Choose your combination of image format

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.
