(I assume it's +SC0.55 +EC0.79. Be sure of your parameters before rendering 
anything !!!!)

To your question: not exactly. Zoomin.inc is a macro that creates a camera 
definition according to the partial render parameters you give to it *** in 
your scene code ***. If you're using this macro, you must no pass the 
partial render parameters in the command line (or in the ini file). You must 
give them to the macro.

If you don't want to modify your scene code to use zoomin.inc, you can 
simply render your scene file using +w6400 +h4800 +SR0.44 +ER0.64 +SC0.55 
+EC0.75. It will give you a 6400 x 4800 image containing a "useful" (i.e. 
non-black) 1280 x 960 area, corresponding to 1/25 of the image, that you can 
extract with CorelDraw, Photoshop etc. Make a try with a 640 x 480 image 
first to make sure you got the technique right (you should get a 128 x 960 
useful area).
