Creates PDFs from HTML rendered using chrome or chromium
Project description
Pychromepdf 
Pychromepdf is a Python package that lets you easily create PDFs by rendering HTML content using Chrome or Chromium as backend. It works without any external dependecies except a working installation of Chrome or Chromium that supports headless mode.
Installation
pip install pychromepdf

Rendering HTML bytestring to PDF
from pychromepdf import ChromePDF
# change to your chrome executable path
PATH_TO_CHROME_EXE = '/usr/bin/google-chrome-stable'
# if you're on MacOS
# PATH_TO_CHROME_EXE = '/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome'
if __name__ == '__main__':
# initialize chromepdf object
cpdf = ChromePDF(PATH_TO_CHROME_EXE)
# the html that need to be rendered into pdf
html_bytestring = '''
<!doctype html>
<html>
<head>
<style>
@media print {
@page { margin: 0; }
body { margin: 1.6cm; }
}
</style>
</head>
<body>
<h1>Hello, World</h1>
<h5> Generated using headless chrome </h5>
</body>
</html>
'''
# create a file and write the pdf to it
with open('test.pdf','w') as output_file:
if cpdf.html_to_pdf(html_bytestring,output_file):
print("Successfully generated the pdf: {}".format(output_file.name))
else:
print("Error generating pdf")

from flask import Flask, render_template, send_file
import tempfile
from pychromepdf import ChromePDF
app = Flask(__name__)
# change to your chrome executable path
PATH_TO_CHROME_EXE = '/usr/bin/google-chrome-stable'
# if you're on MacOS
# PATH_TO_CHROME_EXE = '/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome'
# initialize a chromepdf object
cpdf = ChromePDF(PATH_TO_CHROME_EXE)
# home route
@app.route('/')
def index():
return render_template('index.html',username="John")
# custom pdf route
@app.route('/getpdf',defaults={'username': 'John'})
@app.route('/getpdf/<username>')
def getpdf(username):
# get the rendered html as string using the template
rendered_html = render_template('index.html',username=username)
# create a temporary output file which will be deleted when closed
with tempfile.NamedTemporaryFile(suffix='.pdf') as output_file:
# create a pdf from the rendered html and write it to output_file
if cpdf.html_to_pdf(rendered_html,output_file):
print("PDF generated successfully: {0}".format(output_file.name))
try:
# send the file to user
return send_file(output_file.name,attachment_filename='awesome.pdf')
except Exception as e:
return str(e)
else:
print("Error creating PDF")
return "Error"
if __name__ == '__main__':
app.run(debug=True)
