[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)

Bernard updated PDFBOX-586:

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.
