[jira] Created: (PDFBOX-586) Text Extraction Regression ?

Text Extraction Regression ?
----------------------------

                 Key: PDFBOX-586
                 URL: https://issues.apache.org/jira/browse/PDFBOX-586
             Project: PDFBox
          Issue Type: Bug
          Components: Text extraction
    Affects Versions: 0.8.0-incubator
         Environment: Windows XP + Eclipse + PDFBox sources
            Reporter: Bernard


Hi,

I have noticed that I can extract text some PDF files in PDFBox 0.7.3 but for the same file, the same page, PDFBox 0.8.0 doesn't retreive any text.
The text is in english (ascii char).  I have around 40% of my pdf file with this problem.

Am I the only only one who think there is a regression in text extraction ?

--------------------------------

Hi,

I have founded something strange.

If I use the jar files ( commons-logging-1.1.1.jar fontbox-0.8.0-incubating.jar jempbox-1.0.0.jar pdfbox-0.8.0-incubating.jar )  the text extraction is OK for a specific test file, for the 1st page.

If I use the Source Code of  fontbox-0.8.0-incubating.jar jempbox-1.0.0.jar pdfbox-0.8.0-incubating.jar  :  the text extraction returns nothing for the 1st page.  I have commented/removed encryption stuff as well as Logs.

All for version 0.8.0

Are you the the sources code are the one which created the .jar ?


(I would need source code, because I use PDFBox on Android devices, and I need to remove all unnessary stuff : tests, logs, printf, colors management, fonts managements, ...).  Including directly .jar would make a too big executable.

--------------------------------

I too have noticed some regression in text extraction since 0.7.3 (compared to rev886875 from 1 Dec 2009). I used that to read some newer PDFs but certain older PDFs no longer extract text.

A specific failing example (which I'm not able to share for comercial reasons), had the following characteristics:
Generated by: PDFlib+PDI 7.0.1p1 (.NET/Win32)
Format: PDF-1.6
Papersize: US Letter, Landscape (279 x 216 mm)

Text extraction is OK with this file in PDFBox 0.7.3, but not in 0.8.0.

I have others bigger (>5Mo) samples files if you need.
