Imagetracer.js for Inkscape
Mario Voigt
This extension is an InkScape wrapper for https://github.com/jankovicsandras/imagetracerjs. It utilized a standalone node.js executable to run the JavaScript code. It will be fed with embedded or linked images within InkScape. The big difference between this tracer and all other tracers in recent InkScape is the fact that it is capable of splitting an image into it's "isles". The regular tracers separate by colors but not by objects. That makes it hard to work with sometimes. Imagetracer.js will vectorize your beautiful image into a more beautiful SVG trace with separated infills (break apart into single surfaces like a puzzle), that means you get a lot of single areas. works for Linux and Windows Docs: https://y.stadtfabrikanten.org/imagetracerjs

Styles To Layers
Mario Voigt
This extension will re-layer your selected items or the whole document according to their color (stroke or fill). Each style will be put onto it's own layer. This way you can devide elements by their colors with ease. It does some basic-only handling of gradient styles. Docs: https://y.stadtfabrikanten.org/stylestolayers See also https://inkscape.org/~MarioVoigt/%E2%98%85remove-empty-groups for useful cleaning extension. Notes: - includes "Apply Transformations" extension

Contour Scanner And Trimmer
Mario Voigt
Find open, closed and self-intersecting contours. Self-intersecting contours can be closed or open contours so you can select this option additionally! Docs: https://y.stadtfabrikanten.org/contourscannerandtrimmer TL;DR: Bentley-Ottmann algorithm is used to check for those intersections. The algorithm works with the accuracy of the selected paths (epsilons). Self-intersections usually happen if you just have large overlaps where the contour crosses itself like an 'eight' character for example. Using the highlighting it's easy to find contours with unproper path handles. While in a CAD system an area of of a surface can only be calculated if the contour is closed and clean, finding self intersections in Inkscape is not required to do so. SVG format allows to calculate areas on open contours and self-twisted curves. This "artwork behaviour" makes it harder for handling machinery-like drawings for laser cutting, vinyl cutting or whatever. That's why we need to have extra sanity checks but we also have the great freedom of Inkscape. Finding self-intersecting contours does only work for curves with straight line segments (polylines) because it just calculates with a set of given XY points. It does not respect bezier curve segments. Bezier curves have no regular points but special handles, which define the slope of the curve per handle side (left and right). To properly handle a bezier curve we need to split the bezier curve in a lot of small linear segments (acting like infinitessimal solution). We can use the tool "Flatten Bezier to do this (will make your curve looking edgy or ugly possible). If you want to leave the shape of the line clean (bezier type, no edgy approximation) we can use Split Bezier (Subdivide) or Add Nodes instead. But remember that your calculated self-intersection points will only be an approximation then. The higher the subdivide count is the higher the precision of the calculated self-intersecting points coordinates will be.

WebP Import
Mario Voigt
Import *.webp image files using ImageMagick conversion. Routine is webp → png → svg → write into Inkscape canvas. You need to install ImageMagick. The command "magick" or "convert" needs to be in path variable, otherwise the extension will fail. Docs: https://y.stadtfabrikanten.org/webp-import

Slic3r STL Input
Mario Voigt
STL Sliced Import (by Slic3r). Supports OBJ/OFF/PLY/STL as input file formats. How it works: - projects an STL file on the X-Y plane by cutting the objects into "slices" - each "slice" is a group of polygons, with a label indicating its z position - the polygons are converted to paths for better editing in inkscape - use Object → Rows & Columns → distribute the slices in a grid Warning: Requires Slicer 1.3.1-dev (the really latest build possible) docs: https://y.stadtfabrikanten.org/slic3rstlinput based on stl input extension of Jürgen Weigert. Thanks for your hard work.

Ids to text elements
whidev
A simple Inkscape extension that lets you extract attributes (like id) from all selected paths, and show them as <text> elements inside the paths. Useful for when you want to have all paths' id shown on the SVG document as <text> nodes. You can also use it for other path attributes, like `label`, `fill`, `stroke`, `width`, `height`. Available under the Extensions > Text submenu. Check the extension's repo on GitHub for examples. Options for styling and formatting the text: Font size in pixels Color (the fill color of the <text> elements) Font (should be installed on the system) Font Weight (should be supported by the selected font) Angle (controls the rotation of the generated <text> elements, in degrees) Options for further editing the extracted text (only used with id and label attributes): Text to replace (a simple replace function to remove characters you may not want from the text) Match Regular Expression (matches the extracted text of each path to a regular expression and uses the result on the path, e.g. if the id is `Province_055` and this field `\d+`, the text on the path will be just `055`) Capitalize (capitalize all text) Group paths with the generated text elements (if checked, also group the path with its text label) Note: only works on <path> elements. If you have a <circle>, <rectangle>, <text>, etc., first use Object > Object to Path to convert it. For Inkscape v0.92 and before, you should check the extension's repository on GitHub.

