pdf2txt

pdf2txt.py

pdf2txt.pyPDF文件中提取文本内容。它提取所有要以编程方式呈现的文本,即以ASCIIUnicode字符串表示的文本。它无法识别绘制为需要光学字符识别的图像的文本。它还为每个文本部分提取相应的位置,字体名称,字体大小,书写方向(水平或垂直)。访问受到限制时,您需要为受保护的PDF文档提供密码。您无法从没有提取权限的PD文档中提取任何文本。
$ pdf2txt.py -o output.html samples/naacl06-shinyama.pdf
(extract text as an HTML file whose filename is output.html)

$ pdf2txt.py -V -c euc-jp -o output.html samples/jo.pdf
(extract a Japanese HTML file in vertical writing, CMap is required)

$ pdf2txt.py -P mypassword -o output.txt secret.pdf
(extract a text from an encrypted PDF file)

PDFMiner.six

PDFMiner.six is a fork of PDFMiner using six for Python 2+3 compatibility
Build Status PyPI version
PDFMiner is a tool for extracting information from PDF documents. Unlike other PDF-related tools, it focuses entirely on getting and analyzing text data. PDFMiner allows one to obtain the exact location of text in a page, as well as other information such as fonts or 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 purposes than text analysis.
