4.2.2 Icons
4.2.2.1 Implementation on the 55i/57i/57iCT/6735i/6737i
On top of images, the 6755i, 6757i, 6757i CT, 6735i and 6737i support icons in some XML objects:
 TextMenu
 Custom softkeys
Format
The icons use the same encoding format than the images: two hex characters map to one byte of
pixel data, where each bit represents a pixel, the icon data describes the icon from left to right.
Icons are 8 pixels high and a multiple of 6 pixels wide.
As the font used by the phone is 7 pixels high, in order to align the icons with the labels, it is
recommended to use icons with the first row of pixel (from the bottom) empty. Also it is
recommended to leave the last column empty to leave a space between the icon and the label.
In the following example which is a single cell icon, it is recommended to use 5x7 icons.
