Several options are available for different use cases: * "Brightness cutoff" detects areas that are darker than the threshold value and creates a path enclosing them (using potrace). * "Edge detection" detects changes greater than the given threshold value in the brightness of color patches and creates paths to separate them (using potrace). * "Color quantization" separates the image into the given number of colors, and separates them with a path (using potrace). * "Autotrace" uses the autotrace algorithm with the given option. * "Centerline tracing" tries to vectorize a line drawing (with autotrace). * "Multicolor" options separate the image into a number of scans, depending on brightness, color separation, or gray levels (using potrace), or using the autotrace algorithm, and create several paths for those. * The "Pixel art" tab allows to use an algorithm for pixel recognition or one for depixelizing to vectorize pixel art images. * NOTE: 1) Save your work before tracing 2) Watch your pixel count: "Trace pixel art" creates up to one path per pixel. It is not recommended for images that are not pixel art. 3) Autotrace is slower than potrace, it is not recommended for big images. Preprocessing your images to increase contrast is recommended. 4) If your goal is to get few nodes and good precision, manual tracing is always best. 300 400 none True True never False True True natural natural False word helptext 5 0.20 0.05 10 1.34 1 0.01 10 1000 2 1 10 True vertical True vertical top True True True start True True start vertical True True start 8 8 4 4 4 Speckles True True Ignore small spots (speckles) in the bitmap start True True 0 10 Smooth corners True True Smooth out sharp corners of the trace start True True 0 11 60 True True True speckles 1 False 1 10 2 True True True smooth False 1 11 2 Optimize True True Try to optimize paths by joining adjacent Bezier curve segments start True True 0 12 True True True optimize False 1 12 2 True start Threshold 0 2 True start Edge threshold 0 3 True start Colors 0 4 True start Filter iterations 0 5 True start Error threshold 0 6 Invert image True True Invert black and white regions start start True 0 7 4 True start Details: 0 9 4 True True SS_AT_ET_T False 1 6 2 True True SS_AT_FI_T False 1 5 2 True True SS_CQ_T False 1 4 2 True True SS_ED_T False 1 3 2 True True SS_BC_T False 1 2 2 True 0 Brightness cutoff Edge detection Color quantization Autotrace Centerline tracing (autotrace) 0 1 4 True start Detection mode: 0 0 4 True True SS_BC_T 3 3 2 True True SS_ED_T 3 3 3 True True SS_CQ_T 3 4 True True SS_AT_FI_T 3 5 True True SS_AT_ET_T 1 3 6 True True Speckles of up to this many pixels will be suppressed speckles 3 10 True True Increase this to smooth corners more smooth 2 3 11 True True Increase this to reduce the number of nodes in the trace by more aggressive optimization optimize 3 0.20 3 12 User-assisted trace True True Cover the area you want to select as the foreground then select both objects start True 0 13 4 False True Single scan False True start vertical True True start 8 8 4 4 4 True 0 Brightness steps Colors Grays Autotrace (slower) 0 1 4 True start Scans 0 2 True start Detection mode: 0 0 3 Smooth True True Apply Gaussian blur to the bitmap before tracing start True 0 4 Remove background True True Remove bottom (background) layer when done start True 0 5 3 True True The desired number of scans MS_scans 8 3 2 True start Details: 0 8 3 60 True True True speckles False 1 10 2 True True Speckles of up to this many pixels will be suppressed speckles 2 3 10 Speckles True True Ignore small spots (speckles) in the bitmap start True True 0 10 Optimize True True Try to optimize paths by joining adjacent Bezier curve segments start True True 0 12 True True True optimize False 1 12 2 True True Increase this to smooth corners more smooth 2 1 3 11 True True True smooth False 1 11 2 Smooth corners True True Smooth out sharp corners of the trace start True True 0 11 True True Increase this to reduce the number of nodes in the trace by more aggressive optimization optimize 3 0.20 3 12 User-assisted trace True True Cover the area you want to select as the foreground then select both objects start True 0 13 3 True True True MS_scans 1 False 1 2 2 Stack True True Stack scans on top of one another (no gaps) instead of tiling (usually with gaps) start True 1 4 3 False 1 True Multicolor 1 False True start vertical True start 8 8 4 4 4 2 True Favors connections that are part of a long curve (multiplier) start Curves 0 1 True Avoid single disconnected pixels (weight) start Islands 0 2 True Favors connections that are part of foreground color start 8 Sparse pixels: 0 3 2 True True The heuristic computed vote will be multiplied by this value PA_curves 3 True 1 2 1 True True A constant vote value PA_islands True 5 2 2 True True The radius of the window analyzed PA_sparse1 True 2 2 4 True True The heuristic computed vote will be multiplied by this value PA_sparse2 3 True 1 2 5 True start Heuristics: 0 0 2 60 True True True PA_curves 1 False 1 1 True True True PA_islands False 1 2 True True True PA_sparse1 False 1 4 True True True PA_sparse2 False 1 5 B-splines True True Preserve staircasing artifacts start True RB_PA_voronoi 0 9 2 Voronoi True True Output composed of straight lines start True True 0 8 2 True start Output: 0 7 2 Optimize True True Try to optimize paths by joining adjacent Bezier curve segments start True 0 6 2 True Favors connections that are part of foreground color start Multiplier 0 5 True Favors connections that are part of foreground color start Window radius 0 4 2 True start Pixel art 2 False True 4 4 True True True 5 5 5 5 True True vertical 100 100 True 4 True True Live updates True True True Update preview True True True center end 1 1 True 4 Preview: True 1 True True 4 5 5 True True False True Instructions 4 up popover1 True info-outline-symbolic True crossfade True True True 3 center Revert True True True Apply 150 True True True True 1 True 1 True True True Abort trace operation True off-outline-symbolic True center True 5 1 page0 1 True 2 1
