Skin Layout
General Information
All textures must be power of two in size, rectangular textures are supported, for example, 16×16, 128×32, 8×64, etc. All files are in the RGBA format.
Icons
Layout
There are four states of an icon:
- Not pressed, not in focus.
- Not pressed, in focus.
- Pressed, not in focus.
- Pressed, in focus.
Assembly
Parts of the texture are copied 1:1.
Splash Screens
Layout
The texture is divided into two parts: the initial state (upper) and the final state (lower).
Assembly
While a texture splash screen is being displayed, the initial picture (upper) is gradually replaced with the final one (lower). Pseudo-animation can be created using the alpha channel: regions of the lower half with small alpha values will be shown first, regions with larger alpha values will be shown last.

Layout
Assembly
All four corners are copied 1:1 from corresponding corners of the texture:
- The top-left corner
- The top-right corner
- The bottom-left corner
- The bottom-right corner
Vertical and horizontal strips (2 pixels in width), which are located at the center of the corresponding half of the texture are used to fill in space between corners. The strips are stretched, and the resulting color bar is constructed using interpolation between colors of the pixels in the strips.

Layout
The texture contains four variants of buttons in different states, the same as defined for icons. Also, each button is divided into 3 parts, which are shown below.
Assembly
All four corners are copied 1:1 from corresponding corners of the texture. Vertical and horizontal strips (2 pixels in width), which are located at the center of the corresponding half of the texture and marked as 2 and 3 on the picture are used to fill in space between corners. The strips are stretched, and the resulting color bar is constructed using interpolation between colors of the pixels in the strips.
