Introduction

This note shows how to iteratively retrieve the decoded content of the pages in a PDF file using Python and the pdfminer Python package.

At the time of writing, the latest version of pdfminer was used, i.e., 20140328. Thus, as the package seems poorly maintained and prone to API-breaking changes one may have to explicitly install this version for the following code to work.

Code

The following generator will iterate over a PDF file under a given filename and iteratively yield the text content of each PDF page:

ssh-keygen -t rsa -b 4096 -m PEM -f jwtRS256.key
# Don't add passphrase
openssl rsa -in jwtRS256.key -pubout -outform PEM -out jwtRS256.key.pub
cat jwtRS256.key
cat jwtRS256.key.pub
