[jira] [Commented] (TIKA-1103) Tika.parseToString(InputStream) does
not output the same content as parseToString(File)
[ https://issues.apache.org/jira/browse/TIKA-1103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13627923#comment-13627923 ]
Ken Krugler commented on TIKA-1103:
-----------------------------------
One possible explanation is that when you pass an InputStream to Tika, it can't use the file name suffix to help with detecting the file type. In the above, what happens if you explicitly process the input stream with the PDF parser?

> Tika.parseToString(...) outputs different results with the following PDF file (iPhone user guide in german, bug also happens with french).
> http://manuals.info.apple.com/de_DE/iphone_benutzerhandbuch.pdf
> 1.3 parseToString(File) : actual content (good)
> 1.2 parseToString(File) : actual content (good)
> 1.1 parseToString(File) : actual content (good)
> 1.3 parseToString(InputStream) : empty
> 1.2 parseToString(InputStream) : PDF binary shown as text
> 1.1 parseToString(InputStream) : PDF binary shown as text
> Simple test case:
> Tika tika = new Tika();
> File f = new File("iphone_benutzerhandbuch.pdf")
> TikaInputStream is2 = TikaInputStream.get(f);
> String st2 = tika.parseToString(is2); // inputstream
> String stt2 = tika.parseToString(f); // file
> assertTrue(st2.equals(stt2)); // false
