Chapter 6 Customizing Cisco IP Communicator
Creating Custom Background Images
Tip Many graphics programs provide a feature that will resize a graphic. An easy way
to create a thumbnail image is to first create and save the full size image, then use
the sizing feature in the graphics program to create a version of that image that is
25% of the original size. Save the thumbnail version using a different name.
The PNG files for background images must meet the following requirements for
proper display on Cisco IP Communicator:
• Full size image—320 pixels (width) X 212 pixels (height).
• Thumbnail image—80 pixels (width) X 53 pixels (height).
• Color palette—Includes up to 12-bit color (4096 colors). You can use more
than 12-bit color, but Cisco IP Communicator will reduce the color palette
to12-bit before displaying the image. For best results, reduce the color palette
of an image to 12-bit when you create a PNG file.
Tip If you are using a graphics program that supports a posterize feature for
specifying the number of tonal levels per color channel, set the number of tonal
levels per channel to 16 (16 red X 16 green X 16 blue = 4096 colors).
