I don't care how you do what you do.
As long as you keep on doing what it is you've been doing,
that you do so well. :puzzled

Yes "Than" is the correct spelling for that sentence.

This is why the English language is so confusing to learn. :lol

.
Peace and Piece
Than and Then
Too, and To
Their and There
Witch and Which
So and Sew (there is also Sow)
Shoe and Shew
The list seems endless. :gaah

This python filter is awesome Tran. Thank you very much.

Rel 2. works on selection bounding box/rectangle. (USE .py instead of .scm).

Attachment:

guides_to_path.scm

REMOVE .scm above,
Use the .py below it's more advanced (registered under same location)
Release 1.

Attachment:

guides_to_path.zip

.py features composing sections so that you can easily edit the path.
(as requested by mahvin)
(also defaulting the path to visible requested by Obinbc).
[ Image ]

Will be available under /Image/Guides/Guides to path
[ Image ]

If there is no selection all guides will turn into path.
If there is a selection, guides within the selection bounding (box/rectangle) will turn into path.

Hi, suggestion add an boolean to either stroke at once or not with brush and foreground
if ....
pdb.gimp_edit_stroke_vectors(image.layers[0],new_vectors)

works ;-)
greets

Stroking a path with a brush is never very clean. There is unfortunately no API to stroke a path in "line" mode, which looks a lot better. And adding the choice to a script is just replacing the use of Edit>Stroke path by the selection of the option.

They could just right click the Path they want stroked and vectorize it

I strongly agree... plus if i added the option to stroke path, it wouldn't be "Guides To Path" anymore which i think is a good function on its own right now.

My personal choice is that if the stroking of a path is needed as part of a process for a script, like stroke path then doing something else with it, then I'll look into making that work (previously I had to resort to some other hacks that i found online that uses .svg to stroke path). But in this case it's just a step that's added onto the end of an isolated function "Guides To Path" I don't see the point for it. I think it's better to let user do it themselves they have more options to play with anyways.

I like it just the way it is now.

Tranductim,
Looked up your guides-to-path script.

I realized that is creates order m * n vectors (so to say if n = m, its quadratic in time usage)

I used your script to make it order (m + n) , only total length vectors created ...
Measuring time shows indeed time advantage ...

Interested in the so to say 1.1 version of you and me?

Peter

EDIT: just discovered, small error in my script, if there is e.g. only one guide ;-(, to be repaired !

EDIT EDIT: Repaired :yes

How did you manage that,
does it still produce lines that meet at intersection points?
if so, yes i would be very interested.
