Is it possible to parse pdf files with a python script in ignition with a 3rd party Library like pdfminer or  
Jython + pdfbox ?

Not trivial, but possible.

You could create a module with the Ignition SDK adding the pdfbox jars to it and then, call the functions from jython code.

A quick view on PDF Miner (I used pdfbox, not PDF Miner) seems to be a pure python 2.4 library (not a wrapper from CPython, like anothers third party librarys that are not compatible with Ignition), so, if you have Ignition 7.7.x, you could add this as a third-party python library.

I have just tried exactly what you describe before with pdfminer  
I have added pdfminer folder in pylib (…\Inductive Automation\Ignition\user-lib\pylib)  
Ignition recognize the new python library (I have a message wich inform me Ignition has found a new library in pylib)

I have added without problem the following sample script on a button:

from pdfminer.pdfparser import PDFParser  
from pdfminer.pdfdocument import PDFDocument  
from pdfminer.pdfpage import PDFPage  
from pdfminer.pdfpage import PDFTextExtractionNotAllowed  
from pdfminer.pdfinterp import PDFResourceManager  
from pdfminer.pdfinterp import PDFPageInterpreter  
from pdfminer.pdfdevice import PDFDevice

# Open a PDF file.

fp = open(‘C:\PyhtonScripts\HelloWorld.pdf’, ‘rb’)

# Create a PDF parser object associated with the file object.

parser = PDFParser(fp)

# Create a PDF document object that stores the document structure.

# Supply the password for initialization.

document = PDFDocument(parser, password)

# Check if the document allows text extraction. If not, abort.

if not document.is\_extractable:  
raise PDFTextExtractionNotAllowed

# Create a PDF resource manager object that stores shared resources.

rsrcmgr = PDFResourceManager()

# Create a PDF device object.

device = PDFDevice(rsrcmgr)

# Create a PDF interpreter object.

interpreter = PDFPageInterpreter(rsrcmgr, device)

# Process each page contained in the document.

for page in PDFPage.create\_pages(document):  
interpreter.process\_page(page)

But unfortunately I have a Java run time error:

ERROR [ActionAdapter-MainThread] Error executing script for event:&nbsp;`actionPerformed`

Mmmm… pretty strange… I’m not an expert but seems that java classes must not exceed a determinated size (according to jvm specifications, a class may not exceed 64KB) and maybe Ignition dynamically compile the python code (jython) to a java class and if the python code it’s too big, not work…

I can’t think a quickly workaround to this… maybe a more expert jython users or some guys from IA could help you…

You still have the pdfbox approach…

Yes I am going to look at the pdfbox approach, I’ve just downloaded the sdk. Thanks for your advices, Regards
