To my knowledge, the FLAGS parameter controls 1) whether the parasite is persistent across sessions, and 2) whether adding the parasite is an UNDOable operation. 1) is controlled by the least significant bit of FLAGS, while 2) is controlled by the second bit. This results in four possible settings: 0 - Not persistent and not UNDOable 1 - Persistent and not UNDOable 2 - Not persistent and UNDOable 3 - Persistent and UNDOable > Third list member: parasite value (must always be a string). So an > RGB colour value would have to be stringified. unstrbreakup maybe? That would work. (set! color (car (gimp-context-get-foreground))) ; as an example (set! str (unbreakupstr (map number->string color) " ")) : : (set! color (map string->number (strbreakup str " "))) > Generally: do all the gimp-*-parasite-attach methods suffer from same > bug, so should be reapplied til they work? I believe so. Yes. _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
