emwin直接创建控件iconview，不带透明通道。添加了位图信息，只能显示一个位图图标出来，其他的都不显示
控件iconview大小是320*480，添加的位图图标大小是320*49，想用这个做菜单栏，共有十三个菜单，一页显示八个
并且设置了背景色好像没起作用还是白色的底色
/* app 图标描述结构体 */
typedef struct {
const GUI_BITMAP* pBitmap; /* app 图标 */
const char* pText; /* app 图标名字 */
}BITMAP_ITEM;
/* ICONVIEW 显示的 APP 图标 */
static const BITMAP_ITEM BitmapItemTab1[] = {
