携帯端末で表示される画像を端末側で取り込めないようにする処理、キャリア毎に対処する方法をあげられています。これはナイス情報ですね。ありがたいです。

Artichow を使ってグラフを描いてみる – れぶろぐ (2007-10-20)で、PHPでグラフを描くためのライブラリを調べられていましたので、参考にさせていただきますm(_ _)m

* ライセンスが public domain
* 3D っぽいグラフが描ける
* グラフの見た目がなんだか綺麗

というわけで、Artichowが良いとのことです。

とりあえず、画像を読み込んで、縮小して、保存のメモです。Imagick2です。

[php]
$imagick = new Imagick();
$imagick->readImage(LOAD_FILE_NAME);
# $imagick->setimageformat(‘jpg’);
$width = 400;
$height = 300;
$imagick->thumbnailimage($width, $height);
$imagick->writeImage(SAVE_FILE_NAME);
[/php]

一通りのことは出来るんですが、詳しいドキュメントが欲しいですね。
