Thanks for the prompt reply=2E I went for the action=2E I would have prefer=
ed to do it non-interactive but digging into the colorspace stuff
is too much for now=2E

Betreff:=C2=A0Re: Python API questions
1=2E To open a file as a layer without triggering dialogs, you will need
to open the file, add a new paintlayer node to the document you want
to add the file to, and copy the pixel data from one to the other=2E
Here you will need to make sure that the source and result images are
the same colorspace=2E If you are okay with triggering dialogs use the
"import_layer_as_paint_layer" action(as noted in 3)=2E
2=2E Undo isn't implemented in python, there was never a proper design
for it conceived=2E Triggered actions will proly be added to the undo,
but for the rest it is better to clone the document=2E
3=2E Krita is not 100% python=2E Instead, what you can do is access
certain actions is to use application()=2Eaction("action_name") (you can
get all the action names with
https://api=2Ekde=2Eorg/extragear-api/graphics-apidocs/krita/libs/libkis/h=
tml/classKrita=2Ehtml#a5cf481b65e4c0971777ceb9330c8a8e9
), then from the QAction object that gives you, use action=2Etrigger()=2E
The krita4=2Exmlgui in your resource folder gives the exact layout of
your menus with the actions as an xml file, using these names too=2E
