Il y a un script pour ça par le génial John Wundes (pas d'affiliation).
Il s'appelle Définir TOUTES les choses , expliqué ici , et vous permet de définir la largeur et la hauteur des objets sélectionnés.
Il peut également définir toute une série d'autres valeurs pour les éléments sélectionnés, si vous connaissez leurs noms (ou si vous recherchez leurs noms dans le Guide de script Illustrator ou dans cet article de blog lié).
Voici un lien de téléchargement direct et si, pour une raison quelconque, le lien se casse ou devient indisponible, voici le code actuel (octobre 2012) copié et collé, y compris les notes utiles de John en haut et la notice de copyright originale ajoutée à la fin. Il indique CS-CS4 mais je l'ai bien fonctionné dans CS5 et CS6. Tous les crédits, droits, etc. à John Wundes.

// 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)

Si tous vos objets sont en fait des images trouvées à l'origine dans un répertoire, vous pouvez d'abord les redimensionner avec imagemagick:
Cela redimensionne tous les fichiers png dans le répertoire en cours pour avoir une largeur de 80 pixels et les écrit dans le
temp_dirrépertoire.la source
