Changing bitmaps to black-and-white images

You can change any image to a black-and-white image. In addition to conversion settings such as threshold, screen type, and intensity, there are seven conversion options that affect how the converted images will look.

Conversion
Line art
Produces a high-contrast, black-and-white image. Colors with a grayscale value lower than the threshold value that you set change to black, while colors with a grayscale value higher than the threshold value change to white.
Ordered
Organizes the gray levels into repeating geometric patterns of black and white pixels. Solid colors are emphasized and image edges are hard. This option is best suited for uniform colors.
Halftone
Creates different shades of gray by varying the pattern of black and white pixels in an image. You can choose the screen type, angle for the halftone, lines per unit, and the unit of measure.
Cardinality-Distribution
Creates a textured look by applying a calculation and distributing the result to the screen.
Jarvis
Applies the Jarvis algorithm to the screen. This form of error diffusion is suitable for photographic images.
Stucki
Applies the Stucki algorithm to the screen. This form of error diffusion is suitable for photographic images.
Floyd-Steinberg
Applies the Floyd-Steinberg algorithm to the screen. This form of error diffusion is suitable for photographic images.
