Hyperdither使用优雅的减色（抖动）例程将彩色或灰度图像转换为黑白或灰度。 这种技术产生的视觉效果产生了丰富的天鹅绒般的色调，并且比Photoshop提供的“ Diffusion Dither”方法具有更高的质量。
HyperDither uses an elegant color reduction (dithering) routine to turn color or grayscale images into black and white or grayscales. The visual effect produced by this technique creates rich, velvety tones, and is higher-quality than the “Diffusion Dither” method offered by Photoshop.
HISTORY:
In the early 1980s, while developing the graphics technology for the first Macintosh, Bill Atkinson (HyperCard, QuickDraw, MacPaint) discovered a very elegant filter to convert greyscale image data for display on the Mac’s 1-bit black-and-white screen.
Later, this graphics routine was implemented as an option in Apple’s HyperScan software, connecting early Macs to flatbed scanners, and nowhere else. HyperScan and the excellent Atkinson dithering routine were subsequently unavailable for many years—but not forgotten!
