XPS Conversion


I have to convert files to XPS format.
I have downloaded the latest version of Aspose.Word, Aspose.Pdf, Aspose.Slides, Aspose.Cells

I have used two files for each type of file. A big ( more than 7 Mo) and a small ( less than 300 Ko).

Here is my source code

Aspose.Words.Document worddoc= new Aspose.Words.Document(@"c:/DocSoure/doc_big.doc");
using ( FileStream fsz = new FileStream(@"c:/Docconverted/doc_big.xps"), FileMode.Create))
worddoc.Save(fsz, Aspose.Words.SaveFormat.Xps);

I'm using the "same template" for each type of file.

Here are the restults of the conversions.

Word files

  • Original size 31 Mo
    Time to convert : 17 seconds
    converted size : 30 MO
  • Original size 231 Ko
    Time to convert : 0.1 seconds
    converted size : 252 Ko

Xls files

  • Original size 18 Mo
    Time to convert : 97 seconds
    converted size : 11 Mo
  • Original size 104 Ko
    Time to convert : 0.6 seconds
    converted size : 126 KO

PPT files

  • Original size 7 Mo
    Time to convert : 14 seconds
    converted size : 10 Mo
  • Original size 546 Ko
    Time to convert : 0.8 seconds
    converted size : 608 Ko

PDF files

  • Original size 17 Mo ( 52 pages )
    Time to convert : 4.8 seconds
    converted size : 1 Mo ( Only 4 pages !!!!!! )
  • Original size 201 Ko
    Time to convert : 3.1 seconds
    converted size : 1 Mo ( Only 4 pages !!!!!! )

I have 2 questions

Are these performances expected?

Word file 31Mo : 17 seconds
Xls file 18Mo : 97 seconds
PPT file 7Mo : 14 seconds
PDF file 201Ko : 4.8 seconds

Why do I have only 4 pages for the pdf conversion?

We have no issues for example converting Word to image format ( one image for each page)

Our aim is to display those files in the "first floor Silverlight" viewer. But with these performances we won't be able to deploy it.
