Even the act of loading a file into memory as pixel data and then recompressing on save is lossy for lossy formats and grayscale formats outright destroy information if the original is color. It is not realistic to keep track for each format feature by feature, if the image is now restorably exported or not, it would make maintaining gimp code and adding features a horror... Each change anywhere would recquire going over all export plugins making sure their supported feature lists are up to date... This separation makes it clear cut. The project file, the one that keeps ervery feature of gimp intact is the xcf and you save to it. Any rendering you export to. And this distinction will get even more important when we get to gegl backend in full. In short, options were considered, arguments have been had. We didn't do this to anoy anybody, we did this based on alot of consideration and a future of GIMP as a nondestructive image editor. -- --Alexia _______________________________________________ gimp-developer-list mailing list gimp-developer-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gimp-developer-list
