Hi!
I have a very strange behaviour while copying a file with PDFBoxs
PDFStreamParser (RC2).
I modfied RemoveAllText not to remove any text:
public static void main( String[] args ) throws IOException
{
...
PDDocument document = null;
try
{
document = PDDocument.load( new File(args[0]) );
if( document.isEncrypted() )
{
System.err.println( "Error: Encrypted documents are
not supported for this example." );
System.exit( 1 );
}
for( PDPage page : document.getPages() )
{
PDFStreamParser parser = new PDFStreamParser(page);
parser.parse();
List<Object> tokens = parser.getTokens();
List<Object> newTokens = new ArrayList<Object>();
for (Object token : tokens)
{
newTokens.add( token );
}
PDStream newContents = new PDStream( document );
OutputStream out = newContents
.createOutputStream(COSName.FLATE_DECODE);
ContentStreamWriter writer = new ContentStreamWriter(
out );
writer.writeTokens( newTokens );
out.close();
page.setContents( newContents );
}
document.save( args[1] );
}
finally
{
if( document != null )
{
document.close();
}
}
}
I open both PDFs with PDFDebugger and the Contents text view is equal for
both files (see second TJ!). In hex view there are differences with space
(20) an LF-Chars (0A), where eol seems to be inserted/replaced.

Consenquently the preview in PDFDebugger (page two!) is the same too.

But when opening the new PDF file with Adobe Reader 11.0.10.32 the text
has changed!! 1 is now ), but not für 2013!
Übungskarte 49 (INT )463), Karte )/INT ), Begleitheft für die
Kartenaufgaben im Fach Navigation für den SKS (Ausgabe 2013)
On page three Aufgabe is now Auf0abe.
I have no idea how this can happen. Is there information anywhere else
except in the TJ-Block? The file size (old 960 K, new 1041 K) is slightly
different for 81 pages.
This is the pdf
