how to call a plugin

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.

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.)

Hi Bill,

Yep, it worked!
Thanks a lot!!
