[jira] Created: (TIKA-584) Tika parse of some PDF files removes all
spaces between words
Tika parse of some PDF files removes all spaces between words
-------------------------------------------------------------
Key: TIKA-584
URL: https://issues.apache.org/jira/browse/TIKA-584
Project: Tika
Issue Type: Bug
Affects Versions: 0.8
Environment: Windows XP 3, OpenSuse 11.2
Reporter: Ajay Vohra
In the case of some pdf files (not all), when Tika.parse(InputStream) method is used, the content extracted from the returned reader has all spaces removed. This only happens for some PDF files: An example where this happens is: JavaEE6Tutorial.pdf (available from Oracle). There are many such files where this bug can be seen. I have even tried Tika snapshot 0.9 and the bug remains.
When PDFTextStripper is directly used, the extracted content is correct, with the spaces between words retained.

Ajay Vohra commented on TIKA-584:
---------------------------------
I tried the PDF files attached with TIKA-583, and Tika.parse(InputStream) parses it with the spaces intact. So, it does not appear that 583 and 584 are the same issues.

[jira] Updated: (TIKA-584) Tika parse of some PDF files removes all
spaces between words
Posted by "Ajay Vohra (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TIKA-584?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ajay Vohra updated TIKA-584:
----------------------------
Attachment: JavaEE6Tutorial.pdf
Please try to parse this attached PDF file with example code below and the resulting extracted text contains no spaces:
public class TestTikaExtractor {
public static void main(String[] args) {
try {
Tika tika = new Tika();
Metadata metadata = new Metadata();
Reader reader = tika.parse(new FileInputStream(args[0]), metadata);
if(metadata != null) {
String[] names = metadata.names();
for(int i=0; i < names.length; i++) {
System.out.print("Metadata: host:"+ names[i] + ":"+ metadata.isMultiValued(names[i])+ "[" );
String[] values = metadata.getValues(names[i]);
for(int j=0; j < values.length; j++) {
System.out.print(values[j]);
}
System.out.println( "]" );
}
}
PrintWriter pw = new PrintWriter(new File(args[1]));
char[] cbuf = new char[1024];
int nread = 0;
while((nread = reader.read(cbuf, 0, cbuf.length)) > 0) {
pw.print(new String(cbuf, 0, nread));
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
