バーコードを含む増分ラベルのページを作成しようとしています。バーコードをPDFに変換し、PDFの他のコンテンツにスーパーインポーズすることができます(以下を参照)。しかし、次のようなものを使用して、PDFの特定のページにバーコードを割り当てる方法がわかりません。

Zend_Barcode::factory('code39', 'pdf',
$barcodeOptions, $rendererOptions)->setResource($page)->draw();

また

$page = Zend_Barcode::factory('code39', 'pdf', $barcodeOptions,
$rendererOptions)->setResource($pdf)->draw();

上記のスニペットは両方とも、私の大きなコードのコンテキストで設定するとエラーが発生します。さらに下には、エラーなしでレンダリングされるコードがありますが、必要なものは提供されません。

この質問は、Zend Framework Render Barcodes Into PDF Pagesと同じです。これは、私が見ることができるものからは実用的な答えに到達しませんでした。

まず、これを機能させるために、Zendバージョン1.11バーコードライブラリをZendバージョン1.7.2ライブラリフォルダにコピーしました。また、コードが示すように、無料の非等幅フォントをアプリケーション/ライブラリにコピーしました。

ラベルの複数ページのPDFを作成できます。そして、PDFにバーコードを入れることができます。私ができないのは、複数のページにバーコードを配置することです。私がしていることをお見せします。うまくいけば、私が間違っていることややらなければならないことを教えてください。

まず、PDFにバーコードを入れるこの小さなスニペットがあります。

// A font path is mandatory for Barcode Pdf output.  
// This application defines ROOT_DIR in index.php.  Others may define APPLICATION_PATH.
// Monospaced fonts apparently don't work here.
$barcodeOptions = array(
    'text' => '11111',
    'font' => ROOT_DIR . '/library/Rbs/Barcode/FreeSerif.ttf'
);
$rendererOptions = array(
    'topOffset' => 50,
    'leftOffset' => 50
);
Zend_Barcode::factory('code39', 'pdf',
$barcodeOptions, $rendererOptions)->setResource($pdf)->draw();

次に、ラベルを作成するこの(長い)コードがあります。バーコードを配置することを試みた2つの主要な場所の下部近くにコメントしましたが、主要な問題は、PDFの特定のページにバーコードを配置する方法がわからないことであるようです。
