rescaling

Mia-2
hi,

i am doing an image analysis of body shape of fish, thus i was wondering
if anyone knows wether imagej allows for rescaling all the fish to the
same total lenght (i am interested in the x and y coordinates of certain
landmarks)? all suggestions are welcome...

Cheers,
Silje

You probably need aligning, too, right? The easiest would be if you had
two very reliable landmarks, which you have to provide with each new fish.
Then, you could calculate the angle the image has to be rotated, and the
offset it has to be translated to. This could be done by a macro.
