sorry, Rod, not to offer my help, but whenever the word "path" comes into the game I fly away:
paths "non sono nelle mie corde" as we say in Italy...
(maybe you say "I'm not in my comfort zone with paths", if Google translates correctly the Italian motto)

Check here for latest version -> Guides to Path (scheme script)
Here it is. Will be available under Image/Guides/Guide to path


Create your guides however you like, run script and a path will be created at which point you can use to stroke however you like.

To stroke just a selection, just make your selection then stroke the created path and it'll only stroke where the selection is present..that is already built-in.

If you wanted to select from guides just uncheck snap to grid and check snap to guides under /View/ and it's easy to select (rectangle select) from guides.

Wow, Tran! Did you write that script that fast?

well it's not very complex once you know which methods to call.

Great script! There is just one small nuisance for me:

I tried to enter intersecting path points on each row and column so that I could essentially cut the paths out where I didn't want them stroked, and it keeps cutting the whole path. Going to revisit the Path manual and see what I am doing wrong.

i think it's much faster if you choose snap to guides and then rectangle select the area you want stroked and then stroke it using the whole path.

i could never remember how to insert a point to delete other parts of the path either... i always mess aroudn with it for like tens of minutes before figuring it out and then instantly forget again.

EDIT: This spawns another idea...which is if there is selection (defined by a bounding box).... only draw paths within this bounding box.
So that you can rectangle select the first row, then it'll only draw paths within this rectangle then you can move on to the second row by rectangle selecting it and redefine the guides and then run script to create path for the 2nd row and so on.

Just added release 2 which will only create path within bounding box of selection (if there is a selection).

as it's own thread.
Guides to Path (scheme script)

Please have a look.

Sure

Am on the way


There is a new button: Your whish! ..

And your real wish is not yet 100% explained!
That 'must' be mathematically precise! Example you could wish to select TRIANGLES ?
Look into Error Console after L322 there is the info hidden about what
guides I had in the picture ...

You lost me here, sorry.
So what does the "Your Wish. Let Us Go" button do?

It does not do anything yet, because I need to know WHAT you exactly wish tod do!

E.g. two (or three??) horizontal guides two (or more) vertical guides and then select all rectangles inbetween(??? or ???) and select them and what next? stroke them black? or ???

So the wish is for a mathematician totally undecided ... exact wish is needed

EDIT:
Because my way lets the guide-lab live one could say: select and stroke always the first upper middel rectangle ... deleting is easy so other rectangles could become the most upper left rectangle to stroke.
But maybe you would like to stroke (with what) all only the upper ones etc

Hope it is now clear what I want to know

I got ya! Actually I want to stroke all the guides at once. Tran wrote one in scheme (script-fu) already but a Python filter would be handy also.

Now exists in python but a little more advanced.
It composes the path out of shorter line segments that meet at intersections so that you can easily edit/delete line sections from created path.

Now in Python (Guides to path).

Tin, you are AWESOME!

LOL! Is anybody polishing up Tin's Golden Wilbur?

An interesting idea, which I couldn’t get out of my mind wondering if it could be done. I got the selection from guides working then gave up on it, as I agree with ofnuts that it’s a roundabout way of doing things. I’ve uploaded the script here for anyone curious

Located at <Image>/Script-Fu/Guides to selection

It is an unfinished script with no error checking and will crash or can give odd results if the user doesn’t

Add 4 guides, must be 2 vertical and 2 horizontal (the order of placement doesn’t matter)

Run the script

Repeat x number of times

Path to selection
Stroke path

PS You may need to Re-start gimp and have only one image open before using

I created this SVG Gradient for GIMP using my Notepad ++ editor. I named it (SVG Blinds)



1) install the gradient attached into your gradient folder.

2) Open a new image and refresh your gradients
3) In the gradients dialog, select SVG Blinds from the list.
4) In tool options select conical (sym) for shape and NONE for repeat.
5) Drag the gradient from center of image layer to an outer corner.

Excellent script also! Thanks.

Just pulled this out of my archive (for various purposes) and as well as working in Gimp 2.10 it also works without modification in Gimp 3.0

Slight difference from previous attachment, some changes by MrQ so attached again.
