[sane-devel] Re: epson: scanimage threshold option not working in 1.0.12 backend (Peter Santoro)

[Peter Santoro]

Ok, I believe I've figured this one out.  The function handle_depth_halftone (epson.c) indicates that for threshold to 
be enabled, the mode must be Binary and halftoning must be None.  After adding in some fprintf (to stderr) statements, I 
discovered that the order of the command line arguements also matters with these options.  I seem to remember reading 
this somewhere, but I must have forgotten.  Epson's Image Scan! for Linux 1.4.0 still doesn't work.  I'll try their new 
1.5.1 release.

I apologize if I caused anyone to waste time on this.
