I use: pdb.gimp_vectors_bezier_stroke_new_ellipse So I think it's what you are talking about, just the absolute name is different. > What does prevent you from using the calls for > gimp_vectors_bezier_stroke_new_moveto and > gimp_vectors_bezier_stroke_lineto to draw lines? I looked for "draw" and did not find functions that do it. So, in short words: I did not found thos functions. > (Don't forget to alias then in your code to shorter names, last you > have really undereadable stuff) If it does not eat up too much ressources in Python... ...you mean using def for creating a function that just calls the other one? or are "alias"es what Python offers as a separate feature?

(Help menu - > Procedure browser) - I use the procedure browser. But it does not help me, if I look for names that aren't there.... ...if I look for "draw" I got nothing.

That would be very interesting to me, especially for some other scripts, where I think about even more intensive work.

Thanks for all that hints. :) Ciao, Oliver _______________________________________________ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
