This backend +should be considered +.B beta-quality +software!

Grayscale +will produce 256 levels of gray (8 bits). Color will produce a 24 bits +color image. + +.TP +.B \-\-resolution +selects the resolution for a scan. The scanner can do all resolutions +between 1 and 300, in increments of 1. + + +.TP +.B Geometry options + +.TP +.B \-l \-t \-x \-y +control the scan area: \-l sets the top left x coordinate, \-t the top +left y coordinate, \-x selects the width and \-y the height of the scan +area.

Possible values are +.I Diamond +, +.I 8x8 Coarse Fatting +, +.I 8x8 Fine Fatting +, +.I 8x8 Bayer +and +.I 8x8 Vertical Line + +.TP +.B \-\-preview +requests a preview scan. The resolution used for that scan is 28 dpi +and the scan area is the maximum allowed. The scan mode is user +selected.

E.g., +a value of 128 requests all debug output to be printed. Smaller levels +reduce verbosity. + + +.SH LIMITATIONS +The windows TWAIN driver has many more options than this SANE +backend.
