Subject [jira] [Commented] (TIKA-1228) Embedded files not extracted properly from PDF
Date Tue, 04 Feb 2014 12:28:11 GMT

    [ https://issues.apache.org/jira/browse/TIKA-1228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13890610#comment-13890610

Tim Allison commented on TIKA-1228:

Y.  That's the point of open source. :)  Enjoy!

Now that I'm looking at this issue again, I dragged out some of my pre-Tika code for pdf attachments
using a different pdf library.  It looks like the pdf files I was coding against could have
the file name in a parent node and the actual bytes in a child or more distant descendant

Will see if I can dig up the triggering files and see if Tika needs any more mods on PDF attachment

private MyPDFAttachment lookForByteStream(COSDictionary dict, MyPDFAttachment attach, int
    COSName fCOSName = COSName.create("F");
    COSName efCOSName = COSName.create("EF");
    COSObject fObj = dict.get(fCOSName);
    COSObject efObj = dict.get(efCOSName);
    if (null != fObj){
        if (fObj.getClass() == COSString.class){
        } else if (fObj.getClass() == COSStream.class){
            return attach;
    if (null != efObj && efObj.getClass() == COSDictionary.class){ 
        int tmpI = recursiveDepth;
        return lookForByteStream((COSDictionary)efObj, attach, tmpI);	
    return null;
