Convert Pdf to Jpg

[lthurman]

When trying to convert a pdf to Jpg, I can set frameNumber = 1 and the second page will come back. but frameNumber = 0 the method kicks the CPU to 100% and never comes back. Contractually I cannot just attach the PDF but I could email it to you. This seems to only happen to one portion of our PDFs, but it locks up our entire system when one comes in, no exceptions are thrown by your code. It is like a while loop if running wild.

Code: Select all

 
            public static MemoryStream PullPage(FileInfo fileInfo, int frameNumber)
        {
            MemoryStream ms = new MemoryStream();
            if (File.Exists(fileInfo.FullName))
            {
                using (Spire.Pdf.PdfDocument doc = new PdfDocument())
                {
                    try
                    {
                        doc.LoadFromFile(fileInfo.FullName);
// this is where the code locks up and never comes back.
                        System.Drawing.Image bmp = doc.SaveAsImage(frameNumber, PdfImageType.Bitmap, 200, 200);
                        bmp.Save(ms, ImageFormat.Jpeg);
                    }
                    finally
                    {
                        doc.Close();
                    }
                }
            }
            return ms;
      }
