Hi! What's up ?

* Did you find one issue? 
* Is it possible to extract swc to have readable/writable purePDF's files?

I have downloaded Samuels PDF and loaded it with purepdf. I have the following 
output on the console. There are error messages and an error dialog but the 
application continues to run:

readXRefStream: 61
readXRefStream: 10
TypeError: Error #1034: Type Coercion failed: cannot convert 
Vector.<int>@5efffb1 to org.purepdf.pdf.PdfObject.
Error #2044: Unhandled error:. text=number of entries in this xref subsection 
not found

I'm using Flex 4.1 SDK (build 16076) in an AIR application on Windows XP with 
purePDF of May 27th.

The errors seem to refer to the getInfo method. As I posted earlier on the 
mailing list I had other problems with this method. It seems to very much 
depend on the PDF you are reading whether you get an error or not. I can't, 
however, really understand what's going on.

Regards,
Thilo

I know about this problem, but PDFReader isn't completed at all yet.

Hi all,

I faced the error #1304 issue and tried to solved it, since the Coercition 
Failed Error is just a cast issue.
Alessandro, you should replace the offending line :
index.add( Vector.<int>( [ 0, size ] ) );
with :
index.add(new PdfNumber(0));
index.add(new PdfNumber(size));

Since PDFArray (the index variable) expect PDFObjects and not a Vector instance.

I can send you a patch about it.

Hope this helps !
Bruno

PS : Looks like the code in the trunk is a little bit unstable :-( I had to 
replace some file.readInt() with file.readByte() to make the code works as the 
official release.
