    Optimize spreadsheets in a PDF file

    On this page

    This optimization allows to reduce the output file size by setting up border lines. Besides that, it removes the Arial and Times New Roman characters of 32-127 codes.

    The default value is false.

    The following code snippet shows how to optimize spreadsheets in a PDF file:

    using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;
using GroupDocs.Viewer.Domain.Documents.PostProcessing.Pdf.Optimization;
// ...

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

    viewer.View(viewOptions);
}
