     #include <scanner.h>

     int SCGetPageSize(SCANNER *s, int metric, float *x, float *y,
		       float *width, float *height);

DESCRIPTION
     SCGetPageSize queries a scanner for the size of the scannable area.  s
     specifies a connection to a scanner previously obtained from a call to
     SCOpen(3), SCOpenFile(3), or SCOpenScreen(3).  metric is used to specify
     whether the results are required to be in inches (SC_INCHES) or
     centimeters (SC_CENTIM).  SCGetPageSize returns the x and y coordinates
     of the upper left hand corner of the scannable area in x and y, and the
     width and height of the scannable area in width and height.

RETURN VALUE
     SCGetPageSize returns 0 if successful.  In the event of an error,
     SCGetPageSize returns -1 and sets the global variable SCerrno to indicate
     the reason for failure.
