Choose your combination of image format

and compression from the methods dis-

played in the drop-down dialog.

Note: The format compression choices

within the drop down list will vary depen-

dent upon the selected Data Type. See

“Guidelines for Format and Compression”

on page 76. for further information on each

of the available techniques.

Dithering

Method

(b/w only)

Select the dithering method for black/white images from the drop-down

dialog.

• None (recommended for text)

•Dithered (recommended for photos)

Converts pixels with gray values above the middle gray level to

white, and pixels with gray values below the middle gray level to

black

• Error diffusion

(also recommended for photos) Evaluates the gray-level value of

each pixel and converts it to either a black or a white value. The

amount of error is transferred to surrounding pixels before they

are converted. In this way, the error is diffused throughout the

image

Both of the available dithering methods result in a grainy, film like tex-

ture.
