100% brand new and high quality Features: Made of high quality material, strong, durable and good conductivity, long service life. There are up to 64 colors (RGB, 2 bits per channel + transparency). It features one or more bitmaps, even bitmaps of different sizes. Bitmaps (frames) can be selected in order to create an animation. Support an unlimited number of images. However, the big images and a lot of images will reduce the frame rate and may produce flicker. When there is enough memory (at low resolutions such as 320200), two screen buffers can be allocated for double buffering.
