JavaScriptを介したC++で指定したワークシートをPDFに保存

デフォルトでは、Aspose.Cellsはブック内のすべての表示されているワークシートをPDFに保存します。PdfSaveOptions.sheetSet オプションを使用して、特定のワークシートだけをPDFに保存できます。例:アクティブなワークシートをPDFに保存、すべてのワークシート(表示および非表示)をPDFに保存、複数のカスタムワークシートをPDFに保存など。

アクティブワークシートをPDFに保存する

アクティブシートのみをPDFにエクスポートしたい場合は、PdfSaveOptions.sheetSetSheetSet.activeを渡すことで実現できます。

シート「Sheet2」は、ソースファイルsheetset-example.xlsxのアクティブシートです。

すべてのワークシートをPDFに保存

SheetSet.visibleはブック内の表示されているシートを示し、SheetSet.allは表示・非表示に関わらずすべてのシートを含むものを示します。すべてのシートをPDFにエクスポートしたい場合は、SheetSet.allPdfSaveOptions.sheetSet オプションに渡すだけです。

ソースファイル sheetset-example.xlsx には、非表示シート Sheet3 を含むすべての4つのシートが含まれています。

指定されたワークシートをPDFに保存

複数の目的のシートやカスタムシートをPDFにエクスポートしたい場合は、複数のシートインデックスをPdfSaveOptions.sheetSetに渡すことで実現できます。

ワークシートを並べ替えてPDFに変換

ソースファイルを変更せずにシートの順序(例:逆順)を変更してPDFに出力したい場合は、並び替えたシートインデックスを PdfSaveOptions.sheetSet オプションに渡すことで実現できます。
