つかいかた

下記の Small size の .png ファイルで試してみる。

pitr_Rocket_icon.svg.thumb

% imageOptim -a -q -d ./img
Running ImageAlpha...
find: /var/folders/hj/908kn5w57x3152grk2mt2rrh0000gn/T//imageoptim-cli/png: No such file or directory
Running ImageOptim...
./img/pitr_Rocket_icon.svg.thumb.png was: 4.406kb now: 3.553kb saving: .853kb (19.00%)
TOTAL was: 4.406kb now: 3.553kb saving: .853kb (19.00%)

4.406kb → 3.553kb 19％削減しました。
最初のエラーは、ImageAlpha が指定しているパスが間違ってるバグなのかな？

Version 1.7.10 で、修正対応してくれるそうです。

Version 1.7.10（2013/12/12 03:05）

速攻で対応頂いたみたいで試してみました。

% imageOptim -a -q -d ./img
Running ImageAlpha...
Running ImageOptim...
./img/pitr_Rocket_icon.svg.thumb.png was: 4.406kb now: 2.924kb saving: 1.482kb (33.00%)
TOTAL was: 4.406kb now: 2.924kb saving: 1.482kb (33.00%)

2924 byte でした。さらに最適化されましたね。

grunt-contrib-imagemin

grunt-contrib-imagemin で最適化した結果は、2974 byte でした。

Grunt

ImageOptim, ImageAlpha and JPEGmini for Mac. を grunt から動かします。

補遺

Adobe Unit Types.osax

古い Adobe 製品を利用していると、下記のエラーがでるよう。

上記の「Adobe Unit Types.osax」というファイルを入れ替えると解決した。
