Measuring Percent Coverage Using a Document Scanner Attached To a
Personal Computer

      Disclosed is a system to facilitate the measurement and
calculation of the area covered by toner or ink on a printed or
copied sheet of paper.

      An IBM 3118 Scanner is used as an input device to a computer
for the purpose of scanning a document.  Once a document is scanned,
the image is stored in computer memory as binary information.  The
image data is analyzed and computed to produce a resulting percent
coverage based on the physical size of the paper scanned.

      The software program was designed using the IBM PASCAL
Compiler/2* and the ISF2 Image Support Facility.  Scanner control,
image manipulation, and data output are provided as callable routines
in the ISF2 package (*).

      System requirements include any model of personal computer
configured with sufficient memory and disk storage space, the IBM
3118 Desk-top Scanner and hard-copy output device (printer).
