Description

[sisp]

Thanks for your contribution, @adsingh14! 🙏

I see some notable differences between the original icon (black-cutout.svg in the "STANDARD" .zip file) and yours:

Could you please give it another try? It might help to perform the conversion with the highest possible precision your SVG editor supports and let SVGO/SVGOMG perform the precision reduction afterwards.

@sisp Can you please check the attached image?
On the right side, I overlapped my version over the original icon and on the other side, I overlapped the original-on-original icon.

I don't know how you created the diffs, but mine shows some non-negligible differences. I used Boxy SVG, imported the original icon, converted it with maximum precision, imported yours, and computed the diff using the Exclude operation.

I think the small difference can be accepted. I tried to scale it a lot. But the difference is still very thin.

@LitoMore I think the difference is more visible at the edge of the circle. 🤔 Curves and arcs are sometimes difficult to convert accurately with reduced precision. I'm not opposed to accepting the current icon if you think it's sufficiently accurate.

@sisp Ah, you are right. Let me try to process one and see what happened.

I don't know how you created the diffs, but mine shows some non-negligible differences.

I'm pushing the same icon, again, after checking via Boxy SVG

@sisp I tried with precision 5 but still have problems. I think we can consider it good enough.

@LitoMore @adsingh14 Alright then, let's keep it as it is now.
