# CopyFrom メソッド

> ABBYY FineReader Engine API の CopyFrom メソッド — 現在のオブジェクトのプロパティを、同種の別のオブジェクトの値で初期化する共通メソッド。

<Note>
  これは共通メソッドです。プラットフォーム固有の実装上の制限事項は、このメソッドを使用するオブジェクトのトピックに記載されます。
</Note>

このメソッドは、現在のオブジェクトのプロパティを、別のオブジェクトの対応するプロパティの値で初期化します。

From

\[in] この変数は、現在のオブジェクトと同じ型のオブジェクトを参照します。このオブジェクトは、新しいオブジェクトにコピーされるデータのコピー元として使用されます。
