Possible Usage Scenarios
Earlier, Aspose.Cells would create PdfBookmarkEntry for a normal sheet. But now Aspose.Cells can also create PdfBookmarkEntry for chart sheets. Since a chart sheet does not have any other cells except cell A1, it will create a PdfBookmarkEntry for cell A1 only.
Create PdfBookmarkEntry for Chart Sheet
The following sample code loads the sample Excel file which has four sheets. Two of them are normal sheets and the other two are chart sheets. It creates four bookmark entries as follows
- Bookmark-I
- Bookmark-II-Chart1
- Bookmark-III
- Bookmark-IV-Chart2
The following screenshot shows the output PDF generated by the sample code for a reference.
