c# - iTextSharp doesn't work with PDF generated by Fax machine? -

i have class extract images pdf file, using itextsharp.

i tested pdf generated scan machine, worked fine.

then, tested pdf generated fax machine, got ioexception: .pdf not found file or resource.

i don't have clue why didn't work pdf fax machine. itextsharp not support pdf fax machine or something?

any thought appreciated. thanks

edit

public list<image> extractimagesfromfax(string sourcepdf)     {         var imglist = new list<image>();          try         {                             var pdfreader = new pdfreader(sourcepdf); //error here ...              (var = 0; <= pdfreader.xrefsize - 1; i++)             {                 //code here             }             pdfreader.close();                         }         catch(exception ex)         {             console.writeline(ex.message);         }          return imglist;     } 

i tried read pdf itextsharp.text.pdf.pdfreader, got ioexception couldn't go further (only happened pdf generated fax machine).

pdf files:

• fax: https://www.box.com/s/xwwu5xziujay153y67rz

• scan: https://www.box.com/s/9tlqqwixw1w9b2znh1j2

the ioexception says you're trying open file named ".pdf". 1 expect file named "somefile.pdf", have dot , extension pdf. sure name of file want read? sure code correct?

note exception isn't thrown itext class. pdfreader uses c# class trying open file, , it's c# class tells file can't found. can mean 2 things:

1. you didn't use correct path.
2. the application wrote doesn't have sufficient permissions access file.

you can check writing code reads file byte array without using itext. if fails, you've found problem.
