The problem is the "gimp_drawable_get".  As you can learn in the
"GimpDrawable" section of the libgimp documentation, this function
does not return the integer ID of the drawable, it creatss a
new struct containing information about the drawable.  I think
you should just use param[2].data.d_drawable.  (The handling of
drawables in libgimp is pretty awkward, but probably shouldn't
be changed at this point because it would create huge backward
compatibility issues.)

[Gimp-developer] how to call a plugin

2007-03-14 Thread Luis A. Florit 
Pals,

I am feeling so silly in trying to develop a plugin...
I am stalling even at the most easy tasks.

Now, I just want to blur my drawable from my plugin.
I tried this:

  GimpParam *rreturn_vals;
  gint nnreturn_vals;
  rreturn_vals = gimp_run_procedure("plug_in_blur", &nnreturn_vals,
  GIMP_PDB_INT32, GIMP_RUN_NONINTERACTIVE,
  GIMP_PDB_IMAGE, param[1].data.d_image,
  GIMP_PDB_DRAWABLE, gimp_drawable_get (param[2].data.d_drawable),
  GIMP_PDB_END);

However, I get the following error:

Procedure 'plug-in-blur' has been called with an invalid ID for
argument 'drawable'. Most likely a plug-in is trying to work on a
layer that doesn't exist any longer.

What am I doing wrong?

Sorry for the silly questions and thanks!

Luis.
