PDF Conversion from 1.7 to 1.3

[tonyawad88]

Hello,

I am trying to load a pdf document with a file version of 1.7 and I want to convert it to 1.3.

I am using the following code:
"
Dim document As New PdfDocument

document.LoadFromFile("C:\Temp\test1.pdf")
document.FileInfo.Version = PdfVersion.Version1_3
document.SaveToFile("C:\Temp\01.pdf")
"
However when I open the document with Adobe Acrobat Reader it is telling me that the file version is PDF Version: 1.5 (Acrobat 6.x)

Any idea if this is just an Adobe problem in identifying the version that Spire.PDF creates ?
Or am I Doing something wrong ?

Thank you,
Antoine Awad
