Photoshop切图批处理脚本

http://www.wxwdesign.com/archives/photoshop%E5%88%87%E5%9B%BE%E6%89%B9%E5%A4%84%E7%90%86%E8%84%9A%E6%9C%AC



类似Google地图的东西，整个地图尺寸很大，要在网页上用，需要切成小的碎片，Google地图的每一片是256px*256px。

目前恰好遇到了这样一个问题，手里拿到了一张很大的图，需要切成碎片，粗略算了一下，最后生成的切片大概2000张左右，如果手工一点一点的切，按10秒/张的速度，需要连续不停地切5.56个小时，擦，这不是闲得蛋疼吗？

于是乎，想到了用批处理，但这个工程又不是个简单的批处理，只有一个原图，需要把一张图切成2000张，最后感觉还是用脚本比较合适。

这种脚本在百度和谷歌里很难找，一个用PS做设计的人，难道你想让她琢磨脚本程序？搜了一番，发现还是有人写过PS的脚本，下载来参考了一下，又到Adobe官网下载了Scripts参考手册，自己也写了一个切图的脚本。

另外推荐一个PS脚本论坛，感觉比adobe的官方论坛还要好一些。(http://ps-scripts.com/)

WordPress编辑器贴代码真蛋疼，不太好用，还不如UBB好用，拿到IDE里格式化一下就好了。
