解説

MicroPDF417BarcodeDataBarcodeData基本クラスから派生したクラスで、MicroPDF417バーコードの読み取りまたは書き込みに使用できる固有のデータが追加されています。

読み取りバーコード

BarcodeReaderオブジェクトがMicroPDF417(BarcodeSymbology.MicroPDF417)を検出して読み取るとき、BarcodeReader.ReadBarcodeBarcodeReader.ReadBarcodesのメソッドは、見つかったバーコードごとに、基本BarcodeDataクラスにキャストされたMicroPDF417BarcodeDataオブジェクトを返します。

NET標準のキャストによってオブジェクトをMicroPDF417BarcodeDataとして取得してから、このバーコード体系に関連する追加のデータプロパティを調べます。

ベースBarcodeDataオブジェクトで通常返されるすべてのデータメンバに加えて、このクラスには以下のメンバが追加されています。

上記のメンバに加えて、バーコードデータに関連しないそのほかの他のMicroPDF417読み取りオプションをMicroPDF417BarcodeReadOptionsクラスを使用して設定できます。

バーコードの書き込み

BarcodeWriterクラスには、画像へのバーコードの書き込みに使用するWriteBarcodeメソッドがあります。このメソッドは、ベースBarcodeDataとしてデータパラメータを受け取りますオブジェクト。MicroPDF417バーコードを書き込むには、MicroPDF417BarcodeDataのインスタンスを作成して必要なパラメーターを設定し、このオブジェクトをWriteBarcodeのデータパラメーターに渡します。

ベースBarcodeDataオブジェクトで通常通り設定されなければならないすべてのデータメンバに加えて、以下のメンバも指定しなければなりません:

上記のメンバに加えて、バーコードデータに関係しないそのほかのMicroPDF417書き込みオプションはMicroPDF417BarcodeWriteOptionsクラスを使用して設定できます。

次のように、static (Visual BasicではShared)BarcodeData.CreateDefaultBarcodeDataメソッドを使用して、画像への書き込み用に設定されたデフォルトパラメーターを含むMicroPDF417BarcodeDataの新しいインスタンスを作成できます。

[Visual Basic]


             Dim microPDF417Data As MicroPDF417BarcodeData = DirectCast(BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.MicroPDF417), MicroPDF417BarcodeData)
             

[C#]


             MicroPDF417BarcodeData microPDF417Data = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.MicroPDF417) as MicroPDF417BarcodeData;
             
サンプル

このサンプルは、異なるオプションを使用していくつかのPDF417バーコードを画像に書き込んだ後、再び読み取ります。
