Some icons may have a specific outline shape or may have areas inside where you want the background to show through. You can help make your interface more intuitive by using images as icons for status indication and for touch buttons. Ensure that your original image is in a format supporting transparency. You can load transparent PNG images to EVE using CMD_LOADIMAGE or you can convert them using EVE Asset Builder (https://brtchip.com/eab/). When converting the images, ensure that you convert to a format supporting transparency (alpha) such as ARGB1555 or ASTC.
