Vecto v0.4.2

Second public release of Vecto — free open-source PNG/JPG to SVG vectorizer for Windows.

Planar image tracing: every boundary between two shapes is fitted once and shared, so the output has no hairline gaps or overlaps. Straight edges become true lines, circles become exact arcs, edges are placed with sub-pixel precision. Dark designer UI with live side-by-side compare, plus a headless CLI.

What's new

Sub-pixel corners. Corners no longer sit on the pixel grid. Each validated corner moves to the intersection of least-squares lines fitted to its flanks, straight sides are fitted as a single shared line from both ends, and directions within 1° of a 45° multiple snap exactly. An anti-aliased box with edges at fractional positions now traces to exactly four mathematically axis-aligned lines, within ~0.001 px of the true edge positions. Across the ground-truth benchmark, mean colour error drops 1–7% and the large-error tail 4–10%.

Two known limits, both tracked in the ROADMAP: junctions where three or more regions meet are still pinned to the pixel lattice, and corners whose anti-aliasing chamfers them can escape corner detection entirely.

Portable mode. A portable.txt file beside Vecto.exe makes the app keep settings.json in its own folder instead of %APPDATA%. The portable ZIP ships with the marker in place — delete it if you would rather have settings in %APPDATA%\Vecto.

MSIX package. A signed sideload package is now built alongside the other artifacts, ahead of a Microsoft Store submission.

App and CLI. PNG export of the traced result; a Nodes view drawing every path outline with node markers; persistence of the last-used palette, style and detail plus window size and state; and a CLI batch mode that accepts wildcards and an --out-dir.

Install

• Vecto-0.4.2.exe — the desktop app, single file, self-contained (no .NET needed). Download and run.
• Vecto-0.4.2-win-x64.zip — portable: the app, the vecto CLI in cli\, and the portable marker.
• Vecto-0.4.2-windows-x64.msix — sideload package. Import Vecto-msix-signing.cer into Local Machine -> Trusted People once, then double-click the MSIX.
• vecto-0.4.2-linux-x64, -osx-x64, -osx-arm64 — the headless CLI, self-contained. chmod +x and run.
• Or build from source: see the README.

Windows SmartScreen may warn on first run (new, unsigned executable): More info -> Run anyway.
