Hi Christophe,

The following plugin should do exactly what you want. Until now it only
works with 8 bit images.

Cheers Arne

Betreff: Unique Image to Stack ?

Before I go on and write the macro to do that,
Does anybody know if I can quickly use an image and expand it to a
stack, let's say of 121 times this same image ?
Seems silly, but it would be usefull for me because I want to overlay a
fluorescent time-lapse (so, a stack) with a unique transmission image
taken at the first time point (so, a unique image), and get a movie (so,
a stack) of the overlay.
SO I want to use RGB merge or RGB+Gray merge, but First I have to get my
transmission image to a stack the dimension of my time-lapse fluorescent
sequence...

Thank you !
