How to Convert EML to PNG in Python

Converting emails into images is a more challenging process than you might think at first look. EML format itself needs to be parsed into its constituent HTML, which you then have to render, and then use that to create your images. All this can take a very long time to set up (believe me I know). That’s why today I will be showing you how to skip all of that by applying a simple API.

Starting things off, we will run this command for pip install, which will bring in our client library into the project.

pip install cloudmersive-convert-api-client

And now we can instance our API, provide it with an API key, and use that to call our function with the EML file as an argument.

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint
# Configure API key authorization: Apikey
configuration = cloudmersive_convert_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['Apikey'] = 'Bearer'
# create an instance of the API class
api_instance = cloudmersive_convert_api_client.ConvertDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))
input_file = '/path/to/file' # file | Input file to perform the operation on.
try:
# Convert Email EML file to PNG image array
api_response = api_instance.convert_document_eml_to_png(input_file)
pprint(api_response)
except ApiException as e:
print("Exception when calling ConvertDocumentApi->convert_document_eml_to_png: %s\n" % e)

Ta-da! All done. Super easy, huh?
