Aspose.PDF Product Family

The thumbnail generated from the code below does not match the pdf. Run the attached code and extract the thumbnail from example_pdf.pdf. example_thumb.jpg illustrates the incomplete rendering.

private static void MakeThumbnail(string filePath, string thumbPath)
{
    //Load the document
    Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(filePath);

    using (FileStream imageStream = new FileStream(thumbPath, FileMode.Create))
    {
        //Create PNG device with specified resolution
        Aspose.Pdf.Devices.Resolution resolution = new Aspose.Pdf.Devices.Resolution(300);
        Aspose.Pdf.Devices.JpegDevice jpgDevice = new Aspose.Pdf.Devices.JpegDevice(resolution, 100);

        //Convert page 1 and save the image to stream
        jpgDevice.Process(pdfDocument.Pages[1], imageStream);

        //Close stream
        imageStream.Close();
    }
}
