Short answer: No. Long answer: the PNG specification allows for private format extensions, so applications can add all sorts of features and store them in a PNG file. No other application is required to support those, however. For example, Adobe/Macromedia Fireworks does this and adds vectors and layers to the PNG files (its native(iirc) file format). This tricks some users without comprehensive file format knowledge into regarding those as PNG standard features. -- Regards, Michael GPG: 96A8 B38A 728A 577D 724D 60E5 F855 53EC B36D 4CDD _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
