SVG fills can treat an open contour as closed for the purpose of painting its interior. That can create a diagonal filled region between the path's last and first points, even though no closing stroke is visible. Inspect the endpoints before changing fill rules or repeating Boolean cuts.
Key Takeaways
- An open stroked contour can still produce a filled interior.
- Explicitly closing a path and merely placing endpoints together are different states.
- Use a closed silhouette for filled weapon art and separate open paths for decorative lines.
Reveal the path beneath the paint
Work on a duplicate and use the Node tool to locate the endpoints. Temporarily disable the fill while retaining a visible stroke. The Editing Paths guide explains the difference between open and closed paths. Look for two endpoints that visually meet but remain unjoined.
If removing the fill removes the unexpected diagonal patch, the object may be behaving according to its current open contour rather than suffering from export corruption. Do not erase the rendered patch in a PNG before understanding the source geometry.
Choose the intended topology
For a filled blade silhouette, join or connect the appropriate endpoints to make its boundary explicit. The Node Tool options distinguish joining nodes from adding a connecting segment. Choose the operation that preserves the intended outline; merging distant nodes can pull the tip into the wrong place.
For an engraving or a trailing motion line, an open path with no fill may be correct. Keep it separate from the filled body rather than combining all visible details into one ambiguous contour.
The SVG painting specification states that fills apply to open subpaths as though they were closed for filling. This does not automatically create the same visible stroke join. That distinction explains why the diagonal filled area can appear without a matching outline segment.
| Intended object | Path decision | Paint decision |
|---|---|---|
| Solid blade silhouette | Explicit closed boundary | Fill and intentional outline |
| Decorative engraving | Open line may remain open | Usually no fill |
| Ring-shaped cutout | Deliberate compound geometry | Review fill rule and actual hole |
Inspect a meaningful endpoint example
Consider a proposed, unexecuted icon repair. A curved dagger contour starts at its handle and ends near the upper blade. Filling that open path introduces a straight closing boundary across the artwork. Adding more blade nodes without joining the intended contour can move the diagonal rather than remove its cause.
Restore the intended blade outline, then inspect the handle opening separately. If the hole remains wrong after closure is explicit, investigate compound-path structure and fill rule as a different issue. One global fill-rule change may fix a hole while masking a still-open exterior contour.
Validate before raster delivery
Save and reopen the source, then export at the intended icon size. Check the blade tip, handle opening and any narrow negative spaces against contrasting backgrounds. A successful XML save does not prove the path expresses the desired silhouette.
For related repairs, read Combine versus Union, trace-stage detail loss and stroke cap effects. No Inkscape fixture or renderer execution is claimed. Approve the icon after its contour topology and its visible filled area agree with the design.
