I looked at Path/Vectors Export and Import and it seems it only does absolute pixels loading when importing.
So I wrote this script to "Save" and "Load" Path with 3 extra loading methods on top of ABSOLUTE(pixels) mode
RELATIVE (percentage) -- this mode will scale based on image width and height
RELATIVE WIDTH KEEP ASPECT RATIO -- this mode will scale based on width keeping aspect ratio of original path when saved.
RELATIVE HEIGHT KEEP ASPECT RATIO -- like RELATIVE WIDTH KEEP ASPECT RATIO but based on HEIGHT
This should help instead of having to manually scale the path after importing.

Just like click vectors and choose Save... or Load... (You must have at least one path to access these menus, even if it's just an empty path)

more details. --> here

Tryed your script ;-)
Works, but only if there is at least ONE path (empty suffices) available.

Reason why is not yet clear to me ...

yeah i don't know how to solve that either.
When you load you shouldn't need an empty path (or at least one opened) but i don't know how to make it so that it doesn't need a path, I am guessing that's just how the menu items on <Vectors>/ menu register works but i am not too sure either.

Thank You for this plug-ins.

Only suggestions:

1. Change of location in the menu Gimp(very simple).

2. Adding options at load / save: select the filename and directory ?
(probably very difficult - perhaps impossible - creates the first empty paths.txt while loading the Gimp)

IMHO you script should work a bit differently:

1) let people export a standard SVG (no script needed)
2) work as an improved SVG import: load the path with pdb.gimp_vectors_import_from_file(image, filename, merge, scale) (which may have useful options already) and then apply the required transformations on the loaded path.

Benefits:
1) you don't have to deal with the export (or with the complexities of the SGV format)
2) your script also applies to SVG from non-Gimp sources

I meant it to be a hack with its own format just to be used in GIMP. Didn't think about other apps.
I looked at the .svg exported and trying to import that .svg well would require a lot more brain power than i have right now...

I don't know how to allow a filename to be selected and at the same time allow user to choose a path from that file because the list of names in the drop down is generated at run time.
Probably involves like some live update like the ability to preview the result almost i think not too sure but i am not good enough to have user select a filename and at the same populate the drop down list

Not at all, using pdb.gimp_vectors_import_from_file(image, filename, merge, scale) means that Gimp is going to handle all the SVG decoding. You give it a file on one end (from a PF_FILENAME parameter, can't be any easier) and get a gimp.Vectors object at the other end so to speak.

And you already know how to do the transforms.

What that easy?
Maybe i just need to add a script that calls this
pdb.gimp_vectors_import_from_file(image, filename, merge, scale)
and after user choose .svg filename
and choose a loading method
for choosing a loading method i need to know original image size that path was exported.
looked at the svg.
it's under "viewBox" is there gimp's methods to get that info.
or do I parse that myself?

Could be done by looking at the SVG file with the xml.eTree library... but why would you need the size of the original image?

Because that's how i can have load methods like RELATIVE (percentage), RELATIVE WIDTH KEEPING ASPECT RATIO and RELATIVE HEIGHT KEEPING ASPECT RATIO. I need the original image's dimensions in order to know how the path sits on the original image in order to apply the same percentage on to the current image (that it's being loaded on).

Quite simple actually:


As far as I can tell, xml.etree.ElementTree is part of the Python package distributed with the Windows Gimp version.

In some files, you'll find heigh/width specified as '150px' or '2.4in' or '1200pt' so you may have to be a bit cautious when converting the values. Some files also define a 'viewBox' attribute.

I did it using the viewBox attribute because i only want to deal with exported path by GIMP.

I like the way you think...

Shhh Graechan..
I'll update it soon

Okay just updated the download link to point to version 3 of script.
Which works on selection bounding box.
It's easy because this script i am calculating the path myself.

But I tried to also apply this to the Import SVG Path with load methods and it's tripping me out i kept getting weird bugs.... i don't know about that one..maybe save it for another day when i am not so tripped out by simple scaling math.
