2.9 Python BindingInstalling the PDFlib Python Edition. The Python 1 extension mechanism works byloading shared libraries at runtime. For the PDFlib binding to work, the Python interpretermust have access to the PDFlib Python wrapper:> Unix: the library pdflib_py.so (on Mac OS X: pdflib_py.dylib) will be searched in the directorieslisted in the PYTHONPATH environment variable.> Windows: the library pdflib_py.dll will be searched in the directories listed in thePYTHONPATH environment variable.Error Handling in Python. The Python binding installs a special error handler whichtranslates PDFlib errors to native Python exceptions. The Python exceptions can bedealt with by the usual try/catch technique:try:...some PDFlib instructions...except PDFlibException:print 'PDFlib Exception caught!'Configuring the old-style Python binding without Unicode support. By default, the Pythonbinding is Unicode-aware. For compatibility purposes we also supply a non-Unicode-awareversion of the Python binding. Although this is not recommended for newapplications, you may want to use the old-style Python binding without Unicode supportfor older applications which do not properly deal with Unicode strings. In this situationyou can configure the Python binding as follows:> Rename pdflib_py.so to nupdflib_py.so> Add the the following to your code:from nupdflib_py import *1.
