Skin Technology (Devices)
A skin consists of up to three bitmap (BMP) or Portable Network Graphics (PNG) files and a single Skin Definition File that contains Extensible Markup Language (XML). The Skin Definition File and the associated BMP or PNG files must be in the same directory.
The XML file describes how the skin works and where to find the BMP or PNG files. The XML file also defines button actions based on the color code shown in the mapping file. For more information, see Skin Definition File Example (Devices).
One BMP or PNG file, referred to as a normal art file, shows the default appearance of the emulator skin. The normal art file is the only file that is required for a skin.
A second, optional, BMP or PNG file, referred to as a down art file, shows the appearance of the skin with all buttons pressed.
A third, optional, BMP or PNG file, referred to as a mapping file, shows a color code for each button on the skin. The color code for each button is represented in the mapping file as a single-color area that completely covers the button. Users of the skin do not see the colors that you use as codes in the mapping file.
