to mean exactly the same things as defining them the other way around, according to XML rules. That was my point Specs say the transform will be applied after the filter. That's all. Do they? I spent some time l...

Sorry, Xav, I didn't express myself very clearly: that's what I meant. I see your point - sometimes it wouldn't make much sense for the filter to operate post-transform. That sounds to me like an argument for being able to choose the order of filter / transform application, since there are also situ...

Thanks for the links, Lazur. They do seem to suggest SVG as the source of this, but I wonder if it's possible to argue that the spec is ambiguous and, further, that Inkscape has taken the wrong interpretation? primitiveUnits = "userSpaceOnUse | objectBoundingBox" Specifies the coordinate s...

Thanks so much, Xav, that work's perfectly and is appealingly straightforward. Hulf, I tried to experiment with your technique too but for the particular object I'm interested in, I couldn't make interpolate do anything. I assume you meant "Extensions -> Generate from Path -> Interpolate...&quo...

Thanks for your help, Lazur.

Unfortunately, the "Optimized" setting is already set (presumably it's been this way since I installed Inkscape). Shame, as the description of this setting sounds like it should do exactly what I need.

Hi, I've created a custom filter: just a drop shadow (offset, blur, merge; offset and blur have identical X and Y parameters). It isn't behaving as I'd expect / wish. If I have a shape whose size and / or aspect ratio has been altered, the filter does not apply the same as it would to shapes which h...
