// clean path geometry · zero raster artifacts · slicer-ready
Most QR code tools — even ones that claim SVG output — produce a grid of individual squares: one <rect> per dark module. That looks fine on screen, but causes real problems in a slicer or CAD tool. Touching rectangles create invisible seams that confuse extruders, leave hairline gaps under certain slicer settings, and cause double-pass burns in laser engravers.
This generator traces the entire QR boundary and merges all adjacent dark regions into single closed <path> polygons with no internal seams. The output is topologically clean geometry — one file, ready to extrude, emboss, or engrave without any post-processing.
Error correction determines how much of the code can be damaged and still scan. Higher correction means more redundancy and a denser code.
