Simple PDF text extraction
import pdftotext
# Load your PDF
with open("lorem_ipsum.pdf", "rb") as f:
pdf = pdftotext.PDF(f)
# If it's password-protected
with open("secure.pdf", "rb") as f:
pdf = pdftotext.PDF(f, "secret")
# How many pages?
print(len(pdf))
# Iterate over all the pages
for page in pdf:
print(page)
# Read some individual pages
print(pdf[0])
print(pdf[1])
# Read all the text into one string
print("\n\n".join(pdf))Debian, Ubuntu, and friends:
sudo apt-get update
sudo apt-get install build-essential libpoppler-cpp-dev pkg-config python-dev
Fedora, Red Hat, CentOS 7 and friends:
sudo yum install gcc-c++ pkgconfig poppler-cpp-devel python-devel redhat-rpm-config
CentOS 6:
sudo yum install gcc-c++ pkgconfig python-devel redhat-rpm-config
On CentOS 6 the libpoppler-cpp library is not included with the system so we need to build from source. Following the instructions from this link, note that recent versions of poppler require C++11 which is not available on CentOS, so we build a slightly older version of libpoppler.
# Build dependencies
sudo yum install wget xz libjpeg-devel openjpeg2-devel
# Download and extract
wget https://poppler.freedesktop.org/poppler-0.47.0.tar.xz
tar -Jxvf poppler-0.47.0.tar.xz
cd poppler-0.47.0
# Build and install
./configure
make
sudo make install
By default libraries get installed in /usr/local/lib and /usr/local/include. On CentOS this is not a default search path so we need to set PKG_CONFIG_PATH and LD_LIBRARY_PATH to point R to the right directory:
export LD_LIBRARY_PATH="/usr/local/lib"
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
macOS:
brew install pkg-config poppler
Conda users may also need libgcc:
conda install libgcc
pip install pdftotext
