Overview
VS Artwork Vectorizer quantises a raster image into a configurable number of colors, traces polygon boundaries, smooths them into Bezier curves, and assembles the result into a U3M file. A preview step lets you check the vectorization before importing.
Requirements
VStitcher 2025.3.0 or newer (BwApi 3.x)
Maximum image size: 6 MP (e.g. 3000×2000) — larger images are rejected with a clear error
JPEG input is supported on macOS and Windows only; convert to PNG first on other platforms
How to Vectorize Artwork
Step 1: Select an Image
Click Plugins → VS Artwork Vectorizer and browse to a JPEG, PNG, or BMP file. Optionally click Remove Background to flood-fill erase the background.
Step 2: Adjust Settings
Setting | Description |
Color count | Number of quantised colors in the output (2–32) |
Smoothness | Bezier tension and simplification level |
BG Tolerance | Flood-fill color distance for background removal (5–80) |
Step 3: Preview and Import
Click Preview Vectorization to inspect the SVG, then Import as Vector (SVG) for a true vector U3M, or Import as PNG (Raster) to import the raster image directly.
Troubleshooting
Issue | Fix |
Colours look brown/shifted on 3D garment | Confirm Overlay blend mode is active |
Transparent areas render opaque | Alpha threshold may be too low |
Jagged outlines on garment | Increase the Smoothness slider |
JPEG vectorization fails on Linux | Not a supported platform for JPEG — convert to PNG first, or use Raster mode |
If Import fails silently | Check if all the files are that the required plugin files are available in the folder. |
