Thank you.

Hack it is, not portable, ...  I had considered something like
GENESYS_HAS_PDFS_SW and GENESYS_HAS_PDFF_SW, but it would have to integrate
with all the other interfaces and scanners.  And the start,

And then I considered one button for color PDF and the other for black and
white - perhaps something more generic would be better, like PDF0 and PDF1.
Or just have them all generic (B00 through B04).

There are 4 labels and 5 buttons.  PDF has two buttons.  Left to right:

"-------- PDF ---------"   "AUTO SCAN"    "COPY"     "E-MAIL
 B00          B01           B02            B03        B04

Button      Map    Mask  filter	
PDF START   file   x10   "^file.*"
PDF FINISH  hacked x01   "^page.*"
AUTO SCAN	scan   x02   "^scan.*"
COPY        copy   x04   "^copy$"
E-MAIL      email  x08   "^email$"           

All set up as 
   numerical-trigger { 
	from-value = 1  
	to-value   = 0

If I can be of any service please let me know.

     this button is meant for document in detection. So using it like 
this is effectively an hack. What are the buttons label on your scanner, 
especially the one of this not yet supported button ?
