Java图片旋转，使用Java语言编写程序，旋转图像文件，期间用到了滑动条jSlider事件处理技术，得到旋转角度（弧度制），图像缓冲区创建、创建bufImage的图形环境、让用于显示的缓冲区图像指向过滤后的图像、重载容器的paintComponent()方法等。-The Java Image rotation, using the Java language program, rotate the image file used during the the slider jSlider event processing technology, the rotation angle (in radians), the image buffer to create create bufImage graphical environment, so the buffer for display image point to the filtered image, reload containers paintComponent () method.
