Set margin of output pdf

I use viewer to view spreadsheet as pdf.
viewer.View(pdfViewOptions) with spreadsheetOptions

I notice that we have in output file margins around spreadsheet data.
I not found any options to configure that.
Can I set these margins to another value (or disable it)?

I Use .NET 6 and GroupDocs.Viewer 22.11.0

This feature was added in GroupDocs.Viewer for .NET 23.4. The package is available at

You can use the following code to set margins in the output PDF

using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;
// ...

using (var viewer = new Viewer("invoice.xlsx"))
{
    var viewOptions = new PdfViewOptions();

    // Set margins for worksheets in the output pdf pages
    viewOptions.SpreadsheetOptions.LeftMargin = 0;
    viewOptions.SpreadsheetOptions.RightMargin = 0.5;
    viewOptions.SpreadsheetOptions.TopMargin = 1;
    viewOptions.SpreadsheetOptions.BottomMargin = -10; // set to default value

    viewer.View(viewOptions);
}

Have a nice day!