Paperfold
Mario Voigt
Paperfold is another flattener for triangle mesh files, heavily based on https://github.com/felixfeliz/paperfoldmodels by Felix Scholz aka felixfeliz. Possible input files are STL, Wavefront OBJ, PLY and OFF. To run this you need to install OpenMesh with python pip. The algorithm of paperfoldmodels consists of three steps: - Find a minimum spanning tree of the dual graph of the mesh. - Unfold the dual graph. - Remove self-intersections by adding additional cuts along edges. Reference: The code is mostly based on the algorithm presented in a by Straub and Prautzsch (https://geom.ivd.kit.edu/downloads/proj-paper-models_cut_out_sheets.pdf).

vpypetools - vpype for Inkscape
Mario Voigt
vpype is a command processor working with SVG files. It can do a lot of productive steps to optimize files for different purposes like pen plotting, laser cutting or the generation of creative artwork. vpype is really powerful and helps to extend Inkscape feature capability. vpype contains a lot of functionality which is included natively within Inkscape. The extension "vpype for Inkscape" does not deal with all features but with a set of important commands like linemerge, linesort, linesimplify, occult, etc. We can use it to shorten tool path lengths, remove hiddenlines and so on. vpype converts all elements into simple SVG elements like svg:line, svg:polyline and svg:polygon. They can be displayed properly in Inkscape, but they have no knot handles to edit (see https://alpha.inkscape.org/vectors/www.inkscapeforum.com/viewtopicb51d.html?f=16&t=32562). We need to convert those elements to svg:path using key combination CTRL + SHIFT + C ("object to path"; do not use "stroke to path" because it will duplicate your outline with inset and outset contours). Our extension allows to do this conversion automatically. Documentation: https://y.stadtfabrikanten.org/vpypetools

Convert To Polylines
Mario Voigt
This extension takes the points of a path and make a straight polyline out of it. Nothing less, nothing more. You can do the same with default Inkscape UI (select the path -> Node Tool -> Straighten lines) but it might be quicker to use in some use cases. This extension handles duplicate points on a path by removing them. Docs: https://y.stadtfabrikanten.org/convert-to-polylines

Unwind Paths
Mario Voigt
An extension to wrap off paths to receive horizontal lines or extruded bands. Can be used for paper crafting, analysis and other works. You can also just use it to colorize path segments. Docs: https://y.stadtfabrikanten.org/unwindpaths Note: Unwind Paths is similar to https://inkscape.org/~Shoshanaz/%E2%98%85horizontal-lines-effect-hlines, but it is more andvanced as it supports bezier curves and allows to create extruded bands, style config, etc.

Ungrouper And Element Migrator/Filter
Mario Voigt
This extension parses the selection and will put all elements into one single group. If you have a cluster with lots of groups and elements you will clean up this way (one top level group, all elements below it). If you select a single element or a set of elements you just wrap it like using CTRL + G (like making a usual group). You can also use this extension to filter out unwanted SVG elements at all. This tool is also able to drop elements with certain SVG tags to perform some kind of cleanup in the selection. You can drop elements like circle,ellipse,image,line,path,polyline,rect,text,tspan and some more. Notes: - includes "Remove Empty Groups" extension - includes "Apply Transformations" extension Docs: https://y.stadtfabrikanten.org/migrategroups

Create Links (Breakaway Connectors)
Mario Voigt
To create tabs in Inkscape, we cannot properly use the integrated eraser tool. It will clip only in a cosmetic fashion but we do not get the real paths we need. Creating links (also known as microtabs, tabs, bridges, breakaway connectors, links, perforations) is sometimes required for laser cutting or vinyl cutting. This extension allows to pinch paths to create according segments - no cosmetic one's, but real segments. It will split up open or closed contours with user defined rules. To get best output please try to close open paths before using. Docs: https://y.stadtfabrikanten.org/createlinks

Typst
jcwinkler
Typst is a markdown-based typesetting system comparable to LaTeX but much easier to learn. This extension renders typst code to svg and inserts it into your Inkscape document. Notes: - This extension will be part of Inkscape by default, most likely starting with Inkscape 1.4. Until then you need to install it as described below. - This extension just inserts a formula into your document. If you need to edit your formulas try the TexText extension, which also supports typst: https://github.com/textext/textext Installation instructions (2 possibilities): A) Installation via Inkscape's Extension Manager 1. Download the zip file 2. Launch Inkscape and open "Extensions" - "Manage Extensions..." 3. Select "Install Packages" and then click on the disk button 4. Select the downloaded zip file and close the extension manager. 5. Restart Inkscape. You will find the extension under "Extensions"- "Text" - "Typst Formula..." B) Manual installation 1. Download the zip file 2. Extract its content into Linux, Mac: ~/.config/inkscape/extensions Windows: C:\Users\AppData\Roaming\inkscape\extensions 3. Restart Inkscape. You will find the extension under "Extensions"- "Text" - "Typst Formula..."

