イメージアップロードスクリプト - サイズ変更の方法

Question

私はプログラミングに慣れていないため、以下の問題について助けが必要です。

以下のスクリプトを使用して、画像のアップロードを制御しています。
1024x768に画像のオートライザーを追加する簡単な方法はありますか？

あなたはまた、このようなコマンドを使用して、imagemagicとしてサーバー側のツールを使用することができ、クライアント側でのいくつかのfileuploaderで画像のサイズを変更することができます。

`convert $original_path -resize '1024x768^' -gravity Center -crop '1024x768+0+0' $resized_path`;
