deleting multiple colors

[sabatino]

hi,
there is a function to delete a color this way:

var format = "png files(*.png)|*.png|";
var path = Dialogs.fileSave(format, "", "");
image.save(path, 1, 0xFFFFFF);

but is there a way to delete multiple colors??
that'd be nice
something like this:

var f = "png files(*.png)|*.png|";
var path = Dialogs.fileSave(f, "", "");
image.save(path, 1, 0xFFFFFF, 0x123456, 0xFFF123);
