Basic Usage
++A typical way to parse a PDF file is the following: +
+ ++# Open a PDF file. +fp = open('mypdf.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. +doc = PDFDocument() +# Connect the parser and document objects. +parser.set_document(doc) +doc.set_parser(parser) +# Supply the document password for initialization. +# (If no password is set, give an empty string.) +doc.initialize(password) +# Check if the document allows text extraction. If not, abort. +if not doc.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 doc.get_pages(): + interpreter.process_page(page) +
+In PDFMiner, there are several objects involved in parsing a PDF file. +Figure 1. shows the relationships between these objects. + +
