Converting bitmaps to the Blackand White color mode

You can convert a bitmap to a 1-bit black-and-white bitmap. The Black-and-White color mode provides seven options: Line Art, Ordered, Halftone, Stucki, Jarvis, Floyd-Steinberg, and Cardinality-Distribution. Jarvis, Stucki, and Floyd-Steinberg are types of error-diffusion conversions. Error diffusion is best suited to photographic images.

An image is converted from the RGB color mode to the Black-and-White color mode.

High Contrast Art

Line Art

Line Art produces a high-contrast, black-and-white bitmap. You specify a value indicating all colors below that value turn black and all colors above that value turn white. No halftone is applied to the bitmap.


Ordered organizes gray levels into repeating geometric patterns of black and white pixels. Solid colors are emphasized and image edges are hard. This option improves the quality of the displayed bitmap for monitors that have less than 256-color capabilities. Ordered approximates pixel values by using fixed dot patterns.


Halftone creates different shades of gray by varying the pattern of black-and-white pixels in an image. Similar to a photograph, Halftone enables printing to a black-and-white laser printer.


Jarvis error diffusion applies the Jarvis algorithm to individual pixels. Stucki

Stucki error diffusion applies the Stucki algorithm to individual pixels. Floyd-Steinberg

Floyd-Steinberg error diffusion applies the Floyd-Steinberg algorithm to individual pixels.
