AutoTrace vs WinTopo

AutoTrace converts bitmap images into vector graphics, with tracing options for outlines or centerlines. It can reduce colors and despeckle images to reduce noise, and its listed maximum color count is 256. Input formats include PNG, BMP, TGA, PNM, and GF; ImageMagick or GraphicsMagick can add JPEG, TIFF, GIF, and other formats. Outputs include SVG, EPS, PDF, AI, DXF, CGM, EMF, MIF, ER, and Fig. The project documents command-line conversion and use through the libautotrace library. It is free and listed for Linux, macOS, and Windows. Installation options include package managers for macOS, Linux, and FreeBSD, Windows installers, or building from source. Source builds require a C compiler and GLib 2.58 or newer; libpng and ImageMagick or GraphicsMagick are optional dependencies. The program is licensed under GPL v2 or later, while the library uses LGPL v2.1 or later. The README directs users to the issue tracker and describes the graphical frontend as inactive. Version 0.31.10 is listed as the latest release.

WinTopo is Windows desktop software that converts TIF, JPG, PNG, GIF, BMP files, and scanned images into vector files for CAD, GIS, and CNC applications. One-Touch Vectorisation performs raster-to-vector conversion in a single click. Documented exports include DXF, SHP, PDF, MIF, ARC, DI, WMF, EMF, ASC, and WTX, and batch conversion is available. WinTopo Pro adds image processing, more advanced vectorisation algorithms and options, georeferencing, GeoTIFF coordinate extraction, and manual vector digitising over the raster image. Its trial includes all Pro features, but an unlicensed copy saves only a sample of the vector result. Freeware is unrestricted for small conversion volumes. The first Pro license costs 200.00 GBP once for one computer; an additional license costs 150.00 GBP once. WinTopo generally runs on Windows 7 or higher, with stated approximate minimums of a 1GHz CPU, 0.5GB memory, and 50MB storage.
