解説

GS1DatabarStackedBarcodeReadOptionsクラスは、LEADTOOLSを用いてGS1 Databar Stackedバーコードを読むとき、オプションを制御するのに用いられます。オプションの設定方法は2通りあります。

BarcodeReaderクラスには、各バーコード体系(または共通バーコード体系のグループ)のデフォルトオプションが含まれます。これらのオプションを取得するには、以下のいずれかを渡してBarcodeReader.GetDefaultOptionsメソッドを呼び出します。

BarcodeReadOptionsからGS1DatabarStackedBarcodeReadOptionsまでそれをキャストすることによって、返されたGS1DatabarStackedBarcodeReadOptionsのメンバを変更します。

また、GS1DatabarStackedBarcodeReadOptionsクラスのインスタンスを作成し、単一のオプションまたはオプションの配列を入力パラメータとして受け取るBarcodeReader.ReadBarcodeメソッドおよびBarcodeReader.ReadBarcodesメソッドでそのインスタンスを直接使用することもできます。

ベースBarcodeReadOptionsのメンバとその機能を以下に示します。

メンバ 説明
BarcodeReadOptions.ForeColor

カラー画像からバーコードを読むとき、使うバーコード前景色(バーまたはシンボルのカラー)を制御します。

BarcodeReadOptions.BackColor

カラー画像からバーコードを読むとき、使うバーコード背景色(スペースのカラー)を制御します。

BarcodeReadOptions.LoadBarcodeReadOptions.Save

保存するか、XMLファイルまたはストリームへ/からオプションをロードするのに用いられることができます。

BarcodeReadOptions.GetSupportedSymbologies

このクラスは、以下のバーコード体系を格納している配列を返すために、ベースクラスメソッドをオーバーライドします:BarcodeSymbology.GS1DatabarStackedBarcodeSymbology.GS1DatabarExpandedStacked

これらの機能とメンバに加えて、GS1DatabarStackedBarcodeReadOptionsはこれらのGS1 Databar Stackedバーコードに特有の機能を格納します:

メンバ 説明
SearchDirection

バーコードの検索時に使用する方向(水平、垂直、またはその両方)。

EnableFastMode

高速バーコード読み取り(推奨)。それは、大部分のバーコード性質にふさわしいです:良好であるか、不良

データの塊

バーコードの読み取り時にスキップする列あたりのスキャンライン数

ReturnCheckDigit

エラー検査桁は、バーコードデータの一部として返されます

サンプル

このサンプルでは、さまざまなオプションを指定したいくつかのGS1 Databar Stackedバーコードをimageに書き込んだ後、再び読み取ります。
