Removeduplicatenodes
Ellen Wasbø
Remove duplicate nodes from path and join nodes closer than a specified distance. Optionally close paths if start/end nodes are closer than a specified distance. When joining nodes the new coordinate will be interpolated from the original coordinates. If separate paths are combined (Ctrl+K) these can be joined if closer than a specified distance. This join can be either a straight line or an interpolation. The extension will appear in Extensions -> Cutlings

Inkscape Axonometric Projections 4.0
Jeroen Hoek
This Inkscape extension transforms objects drawn on a two-dimensional plane to an isometric projection — or even any other dimetric or trimetric projection. Inkscape provides an axonometric grid that by default is configured for the isometric projection (i.e., the three axes are set at 120° angles). Drawing with this grid works quite well for simple shapes, but sometimes it is easier to draw the details of an object using a two-dimensional grid, and then scale, shear, and rotate the object to set it on an isometric plane. For more information, see: https://github.com/jdhoek/inkscape-isometric-projection For users of Inkscape versions older than 1.0-beta2, please use version 1.2 of this extension: https://github.com/jdhoek/inkscape-isometric-projection/releases/tag/v1.2 If you find a bug, please report it here: https://github.com/jdhoek/inkscape-isometric-projection/issues

Rounded Corners
crowhoot
Rounded Corners Version 1.3 by Chris Hawley This effect is designed to round off the corners on shapes made with the pencil tool. It will round off corners made of straight edges, while ignoring bezier lines. Corners that are too short for the desired radius will also be ignored. It does not work on Inkscape objects like the rectangle or star - the user must convert objects to paths before using this extension. Installation and usage instructions are at https://github.com/hawley577/Inkscape-Rounded-Corners/wiki Download the latest version on github: https://github.com/hawley577/Inkscape-Rounded-Corners

Multiple Boolean Operations with Inx Pathops
Maren Hachmann
Boolean operations for multiple objects at once - difference, union, intersection, exclusion, division or cut. The extension is a rewrite of the Multi-Bool extension, and offers many adjustable settings and improvements. It takes a selection of one or more groups, or of several elements (paths, shapes, text), or a mix of both, and applies a chosen path operation with the top-most valid object in paint order and each other valid object which is part of the selection (directly or as member of a processed group) that is lower in Z-order. For more info, please refer to the README file at https://gitlab.com/moini_ink/inx-pathops/-/blob/master/README.md . Inkscape extension written by su-v and updated for Inkscape 1.0 – 1.4 by Maren Hachmann, licensed GPLv2 or higher.

Line Animator (draw by invisible hand)
Maren Hachmann
Create simple, line-drawing animations for the web from selected paths. When you look at the file that you've applied the extension to using a web browser, it will look as if someone were drawing the paths with an invisible pen. Notes: * Find the extension as `Extensions > Animation > Line Animator` * **Only path objects** can be used for this. * **No path effects** should be applied to the paths (something may happen, but perhaps not what you expect). * The paths must have **a visible stroke** (else you won't see anything happen). * The object **lowest in stacking order** will be drawn **first**, then the one above it etc. * Animation speed can be changed by using the same animation name and selecting the same objects, then setting a different duration. * If you are animating a path consisting of **multiple subpaths**, all of them will start to be animated **at the same time**, but the shorter ones will finish first. * If you want to **change the direction** in which a path is drawn, change the path direction in Inkscape (`Path > Reverse`). Examples -------- See https://gitlab.com/Moini/ink_line_animator/-/blob/master/README.md Installation ------------ Drop the files `line-animator.py` and `line-animator.inx` into your user extensions directory. Learn where to find the directory in Inkscape: `Edit > Preferences > System > User extensions`. License ------- This software is licensed under the GPL v2.0 or higher. Note ---- Due to a bug in Inkscape (https://gitlab.com/inkscape/inbox/-/issues/9327), Inkscape 1.3 instantly crashes when you open the Selectors and CSS dialog. So don't do that!

