Optional preprocessing: equal illumination, median denoise filter.Īutotrace needs a bi-level bitmap. The input image is converted to a graymap and histogram normalized with. Find an entry in the new Path -> Trace Bitmap dialog. Since Inkscape 1.0 the Autotrace library including the CenterlineTrace feature is integrated. On Ubuntu and derivatives, run sudo apt-get install python-pil to install.įinally, restart inkscape, and find CenterlineTrace in the Extensions -> Images menue. if you do not have pillow/pil installed, the extension will output an error message prompting you to install it.Install the autotrace DEB package version 0.40.0 or later from e.g.As of, MacOS Support is back, but highly experimental. Please report success in the github issues.open a command line shell to install the inkscape extension:.open a command line shell to install the python-PIL module:.Install autotrace MacOS.zip version 0.40.0 or later from e.g.Older version: autotrace binary from autotrace-win64-binaries github repo)Ĭopy the downloaded autotrace.exe to Inkscape's User extensions folder, that should also work.Make sure the installation path is C:\Program Files (x86)\AutoTrace - this application searches there. Install autotrace win64-setup.zip version 0.40.0 or later from e.g.Instructions for Inkscape 0.92.2 and higher:.copy the files centerline-trace.inx, centerline-trace.py to your Inkscape User extensions folder (see Edit > Preferences > System: System info: User extensions).download the zip file of inkscape-centerline-trace and unpack it.the extension requires the installation of autotrace and python-pil (see below).Install the extension (all operating systems)
In inkscape it shows up under Extensions -> Images -> Centerline Trace. See centerline-tracing.svg for an illustration of the idea. It uses 'autotrace -centerline' and an optimal threshold to vectorize a pixel image.
Inkscape 1.0.1 has the feature built-in under Path -> Trace Bitmap -> Centerline tracing (autotrace) It was developed and tested with inkscape-0.92.3 - It probably does not run with inkscape 1.0.1 and should not be needed. The builtin inkscape 'trace bitmap' can only trace edges, thus resulting in double lines for most basic use cases.ĭownload Source code and Debian/Ubuntu package A bitmap vectorizer that can trace along the centerline of a stroke.
