[Gimp-developer] python plugin dos not receives changes to FLOATARRAY parameters done by libgimp functions.
hi! i wrote a c gimp plugin which is called from an python gimp plugin. the c plugin receives a FLOATARRAY parameter which it modifies. the c plugin sees the values the python plugin has put into the FLOATARRAY, but if it modifies these, this changes are not send back to the python plugin. how to made it work? do i have to change my python or my c plugin? do i have to modify gimps python-plugin-interface? i guess some special converter has to be written to automaticaly construct a python array from FLOATARRAYS. an equivalent question: how to use gimp_path_get_points from a python plugin? here some samplecode: def somefunc(image): floatarray = [] for i in range(100): floatarray.append(0.0) closed = 0 count = 0 gimp.pdb.gimp_path_get_points(image, path1, 1, closed, count, floatarray) return floatarray floatarray should be modified by 'gimp_path_get_points' but it's not. how to get this values transfered to the python plugin? regards kl ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

No, that's now how things work. This is how you do it: def somefunc(image): path_type, path_closed, num_path_point_details, points_pairs = \ pdb.gimp_path_get_points(image, path1) return points_pairs Return values are returned as return values, which is the python way to do things. It's not like the C API. If you browse the PDB within the python console, when you select a procedure at hit Apply, it will paste a sample of how to call it in to the console entry box. -Yosh ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
