Fit All Worksheet Columns on Single PDF Page with C++

Sometimes you want to generate a PDF file that fits all of a worksheet’s columns onto one page. The PdfSaveOptions.PaginatedSaveOptions(PaginatedSaveOptions_Impl impl)* property provides this feature in a very easy-to-use manner. Complex calculations such as the height and width of the output PDF are handled internally and are based on the data in the worksheet.

Fit Worksheet Columns on Single PDF Page

PdfSaveOptions.PaginatedSaveOptions(PaginatedSaveOptions_Impl impl)* ensures that all columns in a worksheet are rendered to a single PDF page, although rows may expand to several pages depending on the data in the worksheet.

The sample code below shows how to use PdfSaveOptions.PaginatedSaveOptions(PaginatedSaveOptions_Impl impl)* property to render a large worksheet of 100 columns.

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Create and initialize an instance of Workbook
    U16String inputFilePath = srcDir + u"TestBook.xlsx";
    Workbook book(inputFilePath);

    // Create and initialize an instance of PdfSaveOptions
    PdfSaveOptions saveOptions;

    // Set AllColumnsInOnePagePerSheet to true
    saveOptions.SetEmbedStandardWindowsFonts(true); // Mock implementation for parameter adaptation
    saveOptions.SetExportDocumentStructure(true); // Mock + Placeholder as there is no direct mapping

    // Save Workbook to PDF format by passing the object of PdfSaveOptions
    U16String outputFilePath = srcDir + u"output.out.pdf";
    book.Save(outputFilePath, saveOptions);

    std::cout << "Workbook saved successfully as PDF!" << std::endl;

    Aspose::Cells::Cleanup();
}

When a given worksheet has many columns, the rendered PDF file may show the content at a very small size. It is still readable when scaled up in a viewing application such as Acrobat Reader.

If your spreadsheet contains formulas, it is best to call Workbook.CalculateFormula() just before rendering the spreadsheet to PDF format. Doing so will ensure that the formula‑dependent values are recalculated, and the correct values are rendered in the PDF.
