/* ric.h -  Ricoh IS-30 scanner constants, typedefs, function declarations
   The scanner program `rscan' creates a file (typically >1Mbyte).
   It has an ascii header, terminated by \n\n -- see RIC_hdr for its data fields.
   The rest is binary scanner data. Each `RIC_hdr.bpl' bytes holds one scan-line's
   pixels, 1 bit/pixel.  A `1' bit means black.  The order of the bytes in a line
   is left-to-right across the page.  The low-order bit in a byte is the left-most.
   Conventionally, X-coordinates start at 0, at the left of the page, and
   increase to the right.  Y-coordinates start at 0 at the top of the page,
   and increase down.
