FineReader Engine API のドキュメント関連オブジェクト — 文書とそのページを扱うための FRDocument、FRPage、FRPages、BusinessCard、および MRZ オブジェクト。 ABBYY FineReader Engine では、文書とそのページを操作するために、[FRDocument](/ja/fine-reader/engine/api-reference/document-related-objects/frdocument)、[FRPages](/ja/fine-reader/engine/api-reference/document-related-objects/frpages)、および [FRPage](/ja/fine-reader/engine/api-reference/document-related-objects/frpage) の各オブジェクトが提供されています。 FRDocument オブジェクトは、ドキュメント関連オブジェクトの階層の最上位に位置します。このオブジェクトは、解析、認識、再構成、エクスポートの各メソッドを提供します。FRPage オブジェクトは、特定のページを操作するための一連のメソッドを提供します。FRPages オブジェクトには、文書ページのコレクションが含まれています。FRDocument オブジェクトと FRPage オブジェクトには、名刺のコレクションを含めることもできます。 このセクションの他のオブジェクトでは、作成者、キーワード、件名、文書タイトル、PDF ファイルの添付ファイル情報など、文書に格納されている追加情報にアクセスできます。 このセクションには、次のオブジェクトとコールバック インターフェイスの説明が含まれています。 * [FRDocument](/ja/fine-reader/engine/api-reference/document-related-objects/frdocument) *
