Exports a PDF document to a TIFF image using a stream, the image’s largest edge length, and page numbers.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Docs.v20.2.dll

NuGet Package: DevExpress.Document.Processor

NuGet Packages: DevExpress.Document.Processor, DevExpress.WindowsDesktop.Document.Processor

Declaration

C#

public void CreateTiff(
    Stream stream,
    int largestEdgeLength,
    IEnumerable<int> pageNumbers
)

VB.NET

Public Sub CreateTiff(
    stream As Stream,
    largestEdgeLength As Integer,
    pageNumbers As IEnumerable(Of Integer)
)

Parameters

Name	Type	Description
stream	Stream	A Stream object that is a stream to which the TIFF image should be written.
largestEdgeLength	Int32	An integer value, specifying the length of the image’s largest dimension, in pixels.
pageNumbers	IEnumerable<Int32>	A list of page numbers which implement the IEnumerable<T><Int32,> interface.

Remarks

The largestEdgeLength parameter determines the output image height for pages with portrait orientation and width - for landscape pages.

Note

The CreateTiff method works on Azure Windows Virtual Machines and does not work on Azure Web Apps.

The following example shows how to convert pages to a multi-page Tiff image.

C#

using DevExpress.Pdf;

namespace ExportToTiff
{
    class Program
    {
        static void Main(string[] args)
        {

            int largestEdgeLength = 1000;
            int[] pageNumbers = new int[] { 1, 3, 5 };

            // Create a PDF Document Processor.
            using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
            {
                // Load a document.
                processor.LoadDocument("..\\..\\Document.pdf");

                // Export pages to a multi-page tiff image.
                processor.CreateTiff("..\\..\\Image.tiff", largestEdgeLength, pageNumbers);
            }
        }
    }
}

VB.NET

Imports DevExpress.Pdf

Namespace ExportToTiff
    Class Program
        Private Shared Sub Main(ByVal args As String())
            Dim largestEdgeLength As Integer = 1000
            Dim pageNumbers As Integer() = New Integer() {1, 3, 5}

            Using processor As PdfDocumentProcessor = New PdfDocumentProcessor()
                processor.LoadDocument("..\..\Document.pdf")
                processor.CreateTiff("..\..\Image.tiff", largestEdgeLength, pageNumbers)
            End Using
        End Sub
    End Class
End Namespace

The CreateTiff method uses GDI/GDI+ rendering and works only on Windows OS. The PlatformNotSupportedException is thrown on other operating systems.
