PDFMiner - Iterating through pages and converting them to text

由 南楼画角 提交于 2019-12-21 05:22:09
问题 So I'm trying to get a specific bit of text out of some PDFs, and I'm using Python with PDFMiner but having some trouble due to the API changes to it that happened in November 2013. Basically, to get the part of text I want out of the PDF, I currently have to convert the entire file to text, and then use string functions to get the part I want. What I want to do is loop through each page of the PDF and convert each one to text, one by one. Then once I've found the part I want, I'll just stop

由 大憨熊 提交于 2019-12-20 05:34:08
问题 Camelot is a fantastic Python library to extract the tables from a pdf file as a data frame. However, I'm looking for a solution that also returns the table description text written right above the table. The code I'm using for extracting tables from pdf is this: import camelot tables = camelot.read_pdf('test.pdf', pages='all',lattice=True, suppress_stdout = True) I'd like to extract the text written above the table i.e THE PARTICULARS , as shown in the image below.

PDF text extraction returns wrong characters due to ToUnicode map

由 允我心安 提交于 2019-12-18 13:39:19
问题 I am trying to extract text from a foreign language PDF file using PDFMiner, but am being foiled by a ToUnicode statement. The file behaves strangely even under normal PDF viewers. For example, here is a screenshot from some text in the file: But if I select and copy the text, it looks like this: िनरकर You can see several characters have changed, in particular the second-to-last character. Not surprisingly, PDFMiner extracts the incorrect text. But every PDF viewer manages to display these

Why character ID 160 is not recognised as Unicode in PDFMiner?

由 那年仲夏 提交于 2019-12-14 03:00:21
问题 I am converting .pdf files into .xml files using PDFMiner. For each word in the .pdf file, PDFMiner checks whether it is Unicode or not (among many other things). If it is, it returns the character, if it is not, it raises an exception and returns the string "(cid:%d)" where %d is the character id, which I think is the Unicode Decimal. This is well explained in the edit part of this question: What is this (cid:51) in the output of pdf2txt?. I report the code here for convenience: def render
