[sane-devel] I have achieved ADF duplex scan

[Frank]

I have a suggestion concerning the duplex function using the  
SANE-Backends-1.0.19 : on my hp5590, it writes recto and verso on the same  
page, and they are upside down. Being on the same page, I cannot use a  
tool like pdtfk to rotate the part I want.
The suggestion would be to write them on separate pages. Another  
improvement would be to have a parameter for choosing longside or  
shortside binding, so as to force rotation of everyother page or not. The  
ultimate improvement would be to ocr the pages to rotate them whenever  
necessary, a costly improvement that would not bring that much to the two  
other options.
