I have written my own scanner controler (using JNI, so I can scan from Java).  
My scanner here is an Epson Perfection 2400.  When I go through and list all 
the options for it, I get:
 
 Option name: mode
 Option name: depth
 Option name: halftoning
 Option name: dropout
 Option name: brightness
 Option name: sharpness
 Option name: gamma-correction
 Option name: color-correction
 Option name: resolution
 Option name: threshold
 Option name: zoom
 Option name: red-gamma-table
 Option name: green-gamma-table
 Option name: blue-gamma-table
 Option name: cct-1
 Option name: cct-2
 Option name: cct-3
 Option name: cct-4
 Option name: cct-5
 Option name: cct-6
 Option name: cct-7
 Option name: cct-8
 Option name: cct-9
 Option name: tl-x
 Option name: tl-y
 Option name: br-x
 Option name: br-y
 Option name: quick-format
 Option name: source
 Option name: film-type
 Option name: focus-position
 Option name: bay
 Option name: adf_mode
 
 That is just using the API.  Strangely, there is no "preview" option listed.  
Does this scanner have a preview option?  Is there some other way to list them?
 
 SANE API is cool, btw.  It was pretty easy to get it set up and start doing 
scans in Java.  In fact, with gcj, I could even release a binary of this 
scanning software.

"Preview" is not an option, it's a function of the frontend: Just scan the
whole scan area with a low resolution.
