'Leaking' hachures in nested polygons

jwoLondon opened this issue 3 years ago · 4 comments

Likely related to #165 and #167: For nested holes and islands when setting combineNestedSvgPaths: true, I see leaking of the hachures at the moveTo vertex of each sub-path.

See this interactive minimal reproducible example

As an aside, I only recently discovered the combineNestedSvgPaths option by looking at the source code. I couldn't see it in the API documentation. I may have missed it, but it would be nice to have the option of setting the type of fill rule (non-zero; even-odd; always).

Any fill style is affected.

I'd love to see a fix for this. Currently, combineNestedSvgPath cannot really be used due to this.

I'm working on improving algorithm to support this. Sorry for the late response. Infant baby = neglect open source :(

Will merge and release after some more testing

Fixed by #195 Releases as v4.5.0 on npm.
Note roughjs only does even-odd fills. The combineNestedSvgPaths was a stop gap hack, which is why it was not documented. That property is ignored now.
