[jira] [Commented] (PDFBOX-1762) org.apache.pdfbox.cos.COSInteger cannot be cast to org.apache.pdfbox.util.PDFOperator

["Tilman Hausherr (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-1762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14008782#comment-14008782 ] 

Tilman Hausherr commented on PDFBOX-1762:
-----------------------------------------

The PDF, and the stream are broken. Here's the stream that PDFStreamParser doesn't like:
{code}
BI
/W 2
/H 2
/BPC 1
/IM true
/D [ 1 0 ] 
ID ÀÀ
EI
Q 
q 
3 
q 
4.5 0 
0.9216 0.85498W 2
/H9176 0.85BPC 1
/IM true
 true

BI
/W 2
/H 1
/BPC 1
/IM true
/D [ 1 0 ] 
ID À

{code}
starting with the line "0.9216 0.85498W 2", it doesn't make sense anymore "/W 2" is a correct command, but "0.9216 0.85498W 2" isn't and it gets worse from there. There's a comment by Andreas or Timo in another of your issues, that he thinks that two threads wrote on the same output at the same time.
