NAME
     cscan - Color scanner program

SYNOPSIS
     /usr/sony/bin/cscan [-pqg] [ -aXxY+W+H ] [ -dDPI ]

DESCRIPTION
     cscan drives the EPSON 300 color scanner.  It  reads  images
     in from the color scanner and allows a choice of output for-
     mats.  It also has the ability to selectively  read  only  a
     portion  of  the  scanner  window.  An option to control the
     resolution is also available.

     The options are:

     -p    The scanned image will be in PPM (Portable Pixel  Map)
           format.  The format is twenty four bits per pixel full
           color.  The pixels are packed in RGB format.  A simple
           ASCII  header,  giving  the  size  of  the  image,  is
           prepended to the raw pixels.  This is a  very  popular
           public  domain  format and it can be easily translated
           into other color formats.

     -q    A quick color scan in eight bit X  window  PseudoColor
           format.  This can be directly displayed by xwud(1) for
           quick color previews.

     -g    The scanned image with be in eight bit X  window  Sta-
           ticGray  format.   This  can  be directly displayed by
           xwud(1) for high quality gray scale images.

     -aXxY+W+H
           The area read option controls the active area  of  the
           scanner  window.   The  option  has four integer argu-
           ments.  By default, the arguments  given  are  in  one
           hundred dots per inch resolution.  The first two argu-
           ments are the X and Y offset  values  from  the  upper
           left corner of the scanner window.  The last two argu-
           ments, W and H, are the width and height in pixels  to
           scan  respectively.   This option can be combined with
           the dots per inch option below to effectively zoom  in
           on a section of the scanner window.

     -dDPI This option allows increasing or decreasing  the  dots
           per  inch read by the scanner.  When combined with the
           area reading option, it can be used to read high reso-
           lution images of small sections of the scanner window.
           When the dots per inch option is given before the area
           reading  option,  the  arguments  to  the area reading
           option are assumed to be in the dots per inch  resolu-
           tion  specified.  If the dots per inch option is given
           after the area reading option, then the area specified



                                                                1

           is  scanned at the resolution given.  The area reading
           arguments are not scaled.
