[jira] [Created] (PDFBOX-1297) ExtractText fails to extract text
from packaged PDFs
Michael McCandless created PDFBOX-1297:
------------------------------------------
Summary: ExtractText fails to extract text from packaged PDFs
Key: PDFBOX-1297
URL: https://issues.apache.org/jira/browse/PDFBOX-1297
Project: PDFBox
Issue Type: Improvement
Components: Text extraction
Affects Versions: 1.6.0
Environment: Fedora 13 Linux
Reporter: Michael McCandless
Apparently a PDF is able to contain multiple files (like a Zip file); it's called
a PDF Package, described at
http://help.adobe.com/en_US/Reader/8.0/help.html?content=WSE034CA46-D08F-4fff-AA3C-FF04510DAEF0.html
I have a simple example PDF Package, containing two sub-PDFs, but ExtractText
fails to extract their text.
It does run successfully (no exceptions), but the text it extracts is just the boilerplate text
saying you should upgrade to Adobe Acrobat version 8 or later to view this PDF.

Michael McCandless updated PDFBOX-1297:
---------------------------------------
Attachment: PDFPackage.pdf
Example document showing that ExtractText doesn't extract the text from the embedded documents.
The document was created with Adobe Acrobat.
It renders fine with Acrobat Reader: I see the two PDFs and when I click on each I can see their text "PDF1" and "PDF2".

Michael McCandless updated PDFBOX-1297:
---------------------------------------
Attachment: testPDFPackage.pdf
PDFBOX-1297.patch
Patch, adding embedded PDF handling to ExtractText, plus a test case
(and test document).
I would really appreciate someone who's more familiar with PDFBox's
APIs having a look at what I did... I had to dig into various classes
that I don't really understand: PDDocumentCatalog,
PDDocumentNameDictionary, PDEmbeddedFilesNameTreeNode,
PDComplexFileSpecification, PDEmbeddedFile.
I only extract text for embedded PDFs but not other content-types.
I noticed Tika's parser also fails to visit embedded documents within
a PDF... I'll open a separate issue.
