AutoTracer QGIS 4 compatibility
QGIS 4 ready Active
Yes — AutoTracer supports QGIS 4 (declared max version 4.99.0).
Converts scanned, georeferenced raster maps into clean line vector layers using binarization, thresholding, smoothing, skeletonization, and vectorization.
About
This plugin automates the conversion of scanned raster maps into vector line features through a multi-step pipeline: 1. Binarization (1-bit black & white conversion) 2. Thresholding (contrast adjustment) 3. Smoothing (noise removal via Median/Gaussian filter) 4. Skeletonization (single-pixel line thinning) 5. Vectorization (raster lines to vector paths)