Export to LaserGRBL for laser cutting
Nikki.Smith
This free extension for Inkscape speeds up preparation of laser cutting jobs by exporting Gcode to LaserGRBL (included with most laser cutters). Pick your model of laser and material / thickness from pulldown lists, then export a complex job directly into LaserGRBL with one click. Use different coloured lines for each part of a job. eg, red lines to engrave in a single pass at 3000 mm/min @ 80% power, but blue lines cut in 3 passes at 300 mm/min @ 90% power. The emphasis is on it being very easy to use, with the bare minimum of settings. v1.21 17/Dec/2024

Cleanup Styles
Mario Voigt
This plugin is a bit similar to [Blueprint Maker](https://y.stadtfabrikanten.org/blueprint-maker) but has a more special use case and a lot of options! It is useful for adjusting the stroke width and opacity of large groups. Usually for good laser cutting the line width has to match a maximum width to be recognized as a hairline. Additionally often opacity issues cause that lines are missed by laser cutter. Docs: https://y.stadtfabrikanten.org/cleanup-styles

Localization / translation example extension
Nikki.Smith
For extension developers. This minimal extension pulls together some helpful documentation about adding localization to an extension, including where the translation files go and what gettext commands to use on both Windows and Linux. Now includes localized text in the Python script. Also many small changes that result in a much higher pylint code score.

Dynamic GUI example extensions with GTK
Nikki.Smith
For extension developers. Most extensions to Inkscape use an .inx file that describes a static user interface, then a Python script is run one time when the user clicks "Apply". To create a dynamic UI (that changes as the user clicks buttons, selects from dropdown menus, etc) you can build it in GTK using a Python script that runs immediately. Requires Inkscape v1.1 or newer. These short examples demonstrate a handful of functions in GTK+ 3. Now includes an example extension that uses a .glade XML file to create the UI with Gtk.Builder(). Also many small changes that result in much higher pylint code scores.

xkcdify
Gui Meira
This extension modifies your paths to make them look hand-drawn like the ones in xkcd comics (https://xkcd.com/). It does so by first adding more nodes to your path and then adding a little bit of noise to the position of each node. The algorithm was adapted from the one used in matplotlib's xkcd function: https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.xkcd.html The extension can also replace the fonts of all the selected texts with Humor Sans, which looks (kinda) similar to the text on xkcd. Installation: 1) Download the zip file for this extension. 2) Open Inkscape and go to Edit > Preferences. Open the System tab on the left panel. You'll see a list of folder names. 3) Locate the User extensions folder and click Open. 4) Extract the files from the xkcdify release you just downloaded into this folder and restart Inkscape. 5) Optionally, download and install the Humor Sans font. It can be obtained here: https://github.com/shreyankg/xkcd-desktop/blob/master/Humor-Sans.ttf Usage: 1) Select the paths and texts you want to xkcdify 2) Go to Extensions > Modify paths > xkcdify 3) Adjust the parameters to tune the effect to your liking. You can enable the live preview using the checkbox at the bottom of the window This extension only processes paths. If you want to xkcdify ellipses, rectangles, and other shapes, convert them to paths first using Path > Object to path This project is not affiliated, authorized, or endorsed by xkcd. I'm just a guy on the internet who thinks xkcd is cool.

Sibelius ViewBox
musikai
This is an extension for Inkscape 1.2 for correcting SVG-files that were exported by Sibelius via the graphic selection tool. These SVG are always the full page with 4 white rectangles that cover the unwanted area. The page size and viewbox isn't set correctly to show only the selected area. The extension will correct this and has the options to - remove the white cover boxes - remove all elements that are outside the page (most of it). #### Download: Click on the image above #### Video: https://www.youtube.com/watch?v=Jg7QqarVrA4 #### Installation: On Windows extract the zip file into something like this path: C:\Users\yourname\AppData\Roaming\inkscape\extensions\ To find and open the correct folder you can also open Inkscape->Edit->Preferences->System->User Extensions->Open After installation and restart Inkscape you can run the extension in "Extensions"->Document->Sibelius Viewbox. #### (Optional) Usage as .bat-file to process multiple SVGs: As it is a python script it also can be used to batch process multiple files via command line. Put this line into a text-file, edit the paths (yourname) and save as SibeliusViewbox.bat: for %%a in (%*) do python.exe "C:\Users\yourname\AppData\Roaming\inkscape\extensions\SibeliusViewbox\SibeliusViewboxExtension.py" --remove_whiteboxes=True --remove_elements=True %%a > %%a_viewbox.svg An example .bat-file is included. Once created you can drag and drop multiple SVGs onto the SibeliusViewbox.bat-file and the script will generate the corrected SVGs. Note: If Inkscape is not installed in "C:\Program Files\" you must edit the Python script. #### (Optional) Add .bat-file to Send-to-Menu: You can add the .bat-file to the Windows Send-to-menu. Open Windows-Explorer and insert this into the address-bar: shell:sendto This opens the Send-to-folder. Copy the .bat-file into it. Now you can select all your SVGs, right click -> Send-to -> SibeliusViewbox.bat
