It has been several years since the last release but I'm trying to bring Knotter back to life.

I've set up a new workflow for releasing packages, and now new versions will be packaged automatically.

If you are interested, you can download it from here: https://knotter.mattbas.org/Version/Dev ... t_Snapshot

For now it doesn't have significant new features compared to the latest release but at least I'm able to keep maintaining it.

I had looked at Knotter a long time ago but was not experienced enough with digital graphics to understand how to begin. If I can get the fog out of my brain, I will try this as I really like the designs!

You can also check out the tutorials. https://knotter.mattbas.org/Tutorial

That is good news, Matt. I too had a lot of fun with your program but since then, my PC went through several crashes and upgrades and I had lost Knotter and haven't re-installed it since. May try to soon if work lightens up for me a bit.

This is great news - thank you.

Hi Mattia.

I am very glad that You have returned to the development of the program.
The first question is about the size of the program:
My "old version" 0.9.6 is about 76 MB.
Development version 0.9.7 is 463 MB (more than six times larger ).
Are you planning some "weight loss"?

I think it's due to libraries, for the Windows package I used to build it with mxe which linked libraries statically but it ended up having some issues, now I build it with MSYS2 but it means I need to ship the dlls as well.
I'm currently adding all the dlls in the environment because I'm not sure how I can tell which ones are needed and which aren't

It's a thankless task - but it helps a little:

Certainly built with mingw will take up less space (although this is not a problem for new very large drives - a bit worse with the pendrive version).
What are your further development plans?

Probably just general maintenance for now, fixing bugs and doing things based on feedback.

How about some code that does not give this error when compiling in linux



..and while the snap version works, an appimage would be of more appeal.

It compiles fine for me, maybe open an issue on gitlab with more details. https://gitlab.com/mattbas/Knotter/-/issues/

Thanks for reviving Knotter; think I had it linked in to GIMP before, but will now have to re-learn it. However, had a quick play, imported the result and used it as a pattern for a 'metallic' mandala. Thanks again.

Will knotter run on a macbook?

Yeah but at the moment I can't provide a package for mac because setting up an automatic build for it is difficult without having to pay for it

Any linux users up for a trial ?

knotter 0.97 compiled in 'buntu 18.04 / qt5
https://u.pcloud.link/publink/show?code ... LbmQ1gMr4y
about 20 MB zipped

unzip and....

It is qt5 and even if you have qt5 installed (say for gmic-gimp plugin) almost certainly some dependencies missing. In a fairly clean Mint 20 these required. There could well be more.



As a first try unzip knotter-097-linux-64 and run knotter in a terminal. See what transpires.

screenshot Mint 20 - I do not know what it is, but certainly a knot



Usual guarantee, there is none.

Added an AppImage download too

ive used and refined knotter plugins, specifically to make multiple circular patterns on demand. using Win 10 graphic windows ( just like knotter already uses win 10 user interface windows. ) i use Visual Studio Code to create the files needed... and it means one must change the variables and java script - it works really well. here is a window shot.. fully functional for the circle creator. it took me a while to figure out how to change variables in knotter... and the final problem ve found - is i cant access them all i want to pursue a an interactive single line generator like MS Paint can do with straight and curved lines ive had partial success, i can add points to double lines that are so close together they look like single line, then drag around the multiple point line and reshape ir on demand... but its just a hash attempt so far.. i can make a short gif i guess showing that working.. in a later post.. if folks are interested in the circle plugin and what it can do since ive made one to change and make multiple stars on demand too.. i can share the files... or even post them here as visual studio code....

nice ^^

mbasagli. would you like the changed java and windows interface files? for circle and star? i could do more, but trying to remove the integral line cusp so i can just use lines that dont end in a loop. is beating me, because i dont know what variables to look at.. if i remove this line... i can do it.. but its a hash fix..

this is what i did to stop the cusp -

make them out of circuit.

like this example : //path.add_line(cusp_point,in_line1.p2);

save the file. and if you know how rename it, and all the files that go with it... for example

open_knot_cusp etc etc

as of 16th december 2019 thats enough to make the script ignore the cusp making.. and so one will just get an open
knot when its used... that is, the knot lines will not close at the end the open_knot_cusp is used.

2. to set up for single line drawing, put 4 nodes on the screen, it doesnt matter if one is using a grid or
not, in fact the action is more fluid without the grid unless one is working at pixel level.

3. link the 4 nodes with the wall knot.

4, select all and make the gap in selected edges 0.01 not 0 but 0.01. the curve is best not more than 36 but it can be more or less

5. click on a node to select its properties, and choose the open_knot_cusp do that for all four nodes..

ones should now have a line connected by 4 nodes that one can move around fluidly by dragging the nodes,

6. its not a perfect solution, because the the links drag outside of the line and so do the nodes, but
one can extend the line and bend it , the more nodes one has in the line the better, but it can get
confusing in dense knots..
