Кодеки: Как преобразовать XLSX в PDF?

В этом разделе

SDK может конвертировать XLSX-документ в векторный PDF- или PDF/A-документ с текстом, ссылками и навигацией.

Вот C#/VB.NET код, который демонстрирует, как преобразовать XLSX-документ в PDF документ:

/// <summary>
/// Converts XLSX document to PDF document using ImageCollection and PdfEncoder classes.
/// </summary>
public static void ConvertXlsxToPdf(string xlsxFileName, string pdfFileName)
{
    // create image collection
    using (Vintasoft.Imaging.ImageCollection imageCollection = new Vintasoft.Imaging.ImageCollection())
    {
        // add XLSX document to collection
        imageCollection.Add(xlsxFileName);

        // create pdfEncoder
        using (Vintasoft.Imaging.Codecs.Encoders.PdfEncoder pdfEncoder = 
            new Vintasoft.Imaging.Codecs.Encoders.PdfEncoder(true))
        {
            // set comression for image resources
            pdfEncoder.Settings.Compression = Vintasoft.Imaging.Codecs.Encoders.PdfImageCompression.Jpeg;

            // save images of image collection to PDF document using PdfEncoder
            imageCollection.SaveSync(pdfFileName, pdfEncoder);
        }

        // dispose images
        imageCollection.ClearAndDisposeItems();
    }
}

VB.NET

''' <summary>
''' Converts XLSX document to PDF document using ImageCollection and PdfEncoder classes.
''' </summary>
Public Shared Sub ConvertXlsxToPdf(xlsxFileName As String, pdfFileName As String)
    ' create image collection
    Using imageCollection As New Vintasoft.Imaging.ImageCollection()
        ' add XLSX document to collection
        imageCollection.Add(xlsxFileName)

        ' create pdfEncoder
        Using pdfEncoder As New Vintasoft.Imaging.Codecs.Encoders.PdfEncoder(True)
            ' set comression for image resources
            pdfEncoder.Settings.Compression = Vintasoft.Imaging.Codecs.Encoders.PdfImageCompression.Jpeg

            ' save images of image collection to PDF document using PdfEncoder
            imageCollection.SaveSync(pdfFileName, pdfEncoder)
        End Using

        ' dispose images
        imageCollection.ClearAndDisposeItems()
    End Using
End Sub

Вот C#/VB.NET код, который демонстрирует, как cконвертировать XLSX-документ в PDF/A-1b документ:

/// <summary>
/// Converts XLSX document to PDF/A-1b document using ImageCollection and PdfEncoder classes.
/// </summary>
public static void ConvertXlsxToPdfA1b(string xlsxFileName, string pdfFileName)
{
    // create image collection
    using (Vintasoft.Imaging.ImageCollection imageCollection = new Vintasoft.Imaging.ImageCollection())
    {
        // add XLSX document to collection
        imageCollection.Add(xlsxFileName);

        // create pdfEncoder
        using (Vintasoft.Imaging.Codecs.Encoders.PdfEncoder pdfEncoder = 
            new Vintasoft.Imaging.Codecs.Encoders.PdfEncoder(true))
        {
            // set PDF/A-1b (ISO 19005-1, Level B conformance)
            pdfEncoder.Settings.Conformance = Vintasoft.Imaging.Pdf.PdfDocumentConformance.PdfA_1b;
            
            // set CMYK ICC profile, which is used by PDF/A converter as a profile in DefaulRGB color space
            pdfEncoder.Settings.PdfADefaultRgbIccProfileFilename = "DefaultRGB.icc";

            // set comression for image resources
            pdfEncoder.Settings.Compression = Vintasoft.Imaging.Codecs.Encoders.PdfImageCompression.Jpeg;

            // save images of image collection to PDF/A-1b document using PdfEncoder
            imageCollection.SaveSync(pdfFileName, pdfEncoder);
        }

        // dispose images
        imageCollection.ClearAndDisposeItems();
    }
}
