1. 方法
a. 获得图片
img = Image.createImage(str); //J2ME里面代价比较高
b. 绘制图片
drawImage(Image image,int left, int top, Graphics.LEFT | Graphics.TOP);
c 安装区域绘制：
drawRegion(Image src, int x_src, int y_src, int width, int height, int transform, int x_dest, int y_dest, int anchor)
Image src, 图片
int x_src, 从这个图片的x坐标开始截取
int y_src,
int width, 截取宽度
int height,
int transform, 旋转方式（0：不旋转，1... 一直到7，你可以自己试下）
int x_dest, 画到屏幕的位置的x坐标
int y_dest,
int anchor Graphics.LEFT|Graphics.TOP
2. code
