Abstract: This library of FORTRAN subroutines supports a flatbed
digitizing tablet. It was written for a 'Summagraphics'
tablet interfaced via a RS232 port to a MINC 11/23 lab
computer running RT-11, but is readily adaptable to
other hardware. No intelligence of the digitizer is
assumed, except that a curser - set hardware origin of
axes may be used. The routines can set a local origin of
axes and axes orientation, a scale factor and allow
transmission of messages to the calling program from a
'menu' area on the digitizer. Routines are provided for
digitizing cine-film type material and creating a
structured data file. Error correction can be made on
individual points or whole frames can be redigitized.
The routines are written to minimize memory usage. A
program using DIGLIB for measurement of the enclosed
area within a digitized shape is also included.
