You interface your scripting language via PDB calls in the
libgimp. Probably the easiest route to scripting is to implement wrappers
for gimp_main and gimp_call_procedure2 in rexx.

These two functions alone allow you to start a plug-in (and enter gimp_main)
and then subsequently call pdb functions. The trickiest thing is to write a
converter between GParam's and Rexx and vice versa.

Well, and some syntactic sugar would be nice as well ;)

After having done that you might choose to write some interface dialog
(like script-fu) or give the full power of Gtk to your script users (get a
Gtk+ interface for rexx).

Read the include files for libgimp and some example sources, like the
tcl plug-in (or python and perl, but these I think are more difficult to
read).

How to add other script language support ?

1999-11-20 Thread m . hessling 

I realise that this may be considered sacrilege; but I am interested in
adding the ability to write gimp scripts in Rexx.  I've spent about a
week looking for documentation on how to go about interfacing to gimp,
but have not come across any documentation explaining interfacing to
gimp via a C or C++ API.

I'm not clear on whether the interface would be done via Gtk, the PDB
or via some other interface.

Any pointers on what documentation is available and where it is would
be appreciated.

Cheers, Mark.
