HyperDither Editor's review

The dither routine was implemented as an option in Apple's long-gone HyperScan software (A HyperCard stack with some XCMDs/XFCNs) that would connect an early Mac to a flatbed scanner. HyperScan, and hence the most-excellent Atkinson dithering routine, has been unavailable for many, many years - but not forgotten! I was able to email Bill Atkinson in January, 2003 and inquire about the details of the algorithm; he was kind enough to respond with a brief write up of the routine - 15 minutes later I had it up and running. It's taken a few spare afternoons since 2003 to pack everything into a nice little application with documentation and an icon - better late than never.
