SplineEditor
ABU 31-dec-2021 (ver 1.0 released)
ABU 30-mar-2022 (ver 1.1 released) - with Undo/Redo
ABU 16-nov-2025 (ver 1.2 released) - new improved version
Everything started with a little experiment, trying to draw splines (Catmull-Rom Centripetal Splines), but then ... why not a full editor ?
Well, this is not a full professional editor, it's just the 1.0 milestone but I think it has enough features for creating interesting vectorial drawings.
SplineEditor v1.2
It's been almost three years since the last release of Spline Editor, and I realized it couldn't continue to remain incomplete and half-baked. So I decided to complete it; although it doesn't have all the features imaginable for a vector editor, many features have been added, including the most notable:
- Ability to rotate splines
- Ability to split/join splines
- Ability to scale spline thickness
- Ability to save only a portion of splines
- Facilities for fine-tuning movement using the arrow keys
- Tcl9 compatible.
As well as a long list of small bug fixes... -- I hope you find it as fun as I did tracing and adjusting simple drawings like those in comic strips.
Here you can download the full source ( it's 100% pure Tcl )
Jeff Smith 2022-03-31 : Below is an online demo using CloudTk. This demo runs "SplineEditor" in a Alpine Linux Docker Container. It is a 28.4MB image which is made up of Alpine Linux + tclkit + SplineEditor.kit + libx11 + libxft + fontconfig + ttf-linux-libertine. It is run under a user account in the Container. The Container is restrictive with permissions for "Other" removed for "execute" and "read" for certain directories.

Please Note : This demo has a run time of 5 minutes.
4-jan-2022 - Minor bugfixing in progress about the user-interaction
30-mar-2022 - Code cleaning and 90% refactored. Added Undo/Redo
ABU 5-apr-2022 Now, after introducing the undo/redo feature, SplineEditor is ready to grow .. Next planned features are:
- breaking / joining splines (under testing)
- groups (..hard, but it will be a big plus)
- stroke-thickness is currently fixed (it doesn't change when a spline is scaled or zoomed) .. it should be dynamically resized
- APE handle SVG format -- ABU: You can export your drawings as SVG. Importing SVG is not planned, nor feasible , since this Editor works with Splines, not with SVG primitives (Bezier curves).
