Convert word to pdf exception

I’m trying to convert a 5M(200pages) word document to a protected pdf file.
The following codes throw a exception:"_CPMPlusException"
jpedDevice.Process(pdf.Pages[pageCount], imageStream);
I need your help.
My OS is Windows Vista Business Service Pack 2 architecture 32-bit;
Thank you!

Hi Chen,

Thanks for your inquiry. In case you're using an older version of Aspose.Words, I would suggest you please upgrade to the latest version from the following link:

In case the problem still remains, please attach your input Word document and source code here for testing. We will investigate the issue on our end and provide you more information.

Best regards,


I downloaded the latest version of Aspose Words. But my license is old. I would make sure that the latest version have no problem. Then I will buy a new license.

Now I have a new problem. When I use the latest version of Aspose Words with my old license, the following codes throw a new exception:"indexOutOfRangeException"

Document wordFile = new Document(stcPath);
wordFile.Save(“xxx.pdf”, potions);
Document tempPdf = new Aspose.Pdf.Document(“xxx.pdf”);
for (int pageCount = 1; pageCount <= tempPdf.Pages.Count; pageCount++)
using (FileStream imageStream = FileStream(tempfile, FileMode.Create))
Rectangle rect = tempPdf.Pages[pageCount].Rect;
jpegDevice.Process(tempPdf.Pages[pageCount], imageStrem);
Page page = tempPdf.Pages[pageCount];
page.Rect = rect;
double upperRightX = rect.Width;
double upperRightY = rect.Height;
page.Contents.Add(new Operator.GSave());
Rectangle rectangle = new Rectangle(0.0, 0.0, upperRightX, upperRightY);
Matrix matrix = new Matrix(new double[] {rectangle.URX - rectangle.LLX, 0, 0, rectangle.URY - rectangle.LLY, rectangle.LLX, rectangle.LLY});
page.Contents.Add(new Operator.ConcatenateMatrix(matrix));
XImage ximage = page.Resources.Images[page.Resources.Images.Count];
page.Contents.Add(new Operator.Do(ximage.Name));
I want to know whether my old license cause this problem or not.

When I testing with the older version of Aspose, I found another problem.

the following code throw a exception:“Encryprion of huge stream is not implemented”;

tempPdf.Encrypt(string.Empty, string.Empty, 0, CryptoAlgorithm.RC4x128);

Whether Aspose limit the stream’s size? My tempPdf’s size is bigger than 200M;
