很棒的John Wundes有一个脚本（无从属关系）。

它被称为Set ALL the things，解释here，并允许您设置选定对象的宽度和高度。

^{图片来源-“清洁所有东西”}

如果您知道它们的名称（或者，如果您在Illustrator 脚本指南或链接的博客文章中查找它们的名称），它也可以为选定项目设置一大堆其他值。

/////////////////////////////////////////////////////////////////
//  Set All The Things v.1.2 -- CS,CS2,CS3,CS4
//>=--------------------------------------
// 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)

根据Adob​​e Help，没有。

您无法输入特定宽度来缩放多个对象。在 Illustrator 中，您只能以百分比测量来缩放对象。

如果所有对象实际上都是最初在某个目录中找到的图像，则可以首先使用 imagemagick 调整它们的大小：

mkdir -p temp_dir
mogrify -resize 80x -path temp_dir *.png

这会将当前目录中的所有 png 文件的大小调整为 80px 宽度并将它们写入temp_dir目录。
