I need tight integration and no remote service calls, thats why it seems bit tricky to me., and i am working to integrate Python implementation in .NET. So where the .NET application has to work with PDF part, it will invoke the IronPython Engine, pass required configurations and parameters, and get the result+exceptions etc. > > http://pybrary.net/pyPdf/ Noted for my reference.

But i am unable to find any good documentation. I think i will have to buy the book, so that I can have API docs just beside me for reference. One thing I am stuck at right now. the IronPython 1.0.2467 on .NET 2.0.50727.42 is installed on my Ubuntu, so does CPython 2.5 libraries can be called in it without any problem. In ipy shell, >>> sys.path ['/home/rskumar', '/usr/lib/ironpython/Lib', '/usr/lib/python2.4', '/usr/lib/python2.4/site-packages'] >>> so it uses Python 2.4 libs. I am fearing to mix the 2.4 and 2.5 libs. I need to load CPython 2.5 libs by adding it in site.py file of ironpython. Maybe I should go experimenting and let you people know about it. -- -=Ravi=- -- http://mail.python.org/mailman/listinfo/python-list

But that is most generation of PDFs. For reading, splitting, etc, you may have to look at their commercial offering. And I do believe it is all pure python.

In continuation of last mail [since pressing tab+space sent the mail :( ] Things on high priorities right now are: - How to integrate Python calling from .NET - Any suggestions for optimizations that would prevent overburden to application due to IronPython interpretation calling, if any, or does such things happen. - Pointers to good resources - Any step in such kind of situation, so to make it Enterprise Grade application components - your opinion with available PDF Libraries, that are best among. Also which library to use for Windows server platform (there is limitation on installing long chain libraries that include other deep dependencies too). A pure python PDF library would be good, but which one. -Which XML Library is pure python based. More questions will follow up :) And I hope, people will reply me. -- -=Ravi=- -- http://mail.python.org/mailman/listinfo/python-list
.NET and Python Integration Problem and PDF Library (Need Help and Suggestions)
Hi. First I am explaining the Problem so it would not get messed up. :) == PROBLEM I have to integrate a small part in .NET Projects. .NET project is actually all Web-based application, user interface is Web-page for multiple actions. But a backend component of project needs PDF File manipulation. Manipuation is limited to splitting pages, removing certain pages, joining pages, finding certain text information (Title/Author/No. of Pages/Orientation of each page etc), and page orientation maipulation (rotating pages clockwise and anticlockwise, on degree parameter, left/right/flip etc). .NET guys are failing here, so I proposed to do that component in Python. But problem is, how to integrate Python in .NET Web Application. I am looking on IRONPYTHON, and thats the only point seemed to me. Also, as I am not an expert in Python, I have transition from Perl and PHP to python. So right now, my applciation architecture would little bit be inexperienced and not enterprise ready. But every component in project is being worked on Enterprise grade. Now, I want to integrate Python implementation for PDF works, and that would be called from .NET (C#) processes supplying required parameters. Since the whole application would be implemented on MS Windows Server, so I am bit lacking the freedom of library usage as in Linux. Also looking for best PDF library which doesn't have any or many dependencies and that dependencies can be successfully installed. I will also need an XML Library to write down the logs and instructions+information for next component which handles Printing. = Therefore, I am seeking all the precious (even small or one-liner) advices from you. Please suggest me every possible things that come in your mind. Things on high priorities right now are: -- -=Ravi=- -- http://mail.python.org/mailman/listinfo/python-list
