Is it possible to convert a html file containing a JavaScript chart to PDF in python?

Question

I am trying to convert a html file to pdf in python. The html file has a javascript chart.
At first, I used weasyprint and pdfkit modules but I found that the modules does not support javascript.
So now I am using wkhtmltopdf module. It convert most of the html code to pdf, except javascript. Is it possible to convert an html file containing a JavaScript chart to PDF in python?
or should I use another module?
Below is the JavaScript code that does not appear in the pdf file.

<script type="text/javascript">

FusionCharts.ready(function(){

  var fusioncharts = new FusionCharts({

  type: 'hlineargauge',

  renderAt: 'chart_container',

  width: '350px',

  height: '170px',

  dataFormat: 'json',

  dataSource: {

      "chart": {

          "theme": "fint",

          "caption": "Chart A",

          "lowerLimit": "0",

          "upperLimit": "20",

          "chartBottomMargin": "40",

          "valueFontSize": "11",

          "valueFontBold": "z0"

      },

      "colorRange": {

          "color": [{

              "minValue": "0",

              "maxValue": "11.5",

              "label": "Low",

              "code" : "#FDB881",

          }, {

              "minValue": "11.5",

              "maxValue": "12.5",

              "label": "Typical",

              "code" : "#F18B36",

          }, {

              "minValue": "12.5",

              "maxValue": "20",

              "label": "High",

              "code" : "#D2660D",

          }]

      },

      "pointers": {

          "pointer": [{

              "value": "8",

              'borderColor':'#333333',

              'borderThickness':'3',

              'borderAlpha':'100',

              'bgColor':'#FF0000'
          }]
      },
  }
}
);
  fusioncharts.render();
});
</script>

wkhtmltopdf version is 0.12.4 and the command is

$ wkhtmltopdf --javascript-delay 5000 test.html test.pdf

Here is an example from a previous StackOverflow question. How to convert webpage into PDF by using Python

This example uses the library pfdkit

import pdfkit
pdfkit.from_url('http://google.com', 'out.pdf')

If it doesn't render the chart you could try using an iFrame with pdfkit to get desired results!

Here is an example using WeasyPrint First, install weasyprint.

pip install weasyprint

Then run example

python
>>> pdf = weasyprint.HTML('http://www.google.com').write_pdf()
>>> len(pdf)
92059
>>> file('google.pdf', 'w').write(pdf)

Here is a third example, because i'm fun. :)

import sys 
from PyQt4.QtCore import *
from PyQt4.QtGui import * 
from PyQt4.QtWebKit import * 

app = QApplication(sys.argv)
web = QWebView()
web.load(QUrl("http://www.yahoo.com"))
printer = QPrinter()
printer.setPageSize(QPrinter.A4)
printer.setOutputFormat(QPrinter.PdfFormat)
printer.setOutputFileName("fileOK.pdf")

def convertIt():
    web.print_(printer)
    print "Pdf generated"
    QApplication.exit()

QObject.connect(web, SIGNAL("loadFinished(bool)"), convertIt)
sys.exit(app.exec_())

Thank you Steven. Actually the websites is rendered well but I don't know why my javascript chart in a html file is not rendered.

user8320550 Over a year ago

Maybe try using $(function() { }); so it's rendered when the page loads ? Maybe it's running the script before loading all of it ?

Not working even after wrapping it in $(function() { }); any suggestions @BingbongKim

WeasyPrint doesn't execute JavaScript. See the issue
