The background will always show through in betweem two objects with perfectly matching shapes due to how anti-aliasing works.
You need to either switch off anti-aliasing,
or trick the renderer to display more aliased edges -by duplicating the objects atop eachother
or by adding an outline which cover the edge.
Personally I prefer to draw things as they were cut off of paper and one piece was glued next to another one -the bottom one overlapping the top one's edge. Can get quite tedious and tricky sometime. It's the necessary line if you aim for pixel perfect drawings.
I tend to do what Lazur does, seems to work the best. But other workaround methods are to do path offset which usually fills in the gap; or just extend that line a bit. Sometimes adding a stroke works too; or a path>union or join nodes with a new segment might work. It just depends on what you are working on.
Thank you for your reply. This gap issue arises after the Cut Path operation. The gap can only be viewed in outline mode at the maximum zoom level. My workaround for this issue is I insert a node in each path intersection, break the node and delete the excess segment. The problem with this technique is that it can be a little bit laborious.
yes, laborious. It would be nice if Inkscape had that same feature that Gimp uses where you can change the cut path outline, in or out by however many pixels you want. Then magically no gap... wishful thinking!
Tyler, while I agree that it's quite small, it drives me nuts! To me it's noticeable, it just subliminally pulls the eye to it, esp on a dark background.
and ps I've been playing around with the polygon/voronoi diagram tool (there's a vid tut) where you fill in the triangles and delete the outline, which creates a noticeable gap, so if you figure out how to fill in the gap, it works for multiple things. For me, the path>offset works perfectly to fill it in.
When I test it, and zoom to the maximum, the gap is much smaller - just the typical anti-alias issue. I suspect the problem is happening as a result of how cqy20952 performed the operation. But the possibilities are too many to spend time guessing. That's why I asked to see the SVG file.
This is the only guess I will make. The original leaf shape started out as a circle or ellipse, and we have seen discrepancies with ellipses and path operations in the past. It's fixed in 1.0 beta, but we don't know what version was used. If that's not it, I would need to see the SVG file, to sort it out.

In the OP's case, there would be no visible gap, as the paths are stroked.
The voronoi exercise may be a different issue altogether.

How to perform Cut Path without a gap?
The gap can be viewed in outline mode.
Thank you.
Hi,
I do not understand your question. Can you try say it in other words please?
You can also add pictures, so that the people that try to help, will understand the question better.
Hi.
My guess is you experience the "gap issue".
The background will always show through in betweem two objects with perfectly matching shapes due to how anti-aliasing works.

Sharing an SVG file which shows the problem can prevent us from guessing. The 2nd message of this topic tells how to attach an image or file: https://inkscape.org/forums/questions/how-to-make-a-screenshot-and-put-it-in-a-message/
Thank you for replies and sorry for the short message.
Suppose I'm creating a leaf.
I'm going to duplicate the red stroke and cut path over the combined squares.
After the operation, in outline mode when zoomed, you'll notice the gap at the edge of the leaf.
That's a much wider gap than we would expect. Can you share the SVG file? It would be faster than us asking a lot of questions and guessing.
Zoom level is 25600...
Yes, it should be zoomed to the maximum to see the gap.
I tend to do what Lazur does, seems to work the best. But other workaround methods are to do path offset which usually fills in the gap; or just extend that line a bit.

An infinitesimal gap on a 0.5m drawing? Does that need solving?
Too small to measure without scaling up. At 100x scaling, it is less than a mm. Size as originally drawn: 0.0087335803 mm (or <9 microns).
Have a nice day.

Maybe try to adjust the numeric precision in the settings? Edit > Preferences > Input/Output > SVG output.
Wow, so it is fixed in 1.0 beta. Ya, the leaf shape started as an ellipse.
We don't know if it is fixed. It might just be the numeric precision in your preferences.
I always delete preferences.xml so my preferences are always at default.
You can still increase the precision, if you need it to be higher.
In the OP's case, there would be no visible gap, as the paths are stroked.

Maxed precision but no luck.
Just tried using 1.0beta1_2019-09-17 and I think it is fixed.
