日常开发工作中,经常碰到要对图片进行一些简单的处理,不需要动用PS,在mac上就有一个很好的命令行工具:sips
这里我们不具体展开讲,仅贴出几个常用的操作示例,更多用法请大家自行研究
自适应裁剪图片
sips -Z 600 meinv.jpg
其中600表示高度为600px,宽度为按比例缩放
固定宽度
sips -z 100 200 meinv.jpg
其中100表示高度为100px,宽度为200px
旋转
sips -r 90 meinv.jpg
向右旋转90度
水平方向/垂直方向翻转图片
sips -f horizontal meinv.jpg
sips -f vertical meinv.jpg
最后附上spis的帮助信息
