I've been attempting to call the autocrop plug-in from within a C plug-in, but to no avail. My syntax is:

GimpDrawable *drawable; ...
plug_in_autocrop(image, *drawable);

and the error I get from running gimptool --install-admin on my plug-in is

'undefined reference to plug-in autocrop'

The includes and libraries that gimptool echos when run are:

-I/usr/include/gtk-1.2 -I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/X11R6/include

-L/usr/lib -lgimpui -lgimp -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXi -lXext -lX11 -lm

Attempting to run the plug-in with the alternate syntax:

drawable->autocrop();

generates the error

'structure has no member named 'autocrop'

If I try to run it with gimp_run_procedure, I get a segmentation fault.

Any thoughts about what I might be doing wrong?

TIA, Cindy Huyser

Randomly guessing syntaxes most probably won't help you much. :-)

Not really a random guess, but using a _very_old documented syntax: http://www.goof.com/pcg/marc/pdb/plug_in_autocrop.html

Libgimp has only wrappers for most of the gimp internal functions. For Plugins you need to use the gimp_run_procedure call directly, in your case something like the following (untested!):

params = gimp_run_procedure ("plug_in_autocrop", &retvals, GIMP_PDB_INT32, 1, GIMP_PDB_IMAGE, image_id, GIMP_PDB_DRAWABLE, drawable_id, GIMP_PDB_END);

I hope this helps.

Bye, Simon
