Hi,
Here is some of the code that I use in order to return some int8 into an array.
gint w,h, ***fea_vector;
if (strcmp (name, PLUGIN_NAME) == 0){
vector = (guint8 **) malloc(sizeof(guint8 *));
if(get_some_pixels(image_ID,drawable,&w,&h,fea_vector)){/*put some vals*/
*nreturn_vals=5;/*in fea_vector*/
values[1].type= GIMP_PDB_INT32;
values[1].data.d_int32= h;
values[2].type= GIMP_PDB_INT32;
values[2].data.d_int32= (gint32)w;
values[3].type= GIMP_PDB_INT32;
values[3].data.d_int32= (gint32) w * h;
values[4].type= GIMP_PDB_INT8ARRAY;
values[4].data.d_int8array = *fea_vector;
I don't use Python for writing plugins but I strongly recommend you doing some
debug. You can get to the code of "_gimp_wire_write" in libgimp/gimpprotocol.c
where the plugin surely crash while writing the values of the INT8ARRAY (at
least, it was here in my case).
