Grooves not setting - hendrikbez - 02-12-2022
I have a file in gimp.
Gimp file
I want to add Grooves to the image, but I cannot get it to set
When I move around I can see the groove moving, but when I click to add it, it does not.
What am I doing wrong.

Make a gradient with settings
1) FG to BG (Hardedge
2) Shape Radial
3) Repeat Sawtooth wave
Draw it from center, a tiny amount and it repeats as concentric circles.
Then a choice. Color to alpha and make one of the colors transparent or as this black/white and the layer mode (4) Darken only.

Thank you, But I need the Grooves in the outside, like a coin groove

Something like this ?

I used gear :
[attachment=7460]
Then I used Ottia Tuota plugin : tools / modify path / round corners
Then you can use : 'select / from path' to make a selection
Invert the selection : 'select / invert'
Set the layer with the purple disc active and delete the 'grooves'

RE: Grooves not setting - rich2005 - 02-12-2022
Best to start off with an image as denzjos shows, That is the shape-paths script, you can use a gear shape or a star shape.
However it is possible with a bit of selecting and cutting to make a serrated edge on your image.
This using the paint tool to paint around a selection, a spacing greater than 100% the paint too paints dots. Then it is using that as a template to cut the main image.

Thank you for the info, but where do you get all that shapes, I cannot find them in gimp.

Just one question, I do have a groove brush that I want to use, but when I click to add it to the layer groove it does not do it, why?
I did went true the pdf file, and done everting like they said, but the Grooves brush does not work at all.
It look like this

@hendrikbez, you can find the gimp script to make a 'gear' path here :
http://gimpchat.com/viewtopic.php?f=9&t=17044
Download 'shape-path-091.scm' and put it on your scripts folder
I used it with this values :

Thank you, got the script.
Will see how it works
RE: Grooves not setting - rich2005 - 02-13-2022
@denzjos, Come on, no need to go to gimpchat
that script here: https://www.gimp-forum.net/attachment.php?aid=2116 and of course should always mention Ofnuts plugin ofn-path-to-shape.py from http://sourceforge.net/projects/gimp-path-tools/files/scripts/ (ofn-path-to-shape.zip dated 2016-12-26)@hedrickbez Is that brush a full circle shape ? Without using it not easy to see what is going wrong. Sometimes a brush is used as a 'stamp' one-click to paint, sometimes a brush is used with the eraser tool to cut out a shape.
Another way is use a path, I will attach one I made It is sized for your 1000x1000 image but a path (a vector) scales up or down without loss of quality.
This one milled-edge.svg is not opened as an image, right click in the paths dock and use import path. Then Select > from Path, and in this case invert the selection and cut out the edge.
