Page Setup Zoom Factor Creates Incorrect Number of Pages in PDF


I am testing the PageSetup.Zoom property and I have noticed a difference in the number of pages generated between the output created by Excel (printing or Export to PDF) and that by Aspose.

Page counts for zoom levels below 200 seem OK, but zoom level 200, 300 and 400 create less pages than they should.

Zoom 200% - creates 25 pages, print preview and export PDF create 30.
Zoom 300% - creates 56 pages, print preview and export PDF create 105.
Zoom 400% - creates 144 pages, print preview and export PDF create 160.

Looking at the pages, there is an extra row in the PDF created by Aspose that is not on the exported PDF or the print preview of the worksheet, and it overwrites the bottom margin - see attached image: ZoomFactorPageMismatch.png (44.4 KB)

This is my Excel sample file: PageSetup-CommentsErrorsHeadingsNotesTitles.zip (10.0 KB)

I also noticed that the the row/column headers in the resulting PDF are not drawn properly at lower zoom 10, 50, and the higher zoom levels of 200, 300 and 400.




Thanks for using Aspose APIs.

This issue occurs because Microsoft Excel changes the Pdf page size while Aspose.Cells do not change it. Please see this screenshot for a reference.

  • CELLSNET-46088 - Page Setup Zoom Factor creates incorrect number of pages in PDF


Thanks for looking into this. I’m confused as to why/how you are getting different page sizes.

In Excel, when I set the Page Setup Zoom (Scaling) to different levels, then do a print preview or Export to PDF, I still get an 8.5x11 page, both in the preview and in my resulting PDF.

In my tests here, exporting to PDF from Excel using my sample file gives the results below:

  • Scale 10% - 1 page, 8.5x11
  • Scale 50% - 1 page, 8.5x11
  • Scale 100% - 4 pages, 8.5x11
  • Scale 200% - 30 pages, 8.5x11
  • Scale 300% - 105 pages, 8.5x11
  • Scale 400% - 160 pages, 8.5x11

Saving the same Excel file via Aspose and the Workbook.Save(PDF) also gives me 8.5x11 Letter sized pages.

This is the code I am using:

Aspose.Cells.PdfSaveOptions pdfSaveOptions = null;
pdfSaveOptions = new Aspose.Cells.PdfSaveOptions(Aspose.Cells.SaveFormat.Pdf)
    // set warning callback
    WarningCallback = wbWarningCallback,
    Compliance = Aspose.Cells.Rendering.PdfCompliance.None, // creates 1.4 PDF
    OptimizationType = Aspose.Cells.Rendering.PdfOptimizationType.MinimumSize,

foreach (Aspose.Cells.Worksheet wSheet in wBook.Worksheets)
    if (!wSheet.IsVisible) continue;
    wSheet.PageSetup.Zoom = 200;

wBook.Save(OUTPUT_DIR + OUTPUT_NAME, pdfSaveOptions);
