Load a PDF for conversion from a stream in C#

PDF

To load a PDF document for conversion from a stream, use the LoadFromStream method from the GdPictureDocumentConverter class.

LoadFromStream accepts:

  • Stream — The input stream containing the document data.
  • DocumentFormat (optional) — A member of the DocumentFormat enumeration. For PDF, use DocumentFormat.DocumentFormatPDF.

LoadFromStream returns a GdPictureStatus, which should always be checked before conversion.

To load and convert a PDF document from a stream, use the following code:

using GdPicture14;
using System;
using System.IO;


// Create a stream object from a PDF file.
using Stream streamFile = new FileStream(@"C:\temp\source.pdf", FileMode.Open, FileAccess.Read);
using GdPictureDocumentConverter converter = new GdPictureDocumentConverter();


GdPictureStatus status = converter.LoadFromStream(streamFile, DocumentFormat.DocumentFormatPDF);
if (status != GdPictureStatus.OK)
{
    Console.WriteLine($"LoadFromStream failed: {status}");
    return;
}


// Convert PDF to TIFF.
status = converter.SaveAsTIFF(@"C:\temp\output.tif", TiffCompression.TiffCompressionAUTO);
if (status != GdPictureStatus.OK)
{
    Console.WriteLine($"SaveAsTIFF failed: {status}");
}
