Add Poppler to Path in Debian

由 ℡╲_俬逩灬. 提交于 2019-12-13 02:39:25
问题 I have just installed poppler on my debian server using the command: sudo apt-get install poppler-utils However, when I execute the command: pdftocairo --help The function cannot be found, so I assume this program has not automatically linked into my PATH variable. My issue is that I am not very experienced with Linux and I don't know how to find out where poppler installed, nor how to create a link file to Poppler from an existing included PATH location. Any help would be appreciated,

read, highlight, save PDF programmatically

由 孤街浪徒 提交于 2019-12-12 08:24:21
问题 I'd like to write a small script (which will run on a headless Linux server) that reads a PDF, highlights text that matches anything in an array of strings that I pass, then saves the modified PDF. I imagine I'll end up using something like the python bindings to poppler but unfortunately there's next to zero documentation and I have next to zero experience in python. If anyone could point me to a tutorial, example, or some helpful documentation to get me started it would be greatly

how to extract pdf index/table-of-contents with poppler?

由 不羁的心 提交于 2019-12-06 11:27:25
问题 I see that pdf-viewers like okular and evince are able to display the index of a pdf document (book) very well, with link to every paragraph. How can they do so? They use poppler library, how could I do extract that index with poppler, or in general? 回答1: it just stops at first level (recursion needed to go more deeply) toc=document->toc(); QDomElement docElem = toc->documentElement(); QDomNode n = docElem.firstChild(); while(!n.isNull()) { QDomElement e = n.toElement(); // try to convert the

How to display PDF with python-poppler-qt4?

I have downloaded and installed python-poppler-qt4 and I am now trying out a simple Qt application to display a PDF page. I've followed what I've been able to get from the web, i.e. convert the PDF to a QImage, then to a QPixMap, but it doesn't work (all I get is a small window with no visible content). I may have failed at some point ( QImage.width() returns the width I have input, QPixMap.width() returns 0). Here is the code: #!/usr/bin/env python import sys from PyQt4 import QtGui, QtCore import popplerqt4 class Application(QtGui.QApplication): def __init__(self): QtGui.QApplication.__init_

How to display a PDF in its true scale with Poppler?

由 不想你离开。 提交于 2019-12-06 01:35:19
I am getting confused as to how to display a PDF document in its true scale, i.e. scale = 100%. NB: I am using python-poppler-qt4 . Poppler-qt4 provides a method to get the true size of the PDF in points : document = Poppler.Document.load('mypdf.pdf') page = document.page(0) size = page.pageSize() # returns a QSize object Then to render the page into a QImage , one should provide the resolution of the graphics device, in dots per inch (DPI): image = page.renderToImage(72, 72) Now since the natural size of the document is provided in points (i.e. 72 per inch), and the image renderer requires
