also, nikolay, you may have seen the "automatic histogram xform" thread. i *swear* i used blink to apply a HT to each image and save them to disk with the HT applied, but i can't duplicate the behavior. the Animation script works when i try to do this. in blink i've both tried to copy the files and to save a crop from blink and the HT is not applied to the saved file.
i am not sure what version of blink i am running. as far as i can tell i have never compiled your source code, so it must be the default version that comes with 1.7.
