So I created this custom pattern #2548 like shown below, and applied the pattern to a plain circle.

Custom pattern creation and application

Instantly when applying the pattern to the circle, it is applied like five times bigger than it was created. Why is that, and how can I apply a custom pattern in its original size as it has been created to shapes?

Also, when I create a pattern this way and then try to adjust its size or angle with the Node Tool, why is it that the adjusting nodes appear like half a meter off the page?

Nodes for adjusting pattern are way off the page

Is this a bug?

Explanations or help much appreciated.

  • I guess some Inkscape users avoid using pattern fills due the lack of control.You have met a part of it. The fill cannot be expanded to tiled independent shapes and one cannot trust the pattern scaling and placement stays when exported as general (non-Inkscape) SVG. A workaroud is to tile clones and insert a clipping path which is the actual shape to be filled.

Yeah, I've noticed this before especially in Inkscape 1.0. It's quite annoying. I'd say it's probably a bug because I don't remember the problem existing in 0.92.

But anyway, as for a fix, you can click and drag the X to bring the pattern controls closer to your object, and you can adjust scaling and rotation of the pattern using the controls.

For example

And just to check this still renders OK in browsers here's the optimized SVG for that one object I adjusted. Looks OK in Firefox, Chrome and Edge.

Another possible workaround I found is to open the document properties, set units to px, and scaling to 1. This seems to fix the pattern scaling issue. Ultimately, I think this must be the real source of the bug. Changing a documents units shouldn't change the behaviour of Inkscape's patterns.

  • I downloaded and opened your linked SVG in Illustrator. The result was totally different - a solid white circle. Can be caused by the fact I use Legacy stuff. But quite new Affinity Designer showed a transparent circle. Does modern Illustrator show it as intended?

  • @user287001 Illustrator has shockingly bad support for SVG standards. It doesn't seem to be a priority for Adobe. I use Illustrator CC (2018, not the most recent) and it's just as bad. I'm really not surprised it doesn't work. I've never used Affinity Designer. Check the SVG in a browser. It's absolutely fine.

  • Thanks guys, that's very helpful. I already have opened a bug here: gitlab.com/inkscape/inbox/-/issues/4146. On a side note, do you guys have an idea how not to have thin white lines in the pattern as can be seen from Bill's exported SVG here: svgshare.com/i/S71.svg i.imgur.com/IdBg3eV.png

    @David.P these are conflation artifacts. If you want to avoid them, maybe don't use a pattern for this. Instead, just create a pattern of stripes manually, group it with a rectangle filled pink as the background, and set the circle as a clipping mask on the group.