RealScale (resize by line of known length)
Maren Hachmann
Quickly resize (architectural) drawings by indicating a line and its length in real world units. Optionally scale the drawing with a specific scale factor and draw a scale rule. Version 1.2, Inkscape extension for Inkscape 1.2 and higher. Download most current version from here: https://gitlab.com/Moini/inkscape-realscale-extension/-/archive/master/inkscape-realscale-extension-master.zip Installation: Copy the files realscale.py and realscale.inx into the directory indicated in Edit -> Preferences -> System: User extensions Usage: • Import an architectural drawing / floor plan / map /... into Inkscape or open a file containing one. Make sure it is a single object (group it, if necessary). • Draw a straight line that connects two points in that drawing of which you know the distance in real life (for example, if you know how long a wall of your house in the drawing is, draw the line from one end of the wall to the other). • Select the line, then add the drawing to the selection. • Open the extension dialog: Extensions -> Scaling -> RealScale... • Enter the length of the line you just drew, as it is in the real world (for example, if your house wall is 10.5 m long, enter 10.50. • Select the unit you used (for your 10.50 m house, select m; for your 10 cm cardboard box, select cm) • If you intend to print the drawing, and the original object is bigger than the sheet, consider using a scale factor. • To do so, first select if you want to use a metric scale factor (based on mulitples of 5) or an imperial one (based on multiples of 2) or if you would like to enter your own scale factor. • Then, in the corresponding dropdown, or in the number entry field, select or enter the scale you would like to use. The dropdowns only offer scale factors for downscaling. In the 'Custom' field, however, you can also enter values smaller than 1 to upscale a drawing. • If you would like the scale rule to be drawn on the page, check the option 'Generate Scale Rule'. • Now choose the number of units the scale rule will comprise. Those will be doubled in the generated scale rule - e.g. it will show 10 cm to the left of the scale rule center (labelled 0) and 10 cm to its right. • Apply!

Contour Scanner And Trimmer
Mario Voigt
This tool helps you to find nasty contours which might bug you and prevent your work from being ready for production. It will find open contours, closed contours and self-intersecting contours. Self-intersecting contours can be closed or open contours so you can select this option additionally! 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.

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.

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://stadtfabrikanten.org/display/IFM/vpypetools

lirror
tgk
Inkscape extension for creating generative art. The scope of this extension has been kept very minimal. It simply takes the selected object(s) and creates the specified number of copies of it. Each new copy will have a cumulative transformation applied to it where each transformation consists of - a rotation around 0,0 (top left of the canvas), - a shift in x and y, and - a scale operation in x and y. The rotation and shift operation can be done either lineraly (the same amount for every copy) or by a sinusidal factor (oscillating for each copy). The source is available at https://github.com/tgk/lirror

Round Corners
Jürgen Weigert
Apply a radius to sharp corners of a path. The extension is written for inkscape 1.0.1 (but also contains a backport for 0.92.4). Usage: The screenshot demonstrates the usage. In the upper half, a red path with 4 vertices is shown. We select two vertices: the top left and bottom left corner (shown in blue). Run "Rounded Corners" from "Extensions" -> "Modify Path". The result is the path below. (Viewed here in edit mode again to show all the new vertices.)

path animation
katkitty
Create svg path animation from frames. A path can be animated as follows: <path d="{orignal frame}"> <animate attributeName="d" attributeType="XML" begin="0s" dur="0.73" repeatCount="2" values="{frame1};{frame2}[;{framen}]"> </path> Most browsers will draw the path, then animate it, interpolating between the paths in the animate values list. Some i-phone browsers do not animate. Grrr. To use: Place each frame of the animation in a layer named 'frame{n}'. Each of these layers should have the same number of paths, and each path should have the same number of points as the corresponding path in other layers. The animation is applied to the paths in the first layer in the sequence, so the properties of that layer are used. Animations with different numbers of frames can be put into different sequences, named 'sequence{n}', using sub-groups: Layers: > not_animated_layer1 > sequence1 >> frame1 >>> path1a >>> path2a >> frame5 >>> path1b >>> path2b >> frame2 >>> path1c >>> path2c >> frame4 >>> path1d >>> path2d > sequence5 >> frame >> frame >> frame NOTE, any numbers on frames or sequence are ignored. The z order of frames and paths determine their position in the animation. SUGGESTION: Set all frames but the first to not display or even delete them before using the animated SVG in a browser. Experiment with different duration times for each path. NOTE: The pop-up box does not close after creating the animate node. The node appears under the paths in the first frame of each sequence. NOTE: Inkscape does NOT run the animation! You need to load the svg into a web browser to see it.

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://stadtfabrikanten.org/pages/viewpage.action?pageId=104923235

Openclosedpath
Ellen Wasbø
This extension will open up closed paths by removing all z-commands from the selected paths. My purpose: to use single line svg-fonts as otf/ttf/opf fonts. These font formats require closed paths and will add a closing command to the glyphs. This closing can be removed by converting the text to paths, ungroup and then using this extension.

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

Exponential X-Axis
Jürgen Weigert
This Inkscape extension transforms an object along the x-axis. The bounding box remains unchanged. Points near the center of the object move to create the illusion of a curved surface. Points move left, if you choose an exponent > 1, and right if the exponent is < 1. An exponent of 1.0 does exactly nothing. This can be used in combination with the bend path effect to create a cone projection that retains aspect ratio. Idea from Simon Budig while preparing for the lampshade workshop.

Paths to Lines
Scott Pakin
Paths to Lines converts a path to a sequence of lines, represented internally using your choice of SVG <line>, <polyline>, or <path> elements. It is similar to the Flatten Beziers, Straighten Segments, and Convert to Polylines extensions, but those always leave the path as an SVG <path> while Paths to Lines offers the user a choice among multiple SVG representations.
