Inkscape

Hooray! My favorite Inkscape extension is back! Many, many thanks to DrWiggly for all the work it took to revive this treasure! To download, click on the graphic.

Thanks for the port, haven't tried the old version. But when I try to follow the SinContourOnCircle example I get the following error:

Traceback (most recent call last):
File "guilloche_pattern.py", line 30, in <module>
from inkex import paths
ImportError: cannot import name paths

xR2, Sorry you're having trouble.

The error message you are getting is from the very beginning of the guilloche_pattern.py code. It is trying to import features from the core part of Inkscape. Those features are used later in the extension, but when the extension fails in any core execution I can't help you since I know nothing about the core code. Here are a few things you might try to narrow down the possible problems.

As I understand it, you opened file ...\PatternTests\SineWaveCircleWithCircle\SinContourOnCircleAndCircleInput.svg, and attempted to run the extension guilloche_pattern, and got the error message. Is this a correct description of the sequence of actions that fails for you?

If not, please try the above test. I can complete this sequence of actions successfully on versions v1.1 and v1.2.2.

I run Inkscape on Window 10. What is your operating system? Good luck.

There are many XML errors in the current ZIP file:

parser error : Opening and ending tag mismatch: option line … and _option

The solution is simple: just search-and-replace "_option" into "option" on both `*.inx` files.

While you're doing that, you can also change the submenu name from "Examples" to something more meaningful.

Hello DrWiggly, I have your Guilloche 1.1 extension working well on InkScape 1.1.2 (Ubuntu 22.04). I am a historian working on 19th century documents and wrote a python3 script to emulate a Kampf Geometric Lathe commonly used to ornament them. I have some maths for you that will add to your extension in a way that looks more like the engravings typical of the period. I don't know how to attach code or images here. Please let me know if you are interested in exchanging some insights. I can send the script and its user manual at your request.
