Hello, I'm trying to create a plugin that will move the selection as if it's 'displacing' pixels as it moves. More specifically, if moving one pixel to the right, it will take all the pixels just to the right of the selection and place them on the left side of the selection.
If I had a way to test if a certain pixel is inside the selection or not, I could hack something together. So far I haven't found a way to test pixels for whether they are selected or not.
What do you guys think?

Hello,
I am looking for any Gimp 3 python API documentation link.
For now, I am mainly searching on Google, wich most of the time, yeld Gimp 2 API results (outdated), or C API (nice but translating from C to python is a PITA, too many trials and errors).

Hello,
I am having an hard time writing my first plus-in in Python.
I wrote a simple "Hello World" plug-in.
It show up in the menus (so the do_create_procedure member function work as intended).
It show up in the python procedures browser (so the do_query_procedures member function work as intended).
But it does not produce anything in the errors window and that leave me completly clueless.
What did I do wrong ?
Here is the source code:
Code:
import sys
import gi
gi.require_version('Gimp', '3.0')
from gi.repository import Gimp
gi.require_version('GimpUi', '3.0')
from gi.repository import GimpUi
from gi.repository import GLib
class Plugin (Gimp.PlugIn):
def do_query_procedures(self):
return [ "fl-plug-in-Hello-World" ]
def do_set_i18n (self, name):
return False
def do_create_procedure(self, name):
procedure = Gimp.ImageProcedure.new(self, name,
Gimp.PDBProcType.PLUGIN,
self.run, None)
procedure.set_image_types("*")
procedure.set_menu_label("Hello World Python plug-in")
procedure.add_menu_path('<Image>/Filters/My Scripts/')
procedure.set_documentation("Hello World",
"Python 3 plug-in for GIMP 3.0",
name)
procedure.set_attribution("Fabrice", "Lambert", "2025")
return procedure
def run(self, procedure, run_mode, image, n_drawables, drawables, config, run_data):
Gimp.message("Hello world!")
# do what you want to do, then, in case of success, return:
return procedure.new_return_values(Gimp.PDBStatusType.SUCCESS, GLib.Error())
Gimp.main(Plugin.__gtype__, sys.argv)
