Note The 6900 series IP phones does not display the Title and Prompt menu fields at the same time. If both Title and Prompt fields are defined at the same time, then these phones display only the Prompt field.

The CiscoIPPhoneImage object definition includes two familiar elements: Title and Prompt. These elements serve the same purpose as they do in the other CiscoIPPhone XML objects. The Title displays at the top of the page, and the Prompt displays at the bottom.

Use LocationX and LocationY to position the graphic on the phone display. Position the upper, left corner of the graphic at the pixel defined by these two parameters. Setting the X and Y location values to (0, 0) positions the graphic at the upper, left corner of the display. Setting the X and Y location values to (-1, -1) centers the graphic in the services pane of the phone display.

Use Width and Height to size the graphic. If the values do not match with the pixel stream specified in the Data field, results will be unpredictable incorrect.

Depth specifies the number of bits per pixel. Cisco Unified IP Phones support a maximum value of 2. A bit depth of 1 is black and white.

The Data tag delimits a string of hexadecimal digits that contain the packed value of the pixels in the display. In the Cisco Unified IP Phone, each pixel has only four possible values, which means that you can pack four pixels into a single byte. A pair of hexadecimal digits represents each byte.

Figure 3-3provides an example of the mechanics of pixel packing. Scanning from left to right in the display, the illustration shows the process for packing consecutive pixel values of 1, 3, 2, and 0. First, the pixels get converted to 2-bit binary numbers. Then, the binary pairs get re-ordered in sets of four to create a single re-ordered byte, which two hexadecimal digits represent.
