Import svg patterns

[EricP]

When importing files containing svg patterns, VectorStyler did not render the pattern as expected (nor did Affinity, but Inkscape did render correctly). Is there a setting I missed ?

By pattern, I'm referring to a pattern which can be defined in defs and applied to multiple shapes as a url fill. Like defined in : https://developer.mozilla.org/en-US/docs/Web/SVG/Reference/Element/pattern

Test file :

zipped : 0_1768562757314_test_svg.svg.zip

@VectorStyler release 1.3.008 fixed the pattern import. Thanks for that.

I found an issue, working with imported patterns. They don't seem to behave like native VS patterns and make the imported document difficult to edit.

I think there are 2 main issues remaining :

1/ expanding pattern tiles makes VectorStyler very slow (up to freeze on large designs)

I'm attaching a VS document where a design has been imported from a svg file (with svg pattern).
VS document : 0_1768726791597_imported svg with pattern fill.vstyler

Here is the original imported SVG document : 0_1768726876271_exported (42).svg.zip

After expansion of the pattern into a clipping mask, the object becomes slow to manipulate or recolor. On larger design files, the application simply removes the pattern upon expanding it, or freezes.

Here is an example of a design where VS doesn't expand the pattern at all (leaving it blank) : 0_1768727368297_exported (40).svg.zip

I noticed that imported svg patterns expand into a much more nested grouping structure than native VS patterns, which could explain the slowness

Native VS dot pattern after expansion

2/ render (minor) : imported patterns don't render well, until the canvas is zoomed. Rendering comes and goes as we work on the document and zoom in and out. Not a major issue but would be nice if it could be improved

@EricP I can replicate this last error with the slowdown. The object that was filled with the pattern is large and when expanding creates a lot of small clipping groups.
This is slow to render for now.
I will try to improve this later, but for now I have no solution for this.

The grey fill at zoom out is just for display, the level at which this happens can be set in display options.
