在Illustrator CS5中是否可以同时为多个对象指定以像素为单位的宽度？
Answers:
令人敬畏的约翰·旺德斯（John Wundes）为此制作了剧本（无隶属关系）。
这称为“ 设置所有事物”，在此处进行了说明，并允许您为所选对象设置宽度和高度。
如果您知道所选项目的名称（或者在Illustrator脚本指南或链接的博客文章中查找它们的名称），它也可以为所选项目设置其他值。
这是一个直接下载链接，如果由于某种原因该链接中断或不可用，这是当前（2012年10月）复制和粘贴的代码，包括顶部的John帮助说明和末尾的原始版权声明。它说的是CS-CS4，但我在CS5和CS6中都能正常工作。John Wundes的所有信誉，权利等。

// Wanna Batch Transform objects? Illustrator has built in tools to resize each selected item,
// but only by percentage, not by hard values. I made this script because I could find no
// native way to set the width of all selected objects to 100px at once.
//
// This script can accept multiple parameters at once.
// To change, for instance, both width and height at the same time,
// at the 'attributes' prompt, enter <b>width,height</b>
// then at the 'values' prompt, enter a comma separated value list like <b>20,30</b>
// If a single value is passed for 'values', that value will be applied to all chosen properties.
//
// Common legal parameter names include, but are not limited to: <b>width,height,top,left</b>.
// Install and use <a href='http://wundes.com/JS4AI/#explore.js'>explore.js</a> on an object to see what other properties can be set.
//
// Update: Based on feedback from user Jode, You are now given the option to transform objects from center.
// You can now also use whatever standard units you like and the script will convert them into pixels.
// e.g., you can enter "30mm" or "12in" and the script will know what you mean.
// v1.2 adds decimal support and explicit 'px' and 'pt' units to the regex. (thanks to Cristofer Cruz for noticing the bug)
