    1111In addition the the fixed built-in standard frames MUI offers custom bitmap frames. Such frames require a truecolor screen to be displayed and offer full 8bit alpha blending.
    1212There are a few rules to be obeyed when designing your own custom bitmap frame:
    13 * the bitmap frame should be saved as PNG. The PNG image format is able to save transparency information (alpha channel) with a depth of 8 bits. In contrast to that GIF and ILBM files can handle a single transparent color only (1 bit depth).
     13* the bitmap frame should be saved as PNG. The PNG image format is able to handle 24bit truecolor image data along with transparency information (alpha channel) with a depth of 8 bits. In contrast to that GIF and ILBM files canhandle 8bit image data with a single transparent color only (1 bit depth).
    1414* the bitmap frame image consists of 3 square base images each of which is devided up into 9 subsquares. The first (left) base image represents the normal/unpressed state of the frame. The second (middle) image represents the selected/pressed state of the frame. The third (right) image represents the frame and the content area. The full bitmap frame image must have an aspect ratio of 9:3, the subparts must have an aspect ratio of 3:3. For example, a frame design with 24x24 pixels must have a dimension of 72x24 pixels.
    1515* the "corner" parts will be drawn as they are, the "side" parts will be drawn repeatedly up to the final frame dimension.
