swing绘制了一只直升机

周末用swing绘制了一只直升机 对swing的的绘制技术有些总结：

1.图形基于坐标系定位 坐标原点位于左上角 分别向右（x轴） 向下（y轴）递增
2.图形按像素组成
3.重写Jcomponent的paint方法 其中的Graphics g 对象相当于画笔
4.对于特别复杂的图形无法绘制 可以用g.drawImage载入 但比较消耗资源
5.擅用g.drawArc、d.drawPloygon、d.drawPloyline 这三个函数可以画出比较复杂的图形

感觉swing对图型图像的处理相对较弱，在开发比较痛苦package com.gs.swing;

建议不要重写paint,重写paintComponent就可以了

有道理，我试下

楼主加上一下抗锯齿，效果应该会好很多的。
