Converting from Blob to pdf problem

Dear all

I have a small problem i hope someone can help me with. I wrote a code that saves a pdf in a database as blob, but when trying to retrieve this blob back and show it as a pdf i had a problem.

When i tried to show the pdf it appeared as a long stream like the following

%PDF-1.6 %âãÏÓ 27 0 obj <> endobj xref 27 21 0000000016 0000 ...............etc.

so it has the same structure of my original pdf except that it's a long stream in only one line . The original pdf looks like the following

%PDF-1.6
%âãÏÓ
27 0 obj
<</Linearized 1/L 82015/O 38/E 6717/N 1/T 81428/H [ 716 197]>>
endobj
                  
xref
27 21

............etc.

So if anyone can help to change that stream into a pdf again, i will really appreciate it. I attached the 2 files (the stream and the pdf).

Thanks in advance
