From: "Luis A. Florit" <gimpdevel@xxxxxxxxxxxxxxxxxxxxxx> > [ . . . ] > My questions: When to use one and when two iterators?

The gimp_pixel_rgns_process method handles the data tile by tile, which means that it is impossible, or at least quite difficult, to handle interactions that extend across multiple tiles. It is mainly useful -- and very efficient -- for plugins that act on individual pixels. Your plugin, because it needs to look at neighborhoods, does not fall into that category. -- Bill ______________ ______________ ______________ ______________ Sent via the CNPRC Email system at primate.ucdavis.edu _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
