Strange anomaly's on crispEdges

[bend-n]

when rendering the result is

please note the upper right anomaly. It also occurs for other files: again, look at the top right.

I have other examples in which it is not just the top right, but i think this will be sufficient.

these are produced with resvg -w "64" -h "64" --shape-rendering crispEdges "svg_file.svg" "out_file.png"

when not using crispEdges, it does not produce any anomaly's, however it anti aliases the image, which is contrary to my wishes.

~~Can you provide the file itself?~~ Found.

any news?

Only after the war in my country will end.

[bend-n]

Okay

Only after the war in my country will end.

I hope to end the war soon. Please be sure to protect yourself!

Are you and your family safe? 🙏 I've noticed you started programming again

@hortiSquash Depends on how you look at it. I live in a city that is shelled by Russians for the past 200 days, everyday. But hey, it could be way worse. At least I'm not on occupied territories, or even dead.

@RazrFalcon Do you have any idea why this could be happening?

[RazrFalcon]

Probably tiny-skia bug. It would take a while to debug. Assuming this is not Skia bug to begin with.

[bend-n]

Let me check.

Okay, so I have news.

Works, with no artifacts (with resvg). Perhaps the svgs need to be de-complexified beforehand?

Seems not to be a skia bug judging from jsfiddle/y5uh7w8f on chrome.

This is definitely a tiny-skia bug. Not sure when I would have time to dive into debugging. It would probably take a whole day.
