XML Object Definitions

If the number of colors in the image is not reduced to match the phone capabilities, the image will be

dithered by the phone and yield less than desirable results in most cases. To reduce the number of colors

in a graphics editing program, such as Adobe Photoshop, use the “Posterize” command. The “Posterize”

command takes one value as input for the number of color tones per color channel. For example, using

the value of 16 (4-bits per channel = 16 tones per channel) will correctly dither the color palette of the

image for the best display results on the Cisco

Unified IP Phone 7970G.

Figure 3-7 shows a CiscoIPPhoneImageFile object on a Cisco Unified IP Phone 7970G display.
