Illustrator CS5で複数のオブジェクトの幅をピクセル単位で同時に指定することはできますか？
回答:
そのための素晴らしいJohn Wundes（所属なし）によるスクリプトがあります。
ここで説明するSet all the thingsと呼ばれ、選択したオブジェクトの幅と高さを設定できます。
選択したアイテムの名前がわかっている場合（または、Illustratorスクリプトガイドまたはリンクされたブログ投稿でそれらの名前を調べる場合）、選択したアイテムに他の値も設定できます。
ここに直接ダウンロードリンクがあります。何らかの理由でリンクが壊れたり使用できなくなったりした場合は、現在（2012年10月）のコードをコピーして貼り付けます。CS-CS4と書かれていますが、CS5とCS6でうまく動作しました。John Wundesに対するすべてのクレジット、権利など。

// 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)

すべてのオブジェクトが実際にあるディレクトリで最初に見つかった画像である場合、最初にimagemagickでサイズを変更できます。
mkdir -p temp_dir
mogrify -resize 80x -path temp_dir *.png
これにより、現在のディレクトリにあるすべてのpngファイルのサイズが80pxに変更され、temp_dirディレクトリに書き込まれます。
