MATLAB GUIツールは画面レコードを作ります

• 私が直接自分自身を補うために小さなツールを作成するMATLABと考えるので、インストールを取得していない長い時間のためのスクリーンの録音ソフトウェアは、成功したとき、彼らは壊れ主な理由は、プログラムは主に、時限ショットを取得するためにタイマーを使用して、難しいことではありませんし、GIF形式にスプライス絵、そしてあなたは、これは図形の大きさを調整することによって達成される、あなたはポイントを知っている必要があり、記録画面のサイズを指定することができますが、Javaクラスを使用することで、少し表情が分かります。

3枚の写真を保存する必要がplay.jpg、pause.jpg、停止、JPG命名しました。

結果は以下の通りであります：
