Möjliga användningsscenario
Tidigare skapade Aspose.Cells PdfBookmarkEntry för ett normalt blad. Men nu kan Aspose.Cells också skapa PdfBookmarkEntry för diagramblad. Eftersom ett diagramblad inte har några andra celler än cell A1, kommer det att skapa ett PdfBookmarkEntry för endast cell A1.
Skapa PdfBookmarkEntry för diagramblad
Följande exempelkod laddar in prov Excelfil som har fyra ark. Två av dem är normala ark och de andra två är diagramark. Den skapar fyra bokmärkesposter enligt följande
- Bokmärke-I
- Bokmärke-II-Chart1
- Bokmärke-III
- Bokmärke-IV-Chart2
Följande skärmbild visar utdata PDF genererad av exemplet.
