Image glitch experiment. HyperDither | John Balestrieri. HyperDither is an OS X image processing utility that converts color or grayscale images to 1-bit black-and-white using a sophisticated dithering routine. Specifically, HyperDither implements the “Atkinson” dithering matrix. History Years ago, during the development of the first Macintosh, Bill Atkinson (of HyperCard, QuickDraw, MacPaint, and now nature photography fame) discovered a very elegant dithering filter to convert greyscale image data for the 1-bit black-and-white Mac video display. The dithering produced by this routine was much higher in quality than the now-ubiquitous Floyd-Steinberg or “error-diffusion” filter (used by QuickTime, Photoshop). 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. Usage To process an image with HyperDither, just drag and drop or copy and paste the image into HyperDither’s main window.
