切图严格来说并不是UI设计师的工作, 而是前端工程师的工作,指的是将UI设计师的设计(大部分为photoshop创建的PSD文件）转化为界面（网页或窗体等）所需要资源的过程。<br />切图是衔接UI设计和应用程序的桥梁，是一种将设计师的“理想”转化为“现实”的工作。 由于不同人的实现方法不同，可能对切图的需求也存在一定的差异。作为前端工程师，掌握切图将为提升自己的竞争力带来一臂之力。<br /> 一般来说，photoshop可以通过手动进行切图，这样比较好控制，但是对于复杂的UI来说，往往比较费事费力。photoshop 从CC版开始对于切图的功能进行了提升。可以自动对PSD文件按图层进行自动切图（原理就是模拟人的操作，将其他图层设置为隐藏，然后对待切图的图形进行裁剪，并支持透明背景）。下面用step by step介绍一下photoshop CC如何实现自动切图：<br />1、准备UI资源文件(一般为美工提供PSD文件）login-form.psd<br /><br />2、用photoshop （CC 2015）打开该文件，图层结构如下：<br /><br />3、photoshop中选择【文件】【导出】【将图层导出到文件】，如下图：<br /><br />4、打开导出到文件配置对话框，（默认将存放目录放于桌面）如下图：<br /><br />选择PNG-24,勾选上透明区域、交错和裁切图层。<br />5、单据【运行】，效果如下：<br /><br />6、根据UI复杂度不同，等候的时间不同,最后切图后的资源如下图所示（移动到文件夹中）：<br /><br /><br />
