There is a much easier way to integrate scanners into your applications on  
NeXT.  HSD provides a free toolkit which has all the hooks to SCSI already  
handled.  In addition, the toolkit supports 2,400 dpi line art interpolation,  
gray spectrum enhancement, 24 bit color, multiple active scanners, multiple  
active scan windows, batch mode scanning, sheet feeders, as well as the regular  
things like brightness, contrast and threshold.

If you would like a copy, I can send it to you on NeXTMail.  Otherwise, send me  
a self addressed stamped envelope with a diskette.

Oh, by the way, the toolkit only supports HSD scanners.
