The Color Depth Conversion functions implement features that change the way that colors are represented in images. Today’s devices represent colors in many different ways. Some devices, such as printers accept 1 bit monochrome images, others accept 24 bit full color images. Converting a color image to black and white is called halftoning or clustered-dot ordered dither in computer graphics. The Document Imaging SDK/ActiveX has 9 sophisticated dithering algorithm, some of them only available from Black Ice such as Stevenson Arce dithering.
