Python PDF parser and analyzer
PDFMiner is a suite of programs that help extracting and analyzing text data of PDF documents. Unlike other PDF-related tools, it allows to obtain the exact location of texts in a page, as well as other extra information such as font information or ruled lines. It includes a PDF converter that can transform PDF files into other text formats (such as HTML). It has an extensible PDF parser that can be used for other purpoes instead of text analysis.

CMap
,
which is distributed from Adobe.
Here is how:
CMap
directory under the directory
where pdfminer
is installed.
(Normally this should be something like /usr/lib/python2.5/site-packages
.)
For example:
$ cd /usr/lib/python2.5/site-packages $ tar jxf CMap.tar.bz2
This may take several minutes.$ python -m pdfminer.cmap
PDFMiner comes with two handy tools:
pdf2txt.py
and dumppdf.py
.
pdf2txt.py
extracts text contents from a PDF file.
It extracts all the texts that are to be rendered programatically,
i.e. it cannot extract texts drawn as images that require optical character recognition.
It also extracts the corresponding locations, font names, font sizes, writing
direction (horizontal or vertical) for each text portion.
You need to provide a password for protected PDF documents when its access is restricted.
You cannot extract any text from a PDF document which does not have extraction permission.
For non-ASCII languages, you can specify the output encoding (such as UTF-8).
Note: Not all characters in a PDF can be safely converted to Unicode.
Examples:
$ pdf2txt.py samples/naacl06-shinyama.pdf > output.html (extract text as an HTML file whose filename is output.html) $ pdf2txt.py -c euc-jp samples/jo.pdf > output.html (extract a Japanese HTML file in vertical writing, CMap is required) $ pdf2txt.py -P mypassword -t text secret.pdf > output.txt (extract a text from an encrypted PDF file)
Options:
-o filename
-p pageno[,pageno,...]
-c codec
-t type
html
: HTML format. (Default)
text
: TEXT format.
sgml
: SGML format.
tag
: "Tagged PDF" format. A tagged PDF has its own contents annotated with
HTML-like tags. pdf2txt tries to extract its content streams rather than inferring its text locations.
Tags used here are defined in the PDF specification (See §10.7 "Tagged PDF").
-P password
-d
dumppdf.py
dumps the internal contents of a PDF file
in pseudo-XML format. This program is primarily for debugging purpose,
but it's also possible to extract some meaningful contents
(such as images).
Examples:
$ dumppdf.py -a foo.pdf (dump all the headers and contents, except stream objects) $ dumppdf.py -T foo.pdf (dump the table of contents) $ dumppdf.py -r -i6 foo.pdf > pic.jpeg (extract a JPEG image)
Options:
-a
-p pageno
-p
options are allowed.
Note that page numbers start from one.
-r
(raw)
-b
(binary)
-t
(text)
With -r
option, all the stream contents are dumped without decoding.
With -b
option, the contents are dumped as a binary blob.
With -t
option, the contents are dumped in a text format,
similar to repr()
manner. When
-r
or -b
option is given,
no stream header is displayed for the ease of saving it to a file.
-P password
-d
