Re: [Gimp-developer] How to call gimp_export_image() from Pythonplugin

This is a missing feature in the 2.8 release. New features are usually not added
in stable release cycle, which is the case of gimp 2.8  - and gimp-python is
bound to it.

If it was something without which one would die - but  the
functionality can be obtained by 5 lines
of code, as already answered in the first e-mail.

I will deal shortly  with the other bug reported here - regarding the
"parent" atribute of layers, which
is being retrieved as Layer, not LayerGroup.
I might add the "export" method to GIMP Image objects - but that is a
new feature , I am  not sure if it should be backported to 2.8 .

It is not a PDB function, but a libgimp (C) function. Since pygimp can do
gimpui stuff (also C functions), there is no conceptual reason why pygimp
shouldn't also handle gimpexport (which is where gimp_export_image lives).

I thought that in Python it was straightforward to access C functions? This
is simply a function that returns an integer, albeit one that uses the GIMP
UI - which pygimp already can initialise.

IS it available throught the PDB?
Most GIMP - Python functions are done via PDB, except pixel-region
manipulation stuff.
If it is not in the PDB, it is not availabl in GIMP 2.8 - the current
GIMP Python structure has to
special cases a lot of things to work aside from the PDB, and doing so
is not minor stuff
done inside a release cycle.

Making the 3-4 above calls are straightforward - I see no reason to
violate the principle of no new features inside a release to add this.
In GIMP 2.10, the export feature will also have to deal with precision
management, and besides this export function, a class of PDB calls
dealing with precision needs
to be added as well.

Joao, Ed,

so gimp_export_image() should be exported to Python though PDB (to all
plugins) or by writing custom export code as done for some functions
to export it only to Python?
